Well this is weird.

One of my computers has zero internet connectivity. That means all browsers and file-sharing programs are kaput. I cannot go on the internet on that computer nor use any torrenting\sharing programs.

The firewall recognizes these programs and allows it through, but recognizes zero traffic. However, it still registers the "incoming threats" counter, which is rising up as a somewhat alarming rate. The "ping" command works, as i recieve the ping back. The router is fine, since the other two rigs on it still are connected.

So i either have a bad cord, a bad card, or my IP is no longer valid.

Any suggestions?

Your ISP may be the problem, so ask them what's going on if you can.

I have 2 computers, and if I switch to one from the other, I have to call Comcast and have them reset it.  Before that, the lights come on, and it is "connected" but nothing will transfer without their say-so.

Switch suspected bad for known good and isolate the subsystem. IE switch the cable then the card. Usually it's the cable.

That's fucking weird. What OSes?

Win2k, on both but the same drive too.  I moved the HD from the old computer to my new one and had to call Comcast support to fix the connection. The modem's lights turn off and then on, and then it works. Later on I put in a SATA drive, removed the other drive, did a clean install, and didn't have to call them to use it.

When the new one's gfx card broke I switched back to the old computer (with the older boot drive installed).  I had to call Comcast support again.

When I switched back to the new computer, I called and said "I've switched computers and I need you to do that thing where you re-activate it to recognize the new computer."  He knew what I was talking about, and he did it.

So I deduce that Comcast controls not only how many computers you use, but which one. My laptop from work won't connect either. So if I have a friend who comes to my home with a laptop and wants to connect, he can't, yet I pay for internet service. So shitty.

Well, after six reboots, swapping cables, restarting the router, and a system restore to two days ago, it works.

Thanks!

When anything about my computer doesn't work, I try thinking logically first, then I swear, then the music from 2001: a space oddysey plays, I start jumping and screaming, finally grabbing a bone and beating it to pieces on the ground. If it doesn't work by then, I bring it to the computer store.

That's pretty I'm a edgy teen. Have you complained to comcast?

Oh, I bet you could fix that by having your main computer connected directly to the modem and feeding internet to the rest of your network.

Now i found the culprit. The newest Windows update seems to have triggered something on the computer that rendered it unable to connect to the internet.

I only found this out after ALL of the computers on the router have been losing connectivity. So i tried the system restore to before the update on this one and it somehow got connection back.

What the devil is going on?

Welp, looks like the newest Windows update killed internect connectivity with Zonealarm Clients. Guess what's installed in all of the locked-out computers?

[FluxCapacitorClock]

I've actually heard about that!

Goddamn, I hope it doesn't happen to me.

Does anyone by chance have an alternate firewall program that i can use until this blows over? Just going online with windows firewall makes me feel like walking into a prison shower naked with a big bulls-eye painted over my ass.
