I have a D-link router set up about 3 meters from my laptop. There are periods when I get disconnected like 6 times a minute. If I set up WEP encryption it gets even worse and speed is so slow I can barely access in order to disable WEP.

The disconnections seem to stop when I change the channel setting. Sometimes selecting channel 6 helps. But after a while, the same things happen with channel 6 so I select another channel, like 12 and so on.

Is there anything I can do to make the disconnections stop permanently?

What router & firmware do you use? How many other WLANs are in range of your router? Do you encounter these problems only at specific times let's say only in the afternoon? – nixda Jan 1 '13 at 16:41
its "DI-524". if by WLANS u mean other wireless networks, there are like 6 besides mine. Disconnections started a few minutes ago, but I changed channel and they stopped for now.. – Anna Jan 1 '13 at 16:46
please edit your title to match your problem – Matsemann Jan 1 '13 at 16:49
What wireless protocol are you attempting to use? Wireless-N (802.11N)? I've had a lot of problems with -N and it's router & computer specific. Some computers will work fine, while others won't with a particular router, whereas the same computer will work fine using a different wireless-N router. – slm Jan 1 '13 at 16:51
I'd suggest a firmware update but the dlink site shows that the latest firmware version is from 2004 (wow). That router has mediocre reviews as it is, and a lot list intermittent connectivity issues. I'd suggest you just go ahead and invest in a newer N router. No amount of troubleshooting will make up for a bad product. This isn't an answer to your question really, but it's the best advice I can offer. – trpt4him Jan 1 '13 at 17:37

The DI-524 was introduced about seven years ago as a low-end, low-cost router. You can get mid-range, dual-band routers for around $50 now. It's definitely time to upgrade.
