I have a laptop and a desktop connected to wireless by thomson tcw710 gateway

the wifi connection drops after every 4 minutes saying two or more wireless ntoworks available even i have put mynetwork on the preferred list

kindly guide

Check to see if the internet connection itself on the server computer where the modem / connection to the internet is located, and make sure it is not set to cut off after 4 mins or when no longer needed. Power management also can be the cause, such as turn the Hard disk after so many minutes etc. The problem is likely to be set somewhere in a similar manner.

Good Luck

have a same problem, conn drops/giant lag spikes every few minutes .. annoying

Has anyone solved it? Cause I've got the same problem and it's really really annoying I have to unplug the modem and then plug it in agin

Two possible culprits: wireless phones and neighboring wifi APs/routers.

Changing the channel on your router might help. Moving the router or using directional antennas might help, too.

Buy the most huge stupidly ridiculous antenna you can find and place it in the sky. this will gt 1000% connected

go on ebay and buy a yagi 19dbi antenna or go to maplins and buy a hawkings 15dbi antenna.

If the Antenna on the Router is detachable replace it with a higher gain Antenna and do the same the PCI card on the desktop, the laptop might be a bit tricky although they are N-range PCMCIA cards you can use with a good coverage,

Good Luck

dkdutt,
I have worked with a few routers in my time but never a thomson tcw710, so I dont know how good they are. What I recommend you do is go on their website normally they have a Driver/Support page, download the latest firmware for the router in questions and hopefully this will solve the problem of intermittent connection. If this does not solve the problem contact your ISP they can ping the Router to check connection.

dkdutt,
Some good suggestions have been posted. If the outage occurs every 4 minutes it seems too regular to be something random like a cordless phone. What you really need to do is do a site survey. Unfortunately, most site survey is done with a 802.11 client so other signals like cordless phones, microwaves, and other transmitting devices don't get picked up. Nevertheless, at least see if there is another powerful wifi signal nearby. Then you can play with you channel selection to move to a different channel.

You can also try a directional antenna. My recommendation would be a panel or a grid, they're ugly but they have high gain. The high gain will give you a narrower beam which could also help isolate interference.

Sometimes the noise figure in the environment may just be too high. Moving to a higher frequency, say 5Ghz could move you out of the interfering band.

Good luck..........RFengr
