Wireless problems - up down up down up down

Satsumomo

Hey there guys!

I need some help pinpointing what is causing my connection to look like this: (My SSID is W32.Winvirus)



So many big jumps, and why do other hotspots always show up as huge spikes like that? I'm definitely changing this horrible TP Link wireless adapter I've got on my desktop, but I'd also like to know is if these other connections doing huge spikes are what's causing trouble on my end. I don't have any other wireless devices in my apartment, and the router is about 25 feet from my computer, goes through 1 thick wall.

Thanks.

Why did you choose channel 7? Outside of weird circumstances caused by other people using dumb channels you should always use 1, 6 or 11 to prevent overlap like what is slightly happening currently between you and the INFINITUM5f23 network which probably isn't causing problems but your better off avoiding the issue to begin with. On that note you should switch to channel 1 since the only network using that band is weak and if the yellow network spikes aren't glitches then you've also moved away from any interference that it might be causing.

I chose that channel because I supposed it was the way of avoiding all that damn interference.

From what I read, 2.4ghz phones use channel 0-2? Not sure. What bothers me the most is that if I so much place my computer 1 foot more into my room, my signal dies and becomes pretty much just as strong as these other networks.

I'm using a D-Link DIR600 router, with dd-wrt firmware. TX power is set at 84. I don't get how networks that are on completely different and much farther spots have such a good signal to my computer.

You aren't avoiding interference as the graph you posted shows, and a lot of phones at least when I checked hopped around the 2.4ghz band instead of staying on a specific channel. Just looking at the graph channel 1 is the best option and then kind of a toss up between channel 6 and 11 since the yellow network on the graph looks like some sort of glitch, but you can switch between them to test. You really shouldn't be losing connectivity by moving a foot, but with wireless network interactions basically anything is possible and your best bet is to either move the computer or the router preferably in the same room, but just moving them around may help.

It's not just the yellow connection though, at least 2 other connections (Valdosanp and others that didn't show up this time) have those huge spikes. Could the spikes be glitches on my wireless card and not actual spikes from those networks?
