Intermittent VPN conection after modem replacement

[tgswoodsman]

I replaced a faulty Motorola SB5101 with a new SB5101. I use a Netgear router. Everything worked fine initially. After awhile our VPN connection stopped working, then started ...etc. Normal internet access works fine. Is the problem with the modem? the VPN? The computer? Comcast?

We use a IBM ThinPad laptop, XP Pro. This computer connects to the VPN successfully at all other wifi networks that we'v e used.

Well, you can connect directly to the modem with one computer to test if the modem or Comcast are causing the issue, that will start to narrow it down. Hard to imagine this is the modem if you have normal Internet access, that modem is pretty dumb and doesn't care what kind of traffic goes through.
