I am experiencing connectivity issues pretty randomly on one of my laptops (other devices seem to be working fine).

I've done some troubleshooting but so far, no definite answer to what's causing this. Here are my specs:

System: Win 8.1

Adapter: Ralink RT3290 802.11bgn Wi-Fi Adapter

Wireless Router: R1000H - Wireless N Gigabit Ethernet Router

I've checked the following:

  • checked whether IP4 obtains IP automatically
  • pinged default gateway, sometimes I get two timeouts and then I get connected
  • disabled power saving mode (Allow the computer to turn off this device to save power)

Any tips how to resolve this would be greatly appreciated.

Thanks in advance! :)

Can you add some more detail regarding the symptoms you're experiencing? –  Bradley Forney May 7 at 5:02
    
Hi Bradley, I often see that I am "connected" to the network but when I try to load a page, I am unable to connect. Sometimes I see that I am connected to the network but the status is "limited" - no internet access. As I said it's pretty random. I can work online for an hour and then the connection drops. When I try to reconnect (sometimes) networks are not even picked up for a little bit. It makes no sense to me. Any suggestions would be greatly appreciated. Thanks! –  BustedSanta May 7 at 12:05

Since this seems to be isolated to just one device I'd suggest seeing about buying or borrowing a USB wifi adapter. If that works without any issue then it may be that your existing wifi adapter is failing. If you still have the same issue then it's most likely something going on with that specific computer.

One thing you can try is download a tool like inssider or netstumbler and get a look at the channel usage in your area. It could be a case where other routers in the area are all operating in the same area, causing interference. If you see this you can change the router's channel to something less populated. However, given that this is isolated to one device only I suspect this isn't the case here.

Using those tools you can also see signal strength. You can use that to see if maybe you're just in a bad location for receiving a good signal. The usual culprits for interference are strong motors (like in elevators), electrical panels, solid layers of construction (like a brick chimney), and so on. But again, I suspect this isn't the case given the isolated nature of the problem.

Good luck!
