Help! I'm having a majorly annoying issue with my wireless card. About 6 weeks ago my family got a new wireless router and DSL modem (all in one, Netgear) from AT&T. (Our old DSL modem had bit the dust because it had been dropped several times and the case was cracked open.) With the new router/modem, my laptop was experiencing frequent drops of the wireless signal. The wireless would drop then reconnect every 5-10 minutes. I tried many things to fix it, including setting a static IP on my laptop and changing the channel on the router. What finally seemed to fix it was to switch from the default "Mixed 11b, 11n, & 11g" signal to "11b only". I no longer have the dropped signal and the speed has improved.
However, in the past week, I've had a new problem pop up. When I first boot my computer or after waking from both sleep and hibernate, the wireless won't connect. It is almost as if the card is turned off/disabled, as in the system tray, the wireless signal icon shows with a red X, and the message when I click it is something like, "No wireless networks available". I click "troubleshoot" and results will show "Problem with wireless adapter or access point" and "Windows can't connect to the hidden network". I then click through to complete more troubleshooting steps. It will show that it is resetting the wireless adapter. The wireless icon will briefly show the available networks, and I click on my home one to connect. Then it will blink out and show again that there are NO wireless networks. Stepping through the troubleshooter again, I tell it to skip several steps (sorry, can't remember what they are) and then the wireless will miraculously come back to life and connect like nothing is wrong!
I don't know whether it's the troubleshooter or just time that is resolving the issue, but this happens EVERY time I turn on my computer and takes 4-5 minutes to get the wireless card up and working again. I should also say that I was having some other weird behavior, so I've been doing lots of scans and other troubleshooting in the past 2-3 weeks. Spybot Search & Destroy found a few spyware problems, including Widgi Toolbar, Yontoo PageRage, and Tarma Installer. A Google search revealed that one malware had the possibility of keylogging (it was displaying blue underlined links to ads.) Multiple virus scans have revealed no further problems.
Any idea what may be going on?? Sorry for such a long post, just trying to be thorough in describing the issue. I'm usually pretty savvy and able to solve most computer issues but this one has me stumped and frustrated!!
