Hi,

I would like to ask anyone for help. My wireless connection was perfect until yesterday when it suddenly stopped. I have laptop HP 6720s with Windows 7. I can still see the list of wireless networks and when I try to the preferred one (which is public and would normally take me to me browser to log in) now it just says 'windows was unable to connect'. I tried many advices but it still doesn't want to connect. Also, when I tried the second preffered option, that one wouldn't connect either. Switch is on and it is working. My other connection (on USB dongle) is fine. Please help anyone! Thanks

Okay, then the first choice that I would do is to delete Network A and B, restart and let your laptop rediscover them then select your choice. The MAC address alone will probably not fix it since you need to flush the old network data out by deleting them.

So you have two wireless adapters using different networks or the same network?

With multiple adapters (wireless and/or wired) you should only be using a gateway address on one of them.

First I would go into the network control panel, select manage wireless networks, and delete the networks, then restart your computer and allow it to find them again and then attempt to logon. This commonly helps if you use a lot of different networks like traveling and using hotel wireless.

Another thing that often helps is to change the MAC address of the problem adapter using the free tool from HERE as that often fixes that sort of connection issue. It will save your old MAC address.

Thanks for the reply.

When I go to the library I have the option of two different free public networks. I have only one wireless adapter on my computer and usually I choose network A. When A is not working I try B. The thing is, since yesterday A wouldn't even start and B would say it's connected but there is no connection actually. I changed the MAC address and I will let you know tomorrow if it worked. Thanks!
