Bad wireless lag spikes, overheating possible?

[Westify]

I just recently bought a new wireless card, it works great normally, 4 bars in windows, 90% signal strength from the router, working great.

However it seems that on warm days i get terrible lag spikes, it effects downloads,. gaming, streaming music, everything really so i know its an issue with the wireless and not an issue with a program itself.

I've checked everything else in my house and no there's no other interference going on at that time, i just think its really odd that this could be a heat issue, i've never heard of that before. Room temperature is around 73'F here and i posted a screenshot of my temps during a 60% load below.

I'm just wondering if its actually my wireless card itself overheating or something else on my computer like motherboard chipset or CPU, in terms of hardware my CPU is an AMD x2 939 3800+, MB is a DFI NF-4. and the wireless card is a Rosewill RNX-N300X

It could be a lot of things, first thing I would suggest you check is that your router is set to a single broadcast channel, I have come across people having lag problems when their router keeps changing channel due to interferance from another router almost out of its pickup range.

As for overheating causing lag spikes I have definatly seen this happening before but only in laptops how good is your airflow in your case and is something venting warm air onto the wireless card?

I have auto channel scan turned off and am just using 1 static broadcast channel (9) if that's what you mean. I also enabled auto 20/40mhz channel width opposed to just 20mhz as instructed by somebody when i recieved this new card to get the max bandwidth possible, not sure what that really does

As for my case airflow i have the side panel off so it it i imagine it shouldn't be that much of an issue, only other PCI card that's close to the wireless adapter is an old sound card, i doubt that generates much heat.

wireless is not the best for gaming.and do you have a password on router to make sure no one is taking your connection.

Dennis....i'm going to take the highroad on this one

I'm aware its not optimal for gaming but its what i use, these lag spikes are not "normal wireless" they did not occur in my old wireless card at all, unfortunately it was only wireless G so i needed to upgrade to a faster N card.

And yes my network is secure
