I have two laptops SOny vaio VGN - CR220E and Dell Inspiron 1525. I'm using high speed Internet of ATT. Modem: 2Wire Gateway (4200-001047-001) RG2701. The wireless router is linksys rangeplus wireless router WRT110.
The first time I finished installing the wireless router into my computer and did all the steps correctly, I could not use Internet. Thanks to the technician of Fixya, I can use Internet by changing the IP add 192.168.1.1 into 192.168.2.1
However, sometimes I can not access Internet. I press "diagnose and repair network" tab and it said "can not communicate with the DNS 192.168.2.1. or send to the host but not receive a response".
I don't know why and don't know how to resolve it. Please help me. Thanks
