Hi all.
I have a TP Link  Wireless N Modem Router (model TD W8960N)
Computer is  a Dell running Windows 7
The computer uses a  TP Link wireless N adapter to link to the modem/router

I set up the modem/router with an ethernet cable between it and the computer. This way, I created the wireless network and enabled access to the internet via my ISP settings- all good so far.

Then, undoing the cable, the wireless adapter seeks and finds the wireless network, I sign in and it all works fine...some of the time.

the same setup with an older Linksys modem/router (same TPLink wireless N adapter) has no issues at all.
this is the second TP Link modem/router I have tried, same issue!

what happens is, the internet connection disappears intermittently for a few minutes- 
the network disappears from the list of available networks and then magically reappears.
it effects access for all devices in the house- so it is not just the wireless N adapter.

I am at wit's end trying to sort it out. 
in the course of writing this email it has dropped out 5 or 6 times.

any suggestions?
is it an incompatibility somewhere?
is the connection from pole to house too weak or noisy to support the router's demands, so it just throws up its little hands in horror??

thanks for any comments... Theo

More likely some interference in the channel. Do you have any cordless phone being used around it, microwave ovens? Have you tried changing the channel setting in the WiFi access point configuration? Tried changing the transmit power?

yes to both- microwave and cordless phone, neither were in use at the time.
the phone is supposedly interference free, but I'll try changing as suggested.

thanks!

If the problem gets worse then i would focus on finding a location with better coverage for the wifi router. Normally they say to use either channel 1, 6 or 11 because other channels overlap and could suffer from more congestion. Don't worry about the cordless if its a 1.8Ghz phone because wifi uses 2.4Ghz.




Time to find a new industry!

If it's Uniden, ignore that. I've done some testing with an "interference free" Uniden phone which was marketed as being 5.8GHz and therefore won't interfere with your Wifi.

Problem is, some quick spectrum analysis showed it used 5.8GHz for the Base -> Handset path, but random-channel 2.4GHz for the return path.

Most other cordless phone vendors just use DECT which is 1.8GHz so shouldn't cause problems. Still don't recommend having them sitting right next to each other though.

thanks all.
having assigned the channel (i.e. not the 'auto' default) things appeared to have settled down.  I do have the Uniden phone- but it is DECT, although the base station is the other end of the house. WIFI reception wasn't the issue, as the modem/router is on the other side of the room from the computer,and signal strength was fine everywhere. 
so, unsure if dropping the power to 80% had any effect- I might try plating with that. 
thanks again for the thoughts and suggestions. Theo

FWIW My girlfriend has a Dell on Win 7 with the same issue - signal strength (when it sees it) is good, between 75 - 80% with a couple of walls in the way.  Then it intermittently drops the signal for no reason (no microwaves, etc.).

Have you updated the Dell wireless drivers?  Seems to have fixed it somewhat.

Using auto for the channel is known to cause problems where there is a lot of interference, worse using N and 40Mhz mode.  The disconnects happen when it changes channel due to interference.

Hence, fixing the channel is probably what has helped here, FWIW.

Install InSSIDer and look for the channel with least signal, then set that.  Also try disabling 40Mhz mode (set to 20Mhz only) unless you really "need" the high speed wireless.

great- thanks I'll try all that and get back.
what would be the speed diff between 20 and 40?

20Mhz (theoretical) is up to about 150Mbps, 40Mhz to 300Mbps.  

For accessing the Internet, you don't need it because ultimately the performance is limited by your internet connection.  Even locally it probably won't make a huge difference.
