How to buy it a PC. If a PC is bought, it's on the weekend which becomes inexpensive.

It's necessary to check it variously to buy a PC profitably. When buying a PC, I'm checking various things. The time when something new is being chosen and checked is fun again, isn't it?

How will I choose and buy or introduce a PC? It's my personal idea, but please consult.

 

First it's choice of "Mac" and "Windows" to waver, isn't it? I just see mailing and the internet, don't need the function of the other PCs so much and like "Macintosh of Apple" in designing way, "Mac", may, when, I think. I think the one which deals with music, a picture and image processing specially is also preferred by Mac.

When using both for good in case of, blog and business in particular, I think it's safe to make it "Windows PC". When a person of Windows didn't understand any more, because it can be heard a friend has that.

 

I make the PC something new in around about 3.
Mac->  Gateway->  EPSON (Endeavor)->  DELL->  It was changed with Lenovo (ThinkPad).

The performance of the OS and the software falls, and I think the life expectancy of the hardware is about about 3 years a DVD drive and a built-in battery. When it's used for more than 3 years indeed, a battery and a DVD drive don't become working well for my PC. When the registry where basic information on Windows and expansion information on software are preserved (Registry) is also used for a long time, a lot of information is written in, and a PC is becoming slow in response.

When there was VersionUp of big OS around around 3 in case of me, purchase is considered.

 

There are a way to buy "Yamada electricity" by volume retailers of consumer electronics and a way to buy it at a Web site such as DEL and Lenovo for a PC. Various software attaches in case of me, and I'd like to choose the HDD capacity, keyboard arrangement and the resolution as freedom, not All in One-type where the HDD capacity and the memory capacity are decided, so it's bought at a Web site.

In case of me, the standard of the PC election esteems "keyboard arrangement" and "the resolution of the monitor". Anything by which PageUp and PageDown serve also as an arrow key isn't chosen. The resolution chooses something to have that as much as possible. The screen size is big, but I have the one with the low resolution for good one fairly. For example though it's a monitor, 15 inches of resolution is XGA.

 

I think I'd like the one as new as possible for OS. I think Windows7 is better than Windows Vista. Improvement of UAC and start speed are raised.

Even 64bit edition can also use software of an edition 32 bits, so I think it's better to make it 64bit edition, but there is software which can't be used no matter what by 64bit edition. The price is also same, so you like this neighborhood, right?

 

It becomes last, but the trick to buy it inexpensively is to buy it on a weekend. "KAKAKU. com" we assume that it's natural to confirm the price and the word-of-mouth communication by a comparative site of etc., and a low coupon comes into effect at the weekly end on the Web site of Dell and Lenove. It's important to use this.

It'll be a weekend that it was 5%Off on weekdays in 20%Off. When it was 100,000 yen, it's 95000 yen of holiday on weekdays, 80000 yen. This gap is great, isn't it?

It is not possible to do in simple NAS, and if it is a link station, PC synchronization power supply On/Off can be done.

When HDD is connected to LAN, I'm interested in keeping putting a power supply. BUFFALO LinkStation is connected with a start of a PC, and On of a power supply/Off is made.

 

Even if it isn't HDD for LNA connections of NAS exclusive use like LinkStation in Buffalo, it's possible to make the USB HDD simple NAS. There is USB joining terminal in recent wireless LAN equipment, and simple NAS can be built by connecting a USB memory and HDD. But connected HDD keeps being turned on, and there is only an energy saving function which just stops revolving around HDD.

Wireless LAN equipment with simple NAS makes a schedule in time, and, a power supply, On/Off, can, I have that. When I'd like to use it in power supply Off, wireless LAN equipment is to press its own button, and the start is possible.

But using it at midnight suddenly, and without sticking at time, I'd like to use a PC freely. I don't want to go to the location of the wireless LAN equipment one by one.

 

So! It's BUFFALO LinkStation. I bought "LS-CH1.5TL". The life expectancy of the power-saving and the HDD, I'm quite satisfied with the angle of the security. It may be better to let a power supply putting the life expectancy of the HDD. . HDD equipment which corresponds is limited to the simple NAS function, and it's also a reason that the HDD I possess was non-applicable.

The power supply which is connected, and HDD (LS-CH1.5TL) when LS-CH1.5TL turns on the power of a PC, On. And the power supply which is connected, and HDD when shut down does a PC, Off. It corresponds to more than one PC. When even 1 PC has started, when a power supply of On and all PCs is Off, a power supply of HDD will be a power supply of HDD in Off.

 

HDD for NAS of IO data, a PC power supply, connected, for, a revolution of the HDD which cries is just stopped, but it's the merit to be able to use it as USB HDD. LinkStation is good for the power supply connected function, as expected, it's slower in speed than USB HDD of PC direct connection. You hesitate about whether you get advantage convenience or get speed, right?

A wireless LAN When the cordless handset side doesn't correspond to a double speed mode of 11n, at most 300 Mbps can't be taken out.

A wireless LAN  IEEE 802.11n is made at most 300 Mbps, but when a PC doesn't correspond to a double speed mode, I go out of only at most 150 Mbps.

I bought "BUFFALO AirStation WHR-G301N", but my PC didn't correspond to a double speed mode and was at most 150 Mbps. I was disappointed, but I become 3 times as quick as previous at most 54 Mbps and am satisfied.

 

A double speed mode is to set a frequency band to 40Hz from 20MHz and expand a band, and the speed is made double. A cordless handset has to correspond to a base unit of a wireless LAN, and when BUFFALO AirStation uses a cordless handset of an accessory, at most 300 Mbps is possible.

A double speed mode isn't only a good thing. When it's made a double speed mode, a carry will be half, and when I wouldn't like the electric field situation, speed sometimes falls reversely. At most 150 Mbps which depends on radio circumstances, and is a single mode, speed goes out. When making it double speed, when there are a wireless LAN and a PC terminal in the neighborhood hard, the radio strength is effective. When a double speed mode is possible, I think it's good to try and choose the fast one both.

 

A number as at most 150 Mbps and at most 300 Mbps is the theoretical value to the end, so I think tens of actual condition is Mbps. Even if it doesn't correspond to a double speed mode, I'm out to enough speed, so I don't need to worry about it so much.

Double router release method (bridge continuation method)

The way to do a bridge connection and release double routers.

Release method in detail of the equipment I was using before is explained. I just did using a router of 2 following.

• PR-200NE (modem router  NTT East  FLETS light corresponding to the light telephone  B Flets) 
• WBR-G54 (wireless LAN router  AirStation: air station  BUFFALO: buffalo)

The wireless LAN router (WBR-G54) is made a bridge connection and double routers are evaded.

A bridge connection is the way not to use the router function, to use as HUB and to connect 2 of equipment. It's said that they combine as an identical segment. In other words, it's to make the wireless LAN router the equipment to which a just radio is just transferred.

 

A procedure in detail will be below.

1. A command prompt is started.
2. “tracert www.google.com” is carried out by a command prompt (Even tracert 66.249.89.99 is OK.)
3. An IP address of NTT indicated by "tracert" is noted.
4. The figure of the last limit of the noted IP address is made the price different from other equipment in a modem (100).
5. The cable which is WBR-G54 and is connected to the WAN (FLET’S light  From B Flets) side is removed.
6. In WBR-G54, from a PC, a LAN access (most, port), only, it's done in the state.
7. The network connection of a PC is made a wired connection.
8. Just in case, I insert and remove a power supply of WBR-G54 and make them restart.
9. I access 192.168.11.1 of AirStation(http://192.168.11.1/top.html).
10. An air station setting page is clicked.
11. It's input to a user ID of the dialogue with root.
12. When there is a password, it's input (there is no ordinariness, so, just as it is).
13. An advance is clicked.
14. A LAN port is chosen from LAN setting and it's clicked.
15. First IP address 192.168.1.100 of noted NTT is input to a LAN side IP address.
16. The DHCP server function "isn't used", it's established.
17. A LAN cable from PR-200NE (light B FlET'S of NTT) is connected to LAN port pin of WBR-G54 (the 4th port).
18. A PC is restarted.
19. “tracert www.google.com” is tried by a command prompt.
20. ntt.setup where air.setup [192.168.11.1] cries [192.168.1.1]  When it's 1, it succeeds.
21. A network connection of a PC is returned to a radio connection.

 

When connecting to AirStation of WBR-G54 after setting has ended, it'll be the address established by the above (http://192.168.1.100/top.html). That a port of a LAN access above-mentioned is most, number 4 is used, but which port may it be connected to?

The "its address can't designate the error which is a procedure of double router release and is good. An error occurred by setting. Please redo.", And, I sometimes go out. This can consider that a LAN cable becomes a WAN terminal while being connected as the cause.

 

By the way, new wireless LAN equipment has the function from which you release double routers automatically. When settling it easily, new wireless LAN equipment can buy it, and it's quick to change it, isn't it?

8 reasons that you can replace wireless LAN equipment with something new and buy it

When an old wireless LAN is used, there is a problem like security. The new wireless LAN is very high-speed. It can be bought by these 2 reasons, and I have decided to change it.

Change and buy it, the NO merit was raised 8.

1. The security has been strengthened.
2. Communication speed is fast, Up.
3. Setting became easy.
4. You avoid radio intervention automatically.
5. It corresponds to multi-security.
6. A power saving function stuck.
7. USB equipment of HDD can also be connected, it's possible to share, it was.
8. Double router in case of becomes automatic in a bridge connection.

 

(1) The security has been strengthened.
The cipher form was WEP so far, but cipher of WEP melts easily in now.   In other words, it'll be that the mail contents are looked stealthily at in the neighborhood.   A decipherment tool is also obtainable from the internet.   It's said that WPA2 is safe for the cipher form now.

(2) Communication speed is fast, Up.
It was IEEE 802.11b/g/a so far, but IEEE 802.11n where faster communication is possible was standardized.   Former, it'll be earliness close to 10 times. A figure of speed is different.   At most  54Mbps->  At most 300 Mbps.   In other words, the speed as much as the wired LAN can be secured.  
Maximum path velocity of each standard
  IEEE 802.11b 11Mbps
  IEEE 802.11a 54Mbps
  IEEE 802.11g 54Mbps
  IEEE 802.11n 300Mbps

(3) Setting became easy.
So far, technical knowledge was necessary to connect wireless LAN equipment to a PC.   It can be connected to "AOSS" and "WPS" by 1 button by new equipment.   Really disappointing.

(4) You avoid radio intervention automatically.
The radio circumstances were confirmed by different Tours so far and a channel was established again by itself.   Automatically, radio intervention allocates me a little channel by new equipment.   With thinking nothing, stable comfortable communication can be done.

(5) It corresponds to multi-security.
When connecting more than one PC and game to a wireless LAN so far, all communication has been the weakest security system.   To connect the game to which only WEP is answering to that a PC corresponds to WPA2, I had to lower security.   A security system different in new equipment separately respectively, it could be intermingled now.

(6) A power saving function stuck.
You could put out an LED lamp, lose the rate of the wired LAN and set On of a power supply/Off now at the designation time.

(7) USB equipment of HDD can also be connected, it's possible to share, it was.
It depends on equipment, but there is a USB terminal, and HDD can be connected.   In simple way, NAS can be built.

(8) Double router in case of becomes automatic in a bridge connection.
When it's double routers, communication speed can't do port release, and becomes slow.   New equipment is judged automatically, and you make sure that it won't be double routers.

 

The power saving function and the simple NAS function are incomplete, so I'm so unattractive. But improvement of speed and safety is a big change. I made it a new wireless LAN, too, but when using old equipment, it can be bought and I recommend to change it.

Even if a wireless LAN adapter of PC having within doesn't correspond to IEEE 802.11n, it's no problem. For USB2.0  For wireless LAN cordless handset and CardBus  There is also a product of a wireless LAN cordless handset accessory. Technology is making progress one after another, isn't it?

Confirmation of double routers is a command prompt, tracert .

Confirmation method of double routers. It can be checked easily in a command prompt. When being suspected of double routers, please check it by the following way.
It's explained by a way to WindowsXP, but Vista and Win7 in case of are also operation like most.
First a command prompt screen is taken out. "Program-> accessary-> command prompt of all start->"
Next a connecting path is indicated. When connecting to (tracert) which is a command prompt screen and indicates the process connected to some sites for example gurgling, it's a command prompt.

  tracert www.google.com

It's input and return (Enter) is done. The above?

  tracert 66.249.89.99

Even the above is OK.

  1     3 ms     1 ms     1 ms  air.setup [192.168.11.1]
  2     4 ms     1 ms     1 ms  ntt.setup [192.168.1.1]

Indication like the above comes out. I aim at the last number (the address). "192.168" etc. is a local address, so when 2 are indicated as mentioned above, you can judge double routers. When they aren't double routers conversely, it'll be the name of the provider of flets to be shown to the 2nd.
It's easy, so please try by all means. When they were double routers, release is needed. Separately, I write an article of release method.

When a wireless LAN sometimes breaks, the MAC address is fixed.

Doesn't a wireless LAN break constantly? When using an old wireless LAN router, I think a connection is established by itself. To make sure that friend's PC and iPhone can be connected temporarily, when changing the setting of a wireless LAN, a radio LAN line sometimes breaks well.

You can have cut off correspondeance now well by also making one in case of me a Any connection. After I tried variously, I found out that I hope that you fix the MAC address.

The MAC address can be confirmed by a command prompt (DOS).

A command: ipconfig/all

"Physical address : xx - xx - xx - xx - xx - xx" etc. will be the MAC address in the indicated information.

Many physical addresses come out, so please be careful. Please establish the MAC address of the wireless network such as wireless LAN in case of, a physical address of "Wireless LAN adapter  Wireless network connection" and "Ethernet adapter wireless network connection".

A setting method of the Mack address consult a manual and a home page of the wireless LAN equipment you have, please.

It was settled by fixing the MAC address in case of me. A physical problem and a microwave are sometimes intervening as the other cause. Please adjust an installation site and the direction of the antenna in that case.

It becomes a double router without knowing the change to FTTH from ADSL.

There is a possibility which becomes old wireless LAN in case of and double routers.
But recent equipment distinguishes between double routers automatically and releases automatically.
I also improve security, so when setting is troublesome, it's better to buy a new wireless LAN, isn't it?

When not doing a special thing, the double routers are no problem.
But I think it's better to release double routers as expected.

A PC wasn't also working well in case of me, and when it was checked, as expected, they were double routers.

A router is the communication equipment with which it's connected each other during a network.
Double routers are an Internet access and I say the state that 2 routers exist and are connected to a PC through the 2 routers from outside.
In other words, there seem to be 2 barriers.

There is a possibility which becomes the following phenomenon, setting in case of and double routers.

• A wireless LAN was added from later.
• Communication speed of a wireless LAN is slow.
• It hardens by some sites.
• Trains were changed to FTTH (FURETTSU light premium and B Flets) from YahooBB (ADSL).
• Port opening (port opening) can't be done.
• P2P (Winny, Cabos, uTorrent, Share, Perfect Dark:PD, Bitcomet) can't be connected.
• PSP (PlayStation Portable: Play Station portableness) doesn't get in touch.

It has been double routers because trains were changed to NTT light from YahooADSL in case of me.
There were no problems because there were no router functions for the modem rented on Yahoo! BB ADSL.
To have for the router function for a modem of “FURETTSU light”, when changing it to optical interconnection from ADSL, without knowing, it has been double routers.

Even if a port of 1 router is freed when it's double routers, a port of another router is closed, so port release can't be done.

It was really serious until I arrived here.
Of course, a way of release and the manner of the confirmation of double routers were also checked. Separately, I write an article.

A difference of the wireless LAN BUFFALO AirStation NFINITI WZR series WHR series, comparison

To buy wireless LAN for 11n, buffalo's wireless LAN main phone was examined.
The page has been distributed though the homepage of BUFFALO is seen, and so good doesn't borrow the hoe.
The in one's own way, the specification was confirmed and brought together respectively.

Finally, in assumption of buying the link station
"Wireless LAN router Air Station unit WHR-G301N for BUFFALO leaving power saving 11n/g/b"
It bought it.

In a big reason to choose "There is no USB HDD port", HDD that had it now was uncorrespondence.
When PC doesn't start, the power supply of HDD can be turned off in the link station.
Thus, it does. On/Off is able not to be done at specified time, and to do by the leaving energy saving function of simple NAS this year when the rotation of HDD is stopped though the USB hard disk can be connected, and there is a model that makes it to simple NAS, too.

The chosen reason is that the price is low, and the product is new additionally.

Difference between unit and set

WZR-HP-G301NH/E Cordless handset set Terminal LAN	It is possible to make it to wireless LAN bringing the audio-video equipment equipped with cable terminal LAN and four personal computers together. ｢WLI-TX4-AG300N｣

 
Difference of 301,300

301	The leaving energy saving function has adhered.
300	The leaving energy saving function has not adhered.

The electric rate was simulated for the leaving energy saving function.
About 3000 yen can be saved by assuming that 5W/h can save on the electricity bill the first in five years.
However, I do not think that there is a difference in the amount of money though it contributes when thinking about the purchase price and the use period.

Unlike NH and N.

NH	Cable Giga(1000Mbps)
N	Cable 100Mbps

Difference between WZR and WHR

WZR	With USB HDD port
WHR	There is no USB HDD port

A recent model is truly connected with one button though the setting of wireless LAN was very very before.
It became easy.
