Limited or no connectivity to wireless router?
I am having a problem with two laptops on the wireless network. Each one of them show a "limited or no connectivity" message even though the signal strength is always good. The router is working because I have a desktop that connects directly to him, and the Internet work for him. I have tried to release and renew the IP address on the laptops, but always says it can not renew it. The drivers are all up to date for the wireless card, so it's not that either. I tried to ping and powercycling in vain. At the command prompt, also says it can not connect to the DHCP server. I do not know how to fix this problem and has sought answers, but I can not find any. I would appreciate any help anyone can give me before resorting to ask Dell or Comcast to help, since they are not the best people in the world to treat.
What type of router is it? How often? How computers are now portable router? Do these laptops connected to the router in the past? Do you have a cordless phone at home and if so how often? What your neighbors so close to home? Do you know if you have a wireless router at home at the same frequency? How about a cordless phone with the same often? My first suggestion would be to change the channel on the router's configuration and the attempt to connect to the router wirelessly with the laptop sitting right next to the router. Try to see if it can be discarded if it is some kind of radio interference found.
