Every 30s-2mins or so, my router loses connection to the internet, then reconnects a minute later. It's intensely frustrating, obviously, and has so far resisted all my attempts to fix it.
When I refresh the router status page during these losses I see these changes:
INTERNET SETTINGS:
WAN IP NULL
SUBNET MASK NULL
DEFAULT GATEWAY NULL
DNS ADDRESS NULL
ADSL:
TYPE FAIL [or Full Initialisation, whatever that means]
STATUS FAIL
so far I've tried resetting it, resetting my wireless NIC, uninstalling my wireless NIC, restoring the router to factory defaults, changing the channel, changing the channel to auto, placing the PC in the DMZ, and much more that I forget in a haze of troubleshooting.
halp?
(the router is a Belkin RangeMax, and my NIC is part of the motherboard, an ASUS p5 wireless deluxe)

It DC'd during posting. Luckily I copy pasted it before hitting new thread.

if you are losing your net connection entirely, it's probably as question for your ISP
that's why we call it the struggle, you're supposed to sweat
I got an ASUS RT-16N wireless router and without changing anything else, my internet experience is way,way better.
Psuedo-edit: I re-read what is happening to you and it seems like your computer can still connect to the router while it is disconnected. I agree with Eat it... I think you need to call up your ISP.
MTU is Maximum Transmittable Unit, the maximum byte size of outbound packets. Your router breaks up outbound data that exceeds this value into smaller packets for transmission. Most routers have a default MTU setting of 1500, which for some reason seems to cause a few ADSL providers systems to shit themselves when they encounter such a packet. Scaling the MTU back to 1432 often stabilizes the connection.
I'm curious as to why you would recommend 1432, since I haven't heard of that being a magic number before... I mean, that value would definitely work, but I would think it would likely solve the issue by just scaling it back to 1492 (the max MTU for PPPoE connections, which require an extra 8 bytes of overhead, and which I would assume is the "for some reason" that connections flip out in your post). In googling, I do see that for a couple providers in the past in the States wanted that value, but I think for 90% of connections your MTU should be either 1492 (PPPoE with its 8 bytes of overhead) or 1500 (other connection types) under normal circumstances. I use DSLReports as a resource for a lot of things, and here is their page on the subject. As you can see, they recommend 1492 or 1500, but give you a method to find a good MTU value if those turn out to be too high. They start out having you ping using 1472 bytes + 28 = 1500, and then your final MTU is whatever ping value worked without fragmentation + 28. I grant that this could be outdated if something has changed! I'm just curious since I hadn't heard of that value before.
