Been having trouble with my computers wifi card SINCE I got it 2 weeks ago. The COMPUTER is a PRYON FX6A, and the wifi card is a 802.11n wireless LAN card made by Realtek. I am running a registered version of windows 7. When this problem first arose I took it back and the guys I brought it from uninstalled the hardware and reinstalled it. Is this just a quick fix or if I do it again will it work for good? The card then started playing up again last week and since then has been playing up, it wont connect to the internet at all at the moment and when it does the card then somehow disappears from my computer and it can no longer pick up my wireless network. Is there something else I can do to solve this problem other than what has all ready been tried.
Also it has nothing to do with the router or network as i am using my iPod to create this post on the same network I am trying to get my comp to connect to. Does the card actually disappear from hardware manager or is it just having trouble keeping the connection?

If it's just the connection, go into your wifi router's settings, and try CHANGING the channel it operates on. Other household electronics use the same frequency range as wifi does and can cause interference. These items can range from cordless phones to microwave ovens. This interference can sometimes cause signal problems for wireless devices. Just because your iPod works ok doesn't necessarily mean there isn't a problem with your network. Interference has different effects on different devices.

Anyway, look at your current channel and either add or subtract 4 to the current channel. For example, if it's channel 1, try channel 5. If it's channel 5, try channel 1 or channel 9, etc. (if you're using 802.11g). If you're using 802.11b or 802.11n, change it instead by 5 or 8 channels respectively.


Technical Explanation: (not necessary to fix your problem, but will explain in more DETAIL)
The usable 2.4GHz range used by wireless devices ranges from 2400 MHz to 2483 MHz. Since each 802.11g channel covers a range of 20 MHz (10MHz in either direction from the channel's actual frequency) but each channel is only 5 MHz apart there sometimes is overlapping that causes interference. When adjusting by 4 channels, you're choosing a new channel that doesn't overlap with the previous one at all.

If on the off chance that you're using 802.11b, move 5 channels away instead of 4. 802.11b channel width is higher than 802.11g/n. If you're using 802.11n, then you'll want to move 8 channels away as 802.11n channels are twice as wide as 802.11g/n channels.WOULD the channel be the transmit buffers?The channels would be the channels, I've never known them to be referred to as anything else. You can find it in the WLAN or WIFI or Wireless settings for your router. Don't confuse these with WAN, which has nothing to do with WIFI.
