Linksys EZXS16W Switch + BEFSR11 Cable/DSL Router Problems

If I am posting in the wrong group, please let me know.I have a Linksys BEFSR11 Cable/DSL Router. Up until yesterday, I wasusing a Linksys EFAH08W 8-port hub to share this connection to severalcomputers. That worked fine.I am planning to add more PCs to my network, so I needed somethingbigger than the 8-port hub. I decided to go with the Linksys EZXS16W16-port switch. That gave me plenty of ports and the added benefits ofa switch (instead of a hub).Unfortunately, now I am having problems.With the switch, I lose the connection to the router (and thus the WAN)frequently -- say every 20-30 min. When this happens, I can't evenbring up the web admin interface for the router from inside the LAN.Restarting the switch does not seem to help. Oddly enough, restartingthe router is all that seems to fix it.After stuggling with this issue all morning, I took out the switch andput my hub back in. Now it seems fine again.Some other details that might help:On the router, I was a little confused about whether to use the "X" or"||" (crossover or straight-thru) setting for the uplink port. Themanual seems to indicate the straight-thru setting for a switch with across-over uplink port (which the switch has, I think). But it seemedto behave exactly the same no matter how I set this on the router. Iam using a straight-thru cable.Also, I have the MDI/MDIX setting on the switch depressed, which shouldbe the correct setting. According to the docs, "To utilize the port'suplink capability, the MDI/MDIX button must be depressed. If thebutton is not depressed, port 16 will function as a normal 10/100 port."

Ugh. I lost LAN access to the router again. When it happened, the LAN PCs could see each other, but not the router (and, thus, not the WAN).

Once again restarting the router fixed it.

It was up for about 4 days, I think.

Pulling the thread back in alignment! lol

After reading your last post now I'm beginning to wonder whether you are having some router issues. Maybe it seem to start at the time you added the EZ16 switch but could have been a coincidence just as well. Two things I would try.

Bypass the router for a few days and hook a system directly up to the modem and see how long it retains it's WAN connection.

I think I'd try a different router just for grins. You may or may not wish to spend money for a new one BUT it might be as simple as replacing the router.

Another thing you might want to take a look at is your modem connection signal levels. Are they within spec? Perhaps your line has developed some signal issues which is causing the modem to not have as good a connection as it should have thus causing the router to do what is is doing. Maybe even a modem change might solve the problem. Do you own or rent your modem?
