Hello,

I had a weird situation at work the other day. Here's my setup : We are running on a T1 line supplied by Local Bell which goes through a CSU/DSU, then to a Cisco Router, then to a Cisco Switch. I had installed a Linksys 8 port (DHCP enabled) wired router with a 5 port switch (to expand the number of runs) so that I can supply my tech room with multiple access points to the internet. Usually when a customer asks us to verify/configure a router, we just connect the customer's router (from the WAN) port to one of the network connections in the tech room. Since my linksys router has DHCP activated, the customer's router is able to get an IP as if it was connected to an ISP enabling me to verify it's working properly and I do my usual tests like connecting to the internet with the customer's PC. I've used this setup for over 2 years. I never had problems connecting Netgear, 3COM, Linksys (BEF ?? wired series ) and SMC (old wireless) to my Linksys but I encountered a weird one with the 2.4 Gig wireless one from Linksys. Somehow, when I connect the 2.4 gig to my Linksys, it's to get an IP from the DHCP server but I can't connect to the internet. I'm able to get the config page to verify the status of the connection, I even tried settign a static IP on the customer's router. At first I though it was the customer's router that was busted so I went on the sales floor to get a second one, still no go. I decided to upgrade the firmware and it was even worse. During the upg, somehow, the 2.4 gig router lost connection with my computer rendering the router useless because of incomplete upg. I redownloaded this and tried it on the second router, same thing... Now as this point I got two dead 2.4 gig routers. I then went to get a third 2.4 gig router but this time I decided to connect it straight to my Cisco switch (bypassing my own Linksys router) and WOW it works. Somehow, this 2.4 gig wireless doesn't like to be daisy chained to another router... I didn't bother calling Linksys tech support because I was glad it worked but I found it strange... Anyways, what are the chances a customer will actually have two linksys routers daisy chained. But anyways, this message is FYI to warned you in case you encounter a similar situation (I spent around 2 hours). If I have time, I'll go grab another 2.4 Gig and do some more tests and posts my results...

see ya

The issue is well known.

The safest way to upgrade the Linksys firmware is to have only 1 computer connected to the device directly.

The computer will should use a static ip. As the router by default is at 192.168.1.1, an ip of 192.168.1.2 is fine.

Next, set the computer's NIC properties to 10T, half-duplex. Use the firmware installation software, not the firmware upgrade option on the router's own configuration screeen.

Finally, do a loooong reset. Hold in the reset button until the diag light lites, then goes out. Now set all of your router parameters from the configuration screen.

Done.
 
I know the procedure for upgrading the firmware. I have installed a dozen linksys routers and everytime I disconnect all the pcs (physically) from the router and the wan connection also. What intrigued me this time was the fact the wireless router wouldn't work when I was daisy chained to another router. I haven't had time to do some more experiments, maybe one day...

Set the BEFSW to router and not the Default of Gateway mode.

 
Hello bcastner,

Will give your suggestion a try when I get a chance.

thanks
