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.
