I will be extremely grateful to anyone who can help with this. I'm not sure I can even describe this problem, so you helpful folk out there may have to ask me some questions. I'll try my best.
I share a house with other students, we have a Netgear wireless router and a Virgin media cable modem. Until recently, all problems I've had with connectivity have been resolved by turning off the router, counting to thirty, and turning it back on again. But a much weirder problem has developed recently. I'm sure the fault is with my laptop (the other two computers here are unaffected, and I am using the correct SSID), but I can't isolate it.
The laptop in question began giving the message "limited or no connectivity" about a week or so ago. The IP address is assigned dynamically and was coming up as the 169.154. etc autoconfig one that cannot access the internet. I tried moving the laptop around the house, nearer to the router for example, and it did not solve the problem. Then the problem seemed to disappear as if by magic, and I had a connection to the internet, but a strange one. In the "view available wireless networks" window, the green bars indicates a good signal strength, and in the text I am told that "you are currently connected to this network", but the larger text in the top-right (above the signal strength bars) remains as "Not connected". And, this connection kept being lost, and I had to reconnect many times during a session online.
Now the problem has developed to the stage that I am still given conflicting messages about the connection (as described above) but both browsers I have (Firefox and IE) do not display webpages, just as if there was no connection at all.
I have tried using a static IP address (192.168.1.7) which again indicates connection to the network but no access to the internet at all. I connected the laptop directly to the modem with a cable, which solved everything - but this is not a practical solution as the router is in the hall and my room is upstairs.
Any help will be hugely appreciated!
