Q: I have cable modem surfboard4200 and recently I have not been able to surf the web or anything related internet since my internet is still running off.
My modem lights are all on and the only way I can back on the release / renew my NIC IP address even if the same IP number and DNS servers get. Thats the only way to work for another half a minute before again.
When goes out, I cannot even ping my ISP or the router, but if I refresh the NIC is working again. My NIC is the same address every time, so nothing changes. Whats going on?
Windows XP Pro sp1
SMC 10/100 NIC
Surfboard
Also 4200 cable modem, when I do a tracert to my ISP, it lists three 30ms 30ms 35ms pings 127.0.0.1 things
localhost u003c —— this is normal for this so high? What u003e localhost is anyways?
then star Stream 9ms 8ms 8ms 7ms 8ms
then other star Stream 9ms
Best Answer: Try your antivirus, I had a virus called "Denzuk" 2 years ago, it did the same thing.

Re:Hmm thanks for the tips guys. I checked my signals and they all are within spec. Download SNR 36db, download power 0dbmV, upload 23db. I hooked the modem up to another computer and it works fine, so this means something is wrong with my computer. I ended up calling my ISP and they will just come and fix it on monday.
The only thing that changed was that I got the new .42 version of Overnet. But this is happening even with no overnet running. I tried running the modem through a switch and then to my computer. As soon as it connected to my computer no internet. Wierd.
Re:Call your ISP and tell them you've got intermittent connectivity, they'll fix the problem.
Re:Maybe Signal strength, get the cable guy to come over and check signal strength on different points of your line.
Re:I have the same problem with my surfboard modem from time to time, but not as often as you. My network "connection" would always crash every other time I left a game room at zone.com. It would also crash periodically when my dad used Kazaa. Like yours, all the lights are on and I still have an IP address. I just can't get anywhere!
At first I thought that somehow certain applications were messing with the system's networking software, but if that were true, the network connection should only be failing on one computer, so it seems that the source is either the modem or the switch.
Perhaps the modem's analog to digital converter is failing, so it still is getting a signal from your ISP, but it's not sending a signal to your computer??
Re:localhost is your computer … 127.0.0.1 is by definition "Your Computer"
This makes me think that you've got a proxy problem going. It's looking back to your computer for "permission", then going on to starstream.
I'm assuming system used to work. If it used to work, what has recently changed – either hardware (new surfboard, new router, …) or software (proxy, os, …)??? It's a different set of troubleshooting questions if it's never worked … try a different computer on the surfboard, try your computer on a different surfboard, …
Good luck
