[Merged] DNS (ARP) dropping frequently issue on 20M service

[j-a]

I've just found out that the router can use a ping test to determine the viability of WAN1 instead of ARP, so I'm going to try it using that. Downside is that pings always seem to work throughout the dropouts so it may not be an adequate test to cause the switchover to WAN2.
FYI the network connected to the router has a Vista 2 Core laptop (suffers LESS) down to an old PC running W2000 (suffers MORE) - I put this down to the Vista TCP IPv4 stack being more robust. If only I knew what was better in the rewritten stack it might help screw this bug down tighter.

Aha!

My machine (suffers often):
Windows 2000
Dual Athlon MP 2600+ (Barton)
2GB CL2 SDRAM
Quad SCSI U320 15Krpm disks, striped and mirrored on a hardware RAID controller
Hardware 100Mbps LAN connection

Other machine (rarely suffers):
Windows 98SE
VIA C3 600MHz
512MB DRAM
Single 5400rpm IDE disk
Wireless 54Mbps (sometimes) LAN connection

Once again this crap is happening, every single day for over a week I'll be unable to resolve any URL's and all websites time out. This isn't a problem on my end it's affecting my brother also who lives miles away. Virginmedia need to get this sorted.

[edit]

example of a tracert when this is happening

I am having exactly the same problems, getting very frustrating

configuring your connection to use OpenDNS is really not the way forward. check the latency and stuff out

if you want, you can PM me and I can give you a couple of IP's for some DNS servers in the UK which're pretty good.
