EDIMAX BR6104K Fast ethernet Broadband Router. (all lights lit correctly)
Windows XP pro
VIA Rhine II Fast Ethernet Adapter
Motorolla Surfboard SB4100 cable modem
Zonealarm free firewall

I had this network up and running with a 4Mb Virgin Broadband connection, wired to another pc through the router. Worked fine but a bit slow. Upgraded to 20 Mb connection and also done clean reinstall of XP. Internet fine direct to primary PC from modem, but cannot get xp to recognise router. I.E cannot enter router configuration through web browser. ( IE6 or Firefox).

DHCP enabled. TCP/IP properties dns and IP address set automatic.
xp will not allocate default gateway , router IP address.

I,ve struggled with this for a while now and tried inputting network configuration manually. IPCONFIG /ALL recognised manual default gateway but still couldn't enter router configuration. Any pointers much appreciated thanks.

A short, focused isolation plan that builds on ’s troubleshooting: aim to determine whether this is a LAN-address conflict, a physical/cable/port issue, an XP/network-stack problem, or a router firmware/hardware fault. Work through the steps below in order — each one rules out a whole class of causes.

  1. Isolate the router from the modem and other devices. Power both down, disconnect the modem from the router’s WAN/Internet jack, then connect only the PC to any LAN port on the router. Confirm the NIC link LED lights (try a different cable and LAN port if not). Assign the PC a static address on the router’s private subnet (pick an unused host number, mask 255.255.255.0) so the PC and router are on the same network even if DHCP is not responding. Then try to reach the router’s LAN address printed on the device or in the manual.

  2. Quick XP checks while still isolated. From XP check Device Manager for the NIC driver (reinstall if suspect). Temporarily disable ZoneAlarm/any other third‑party firewall, and make sure no HTTP proxy is set in the browser. Use simple network diagnostics: ping the router address, arp -a to see if a MAC entry appears, and run ipconfig /release then ipconfig /renew to refresh leases. If the router replies to ping or appears in ARP, the web UI is a browser/config issue; try a different browser or clear cached settings.

  3. If you still can’t reach the UI: perform a hardware reset on the router (use the reset button per the device instructions — hold the button long enough to trigger factory default). After reset, with modem still disconnected, reconnect the PC and access the router to change its LAN IP to a different private subnet to avoid conflicts with the modem. Remember a factory reset clears saved ISP/PPPoE settings.

  4. Final checks: try the router with another PC or a Linux live USB to exclude Windows-specific problems. If the router remains unreachable after reset and isolation, firmware corruption or hardware failure is likely; at that point RMA/support or replacement is the practical next step.

Post ipconfig /all
The router default page is 192.168.2.1.
What's the default modem address?

It looks as though the modem and the router share the same default address. ()
Change the router address. should do it.

Member Avatar for mand898

do you mean manually input the addresss as the default gateway in TCP/IP settings. Sorry to be a bit dumb here. No combination of the above address entered into my browser will connect to the router page.

This has to be changed in the router configuration page.
See page 25 of the manual, and change the default Lan IP address.
The manual is here:

After this change, the gateway should show as whatever you select, such as

As previously posted my problem is that I cannot enter the router configuration page to alter any settings. Entering the default router address in my browser doesnt get me to the page. Thanks

Reset the router to defaults and try again.
If you still can't enter the page, the router is faulty or your firewall is blocking you.
