    Hi all. I'm at my wit's end trying to fix my wireless network, so I thought I'd call in reinforcements.

    I've got a Realtek RTL8180 wireless card in my PC. It's upstairs in my house, probably about 50 ft away from my Netgear wireless router. For about 8 months, this arrangement worked just fine. My connection wasn't the best in the world, but it was routinely 80% signal strength and above, and transfer speeds/latency were not significantly different from the wired connection.

    All this changed about 1 month ago. My signal strength plummeted, and it now bounces around (it oscillates wildly, even) 10% to 40%. It is particularly bad when the computer is first turned on; the card usually can't even pull an IP. About half an hour later, I can limp onto the network. From then on, using the internet is a painful experience. Page loads take a minute or longer, if they happen at all.

    I've tried every possible antenna orientation I can, no go. I've checked for any new wireless networks that might be interfering; there are none. I've tried different channels.

    My brother's IBM laptop with built-in Cisco card works perfectly in the same room as my box, so I'm sure it's the card in my box that's the culprit. However, like I say, it worked just as well up until recently.

    What could cause such a sudden drop in performance?

    Incidentally, if this is useful, I picked up some stats from the Realtek Utility. It seems the ratio of Rx Retry / Rx Okay is about 1, while the ratio of Tx Retry / Tx Okay is about 10.

    I would recommend trying a different card... Realtek isn't really known for quality. It wouldn't surprise me if it was a bad card.

    Aye. If no one has any brain waves, I'll probably order this: http://www.newegg.com/Product/Product.asp?Item=N82E16833130111

    I can't live without the internet, and what's $30 compared to therapy?

    If you introduced any new electronics in your house recently that could also be a problem. Certain things can cause interference with wireless.

    Hey, I didn't recommend anything other than a new card. I didn't at all say that it was a good or bad one.
