Wireless not working

taisteal

Hi, I hope someone can help me.

On Friday evening the wifi in my apartment stopped working randomly. I connected my laptop directly to the internet cable and it worked fine so I know the problem lies with the router which is separate. I have a Netgear WNR2000 router. I turned it off for a few minutes and unplugged everything and that got it back working on my MacBook Pro.

Unfortunately the other two laptops in the house are still not connecting to wifi properly. The OS's are Vista and Windows 7. It appears to be connected with excellent signal strength but still the symbol displays limited or no connectivity. :mad:

Iphone's appear to be connected with full signal but the internet doesn't work.

I did a factory reset on the router and I still have the same problem. Its working fine on the mac but not a sausage on the pc's or iphones.

Any advice would be greatly appreciated
Thanks in advance

Yikes, sounds strange alright. Have you tried a 30-30-30 reset?

Thanks

No joy unfortunately. The diagnostics on Windows 7 came back with 'The DNS server may be unavailable' Not sure what that means.

hmmm, the plot thickens.

Can you forget that network? If not you could try changing the SSID on the router, although the factory reset may have done that already?

Yes I changed that yesterday and it made no difference at all. It's mad. If it wasn't working perfectly on the mac, I'd have given up long ago. :mad:

That would drive me mental, you could try updating the firmware on the router, but Im grasping at straws with that to be honest, could be worth a shot though.

Any chance the laptops have fixed ips set on their wireless cards instead of automatically obtain ip from dhcp server?

I just checked those settings and unfortunately it's not that either. I'm just ready to give up at this point. It's wrecking my head. At the moment on the windows 7 laptop, the connection is perfect. It doesn't even say the dreaded 'limited or no connectivity'. but it won't work! Google chrome pops up a message saying it couldn't find the address because the DNS look up failed.

I appreciate your suggestions anyway.

Thats a tough one Op.
Of the possibilities, I cant think of anything that would affect multiple devices all of a sudden, particularly after a reset of the router.
Some thoughts, if none of these apply then I am out of suggestions.
If the original ssid was the default one then the ssid after reset would be the same so either manually setup a new ssid and passphrase on the router and/or delete the stored wireless networks in the laptops and try to reconnect as though it were a new network.
Cant be mac address restriction - reset would have cleared that.
Firewall can block http traffic, but how likely is that on 2 laptops.
Proxy server on browser from malware - once again unlikely on multiple devices.
Maybe manually set wireless channel to something other than auto.
When the laptops are connected to the wifi what ip/gateway/dns settings are they getting assigned? - do 'ipconfig /all' from command prompt. Are these settings as they should be and can you ping the dns successfully? Can you manually set fixed ip and dns and does that work?

If none of the above is of any help I recommend a new router and a stiff drink.

have you tried to connect the laptop to the router via cable?

Thanks for all the suggestions. After hours of trying everything, I gave in and bought a wireless modem from UPC.

I still think it was salvageable with more trial and error but I had to write it off for my sanity!

Thanks again
