You have a Linksys Etherfast Cable / DSL router and are having problems with:
You can also try the Linksys Support page and Tech Helper for the router, or contact Linksys support via one of the following methods:
If you follow the setup instructions in the Etherfast manual in the order that they're written, you might not be able to connect with the built-in administration webserver at 192.168.1.1. If the login box doesn't come up when you type 192.168.1.1 into your browser location box, and you have Link lights at both your NIC and at the router port that the computer is plugged into, it may be because of your TCP/IP settings.
The easiest way to fix this is to let the router's DHCP server handle setting up your Client computer's TCP/IP. Do the following:
The Remote administration feature added by the 1.30 and higher firmware allows users located on the WAN to reach the built-in administration pages. To use this feature, you enable it on the Filters page and then reach it by using the WAN IP address plus ":8080" added to the end (without the quotes).
Example: If your WAN IP address is 126.96.36.199, then you would enter 188.8.131.52:8080 into the browser location window.

The following was contributed by Martin Weigand:
My provider is Charter@Home in Upstate SC. This setup process is easier if you have more than one machine, as you can keep your existing unit configuration unchanged until you have established the new connection via the router. I spent 5 nights with my project before calling Linksys Tech Support, and was about convinced there was something unique with our provider (Charter) that would prevent me from using this unit, but I was too stubborn to quit. The following hints may help your installation go easier.
1) Get some information
2) Get rid of any Proxy settings
3) Cycle the power
4) Use DHCP
5) Configure the router
That's about it. Once I got my first system "online", it took all of 10 minutes to make changes to my other systems, reboot and customize the settings.
Having trouble getting a DHCP address from your ISP
NOTE: You may be able to avoid having to call your ISP to register your new MAC address. See this page.
Some ISPs use the Adapter (or MAC) address of your NIC to enable
service (MediaOne/RR in the New England area does this, as does Prestige.Net (Carroll County
Maryland). If this
is your situation, you'll need to follow your ISPs
procedure to register a new address, but using the router's MAC address. You can find the address on the
router's Setup page listed next to WAN IP Address,
and titled MAC address. (It looks something like
1) After you call in the address, unplug your cable modem power and unplug the router power. Wait about 5 seconds and plug in the cable modem and wait for it to boot up.
2) Now plug in the router power, & wait for the router to finish starting up.
3) Check your router's Status screen and look to see that there is a WAN IP address and valid DNS servers listed.
4) If you don't see the IP info in #3, reset the router or
force the router to do a WAN DHCP renewal.
5) If you did get valid IP address info, start your web browser and see if you get your normal start page.
6) If you don't get your browser start page, you may need to reboot your computers, or run winipcfg and do a Release/Renew on your client's Ethernet adapter before you can access the Internet.
Hangs, garbled webpages, corrupted download files, and other strange behavior
Reports of problems continue, although many users do not experience any data corruption problems with the router.
Here are things you can try:
1) Upgrade the firmware if you already haven't.
Make sure that you have a solid connection
to the router (check this by pinging the router multiple times) before
trying to upgrade the firmware!
2) Try forcing your NIC to 10Mbps or half duplex mode, and turning
off the "Autonegotiate" feature of your NIC as a temporary measure.
3) Make sure you do not have devices plugged into the Uplink and Port 1 connectors at the same time! This is easy to do, given the way the connectors are laid out. Use only one of these two ports at a time!
4) There is some evidence that you may have problems if you have altered MTU settings or run "speed tweak" programs on computers that you connect to the router. This page has information on restoring the proper settings.
5) Try getting an exchange of the router.
Please let me know if any of this helps, or if you come up with a solution!
Updated 4/3/01 Getting your NIC to work
There was a problem with the built-in switch and some NICs, including Linksys NICs. Symptoms include:
Linksys says that they've resolved this problem. If you are having a problem getting a NIC to connect to your Linksys router, either try the Tech Helper, or contact Linksys Tech Support for help.
NOTE that you can't determine whether the cable is ok by "buzzing out" the cable, i.e. testing electrical continuity. The Transmit and Receive connections must each be in their own twisted pair of wires, and unless you have a transmission quality analyzer, you have to look at the color coding. Each twisted pair is denoted by the Color, Color/White stripe coding.
If in doubt, go get a good, name brand patch cable, i.e. Belkin, Belden, etc.!
Setting it up with a Mac
If you're having trouble getting a Mac to connect to the router, you can get help for setting up TCP/IP on a Mac starting on this page from ATPM.
The Macfixit site also has some good Mac-specific setup info, including getting the router to peacefully co-exist with an Airport base station.
7/5/00 You can also check out this thread on the MacFixit forum from John Strung.
Also upgrade the firmware if you already haven't.
Changing the WAN MAC address.
Version 1.37 firmware moved this function to its own tab. Click on the "Advanced" tab, then the "MAC Addr. Clone" tab.
Can't find this feature in the 1.30 to 1.36 higher firmware? Just look at the screen shot below!
This feature may not work from a computer that is running Norton Internet Security. In order to get it to work with NIS 2.5 you must allow script popup windows to run. This is done in the advanced options web settings of NIS. [Thanks to James Grove for the tip!]
Problems with PING and TRACEROUTE.
Version 1.22 and higher firmware adds a "Block WAN request" feature to the Filters page. If this is enabled it will block all ICMP requests, which both PING and TRACEROUTE need, and you will not be able to get a response when you PING or TRACEROUTE the WAN side of the router. Just DISABLE this option to fix this.
Restoring a missing STATIC ROUTING page
(BEFSR41 model only!)
If the Static Routing page on your 4 port Linky goes missing (sometimes after a firmware upgrade), do the following:
1) Download this file (befsr41_boot.bin)
3) Use the Linksys upgrade utility to load the befsr41_boot.bin file into your router, just like you would with new firmware.
4) Remove power from the router. Wait 5 seconds or so and reapply power. (You can also try just hitting the Reset button instead of doing the power cycle.)
5) Now load (or re-load) the desired firmware into your router. If you've changed the password from the Linksys default, you may need to enter default password (admin) for the upgrade. The Static Routing page should now be restored.
If you have problems (router locks up with a flashing Diag light, password keeps getting rejected by the upgrade utility, etc.) use the Dead Linky hints.
