Some months ago after a power failure-our access to the internet from the network *ended. In the course of troubleshooting, I thought I had isolated the problem to the router. A single computer connected directly to the modem connected to the internet just fine-so it must be the router, right? So we bought a new one-same problem. Linksys tech support set us a new one-didn't help. They were boggled, I was boggled.
A friend mentioned that I should try replacing the modem-which didn't make sense to me-so I did it anyway. Bingo-problem solved. This led me to believe that the modem was the problem-something in the power failure or surge had damaged the modem in such a way that it no longer functioned connecting to our network-but worked fine connected directly to a single computer.
This opinion was reinforced when some months later, we had another power failure. Same problem. This time, I exchanged the router straight away-with the expected positive result. The problem was solved-it was the modem.
Until yesterday. Another power failure (small community in Alaska). So, I felt supremely confident that the problem could be fixed by replacing the modem-as it had two times past. But-this time the new modem doesn't fix the issue. And neither does the second modem I try. 15 power cycles of both modems and router later-I'm baffled. Anyone familiar? Help? Please?
An interesting wrinkle-when I power cycle the router, the network will connect for about 10 seconds to the internet before it loses the connection. I've got a new router on order as well-just in case. grumble.....
I have one machine using a static ip (to interact with some web aps) the rest are assigned using dhcp.
Although this is almost certainly not the cause of your problem, if you are using DHCP, then I'd recommend using DHCP on ALL machines.
You can use DHCP to assign a static address to any machines that need a static address. You will need to know the MAC address of the machine's interface. You can then set-up DHCP to always assign the same IP address to that MAC address.
By having all of your address configuration in one place, it eliminates a lot of potential for misconfiguration.
As to your problem - you should be able to diagnose the problem using ping and traceroute. Can you ping the router? The modem? The gateway address at your ISP?
What i've done is have the static ip -100, and the dynamically assigned ip #'s to begin +100. Linksys tech support said this should work fine-but I do think I'll use your method instead as it's a bit more elegant.
Yes, I can ping the router-the connection problem seems to be intermittent. My new router should arrive next week and I'll see if it fixes things.
All ideas welcome...
setup issues are usually consistent, it either works or doesn't
I am guessing you don't use a UPS, well a power surge before or during your power failure would easily fry the delicate bits of your router, or modem
Strange tho, cos most routers are protected by their DC power pack, sounds mad, mmmm,
but if the power packs are no longer delivering the right power, then the router an modem would be os
Get youself a UPS
You might
a simple, fuse protected strip might not cut out before the power got thru to the power packs.
Anyways,
power cut
+
incessant replacing of routers an modem
= what
Afterall, if this only happens at power cuts, and the equipment is 100% protected from power surges, I am baffled
it would be interestin to hear the solution to this
