I was thinking the same thing, but the old Microsoft one wasn't supported by Verizon (or even Microsoft...) so I got the Linksys one so Verizon "support" could help me identify any problems. Their support turned out to be a transfer to the Linksys support line. They showed me how to completely reset the router the last time it went down. The little Local Area Connection icon on my computer often has the red "x" saying that a network cable is unplugged... But right now for example, that red x is there and the internet connection is still working (I'm on the wireless desktop) >>I've long suspected that the Verizon DSL is part of the problem, and >>in fact there were instances where it was completely down for a few >>hours and then just mysteriously came back...( I verified this by >>connecting the upstairs desktop PC directly to the modem). >>But lately, the DSL seems to be working fine. > >Have you carefully observed the lights on the DSL modem?

Unfortunately, I'm real big on the speculating, particularly when I haven't got a clue... I'll check the WAN settings, the dsl lights, and possibly just try to document what happens when I just reset the modem. But I'm going to deal with Azureus first. Thanks so much for your input. I'll post back tonight after I change those settings. --N |

For starters, let's just talk about the wired computer! The next time this problem happens, run IPCONFIG /ALL in a CMD window on the wired computer, and post the output here. See if you can access the web interface on the router from the wired computer. If you can't, post the *exact* error message. >The little Local Area Connection icon on my computer often has the red >"x" saying that a network cable is unplugged...

Greetings once again. Last night I thought I had the problem identified. Everything went down, but came back up with a reset of the modem(only) I wrote a very long description of all the details...I listed the cmd ipconfig /all results for both desktops, and most of the settings for the router. But then in the middle of all that, I lost the connection again. I ended up losing all that information before I sent it along to this group. This time, a reset of the modem didn't change anything. The modem and the rourer seemed to be working fine. I never lost connection with the hardwired desktop (which was always connected to the router). So this morning, all of a sudden the wireless is working again. This coincided with the lease line time. I have that set for "0" which apparently means one day. I'm getting paranoid that this is all going to crash again any minute now so I'll just send this along. I have documented all the settings you advised I look into. It would take all day to type them all in... I have all the router settings, all the ipconfig results etc. for both desktop pcs. Please let me know which specific information would be of use in diagnosing my problems. Thanks very much. --N |

Have you power cycled the router (linksys) and the Westel together? What I mean here is pull the power plug on both and wait about 30 seconds. Now power up the linksys router, wait a few seconds (to allow it to get a head start) and power up the westel. What we are doing is, ensuring the westel is 'mated' to the MAC address of the linksys router. Next is the Linksys router the only DHCP server on the network, this function is disabled in the WAP downstairs, correct? Next run through the answers John Navas has asked for. fundamentalism, fundamentally wrong. |

Greetings,
Sorry it has taken so long for me to respond. My setup has been going down so frequently, and the situation keeps changing so much, it’s difficult to even try to explain the symptoms. But I’m pretty sure I have the source of the problems narrowed down to the router. I bought the thing thinking that all routers in this price range are essentially the same, but I’ve come to find out that this router has well documented problems with P2P programs. So long story short, I just won’t use any of them for the time being, and I’m shopping around for a new router. Thanks for all your help. I’m going to start a new thread with questions about what exactly I should be looking for in a router given my setup and plans. I’d appreciate any advice any of you might be able to offer. Thanks again. --N |
