Edimax router not connecting to the modem

PhantomTa2 · 07-10-2009, 22:33

I bought one of these routers a few months back and had problems with it as it kept dropping connection to the modem. So I exchanged it for another of the same model assuming the first was faulty and the second one is doing it, now, too.
Behind the router is fine, all systems can talk to each other and I can ping the router but not, for example, the DNS that my ISP uses. I've tried deleting and recloning the MAC address, which is what Edimax told me to try, (the first time I tried this about a month ago it worked).
Under the internet status it just says "Attain IP Protocol : Dynamic IP disconnect"
Plugging my PC directly into the modem is fine, everything works as it should do. But, after soft-resetting and hard-resetting the router, the problem still persists. The most recent was today, my wife was on her laptop on the internet playing one of her games, then she rebooted her laptop (not touching the modem or the router) and it wouldn't connect to her game or google. I pinged the router and it was good, pinged the DNS server and says "destination net unreachable"
If any one could help with this, I'd be very grateful. I've googled for quite some time but haven't come across an answer as to why it might be doing it or how to sort it out.

*EDIT* I should add that when I log into the router and go to the internet status it just says "Dynamic IP Disconnect" and once the router is between me and the modem, I can't log into the modem admin page, either

Try giving all the machines on your network a static IP then switch off DHCP in the router.

Already done that. That's how I like to set up my LANs straight away, as some machines need ports forwarding, but it worked one minute and now not at all. I've even reset back to factory defaults and it won't connect to the modem then, either

I found a fix for it today, but I'm confused as to how and why it worked. I only noticed it because I'd been working on it for hours.
I tried it with the RJ45 cable directly into the router, wouldn't work. I disabled that and tried the wireless card, that didn't work. I reset to factory default and went into the router using the cable, could get into the router, but not to the modem, so I changed again, only I left the cable plugged in to my system and the router. It worked. Figuring I'd sorted it, I unplugged the cable from the system and the router, didn't work. Tried it plugged in, but disabled, it worked. I couldn't believe what I was seeing here, especially as the RJ45 socket was disabled, so I tried it 5 times more, and it seems to have fixed the problem.
Can't understand why or how, but it works with it plugged in, even when disabled. *shrugs*

So long as it works.

It's done it again. Won't connect to the modem at all.

Behind the router everything is fine. All systems can connect to each other and communicate, but the router keeps dropping the connection to the modem. I've even reset the router to factory defaults and that won't work, either. I've tried with TTL enabled and disabled but neither work. I've done the "Quick Setup" with the same result. I just can't connect to the modem with my router. At the moment I'm connected by my PC into the modem, which is annoying the hell out of my wife right now as she can't do her internet things that she needs to do. I've tried with the MAC address as all 0s and as a cloned MAC address. I think I've honestly tried everything I can think of and nothing is working.

Here are the screenshots showing how it is set up

*EDIT* Now it's working again, but I'd still like to know why it was doing it and why it works again now

here's an idea - unplug the coax from your modem - it'll work like a dhcp server and dish out IP's in the 192.168.100 range. see if your router is able to maintain it's lease and refresh IP's etc.

if this is fine, their may be some issue with getting IP leases from the Virgin DHCP - although this isn't very likely.

if the problem continues, I'd say their is a bug in the firmware for your router - I had a similar issue with a cheapy wireless router and found that I had to factory reset it if I tried to use some of the settings on it (QOS and stuff) firmware update fixed it =)
