What are the indications that clients are seeing the old router? Did you configure the new router with the same IP as the old router? Or, if you did not, configure it with a new address and test access and then remove old router and give old router IP/name to new device? The clients do keep old wireless connections listed. They will need to be manually cleaned out. The best option would have been to configure the new router EXACTLY the same as the old one. Then the transition should be transparent to the users. Check the channel & SSID settings too. Maybe the clients are set to look for specific channels. The recommendation is to use channels 1,6, & 11 as there are no frequency overlaps. ********************* If your clients are getting the router or gateway from DHCP, check that the option in DHCP point to the correct device. On the clients, you can do a repair on the interface to flush data. ********************* If you clients can connect to each other,and network resources like printers, but are unable to connect to the internet make sure that the gateway setting in each computer is correctly configured. In most cases the gateway address is the same address you use to access the router's web client. For linksys the default is usually 192.168.1.1 ********************* With my experience when working with routers/modems/NICs a complete uninstall and removal of previous software is necessary when upgrading. Uninstall COMPLETELY, and then install the new device. Even so, the devices accepting the signla might not be communicating on the MAC address level to know that the sending device has changed...the above options all seem like reasonable solutions as well. Hope this helps! -Schmidtw
