In our office in London, which is part of a business center, we decided to replace our D-Link DI-804V VPN router as for some unidentified reason it seems to reboot itself every 27 minutes, loosing and reconnecting the internet connection each time. We bought a Linksys WRV54G a few days ago and I have been trying to install it ever since, and failed. I set it up with the same details as the D-Link one (Same WAN IP, Mask, Gateway, DNS servers), disabled the firewall, static routes and port forwarding and physically connected it to the LAN switch and to the WAN cable taken off the D-Link router) Most functions seem to work, ie. all computers receive a DHCP-allocated address and all computers on the local network can talk to each other happily. However, we just cannot get an Internet connection. From any machine, I can ping the LAN IP of the router (192.168.120.1), its WAN IP (10.10.6.1) but thatâ€™s it. Any address beyond that returns a â€œDestination net unreachableâ€ error. If I put the D-Link router back on, it works fine. Linksys back on and again, no internet connection, although the router itself says (in its web-based status page) that the internet is connected, and the WAN Link/Transfer LED on the router is happily green. I upgraded the firmware to 2.37EU but that didn't solve the problem. I tried this router at home, and connected it to my DSL line and had no problem there, with the exact same settings (apart from the WAN IP and gateway obviously). Internet connection was working fine from any machine on the home LAN. Do you have any idea what the problem could be. Could it be a hardware problem between our router and the business center one? Any help would be greatly appreciated.
