Internet prollums - The online computery journal thingy of a turtle

So, a day after I came home from Chicago, my connection to the internet suddenly went poof. The next day I called tech support, and we tried various things. Long story short, there seems to be a problem with the router. Right now I'm on Mom's computer, which is connected directly to the modem. I tried connecting my computer to the modem but it didn't work, which I'm guessing is because one is a crossover cable and the other isn't, or something like that.

Anyway, I'm stuck using Mom's computer to surf the web instead of my own until the guy from Data Doctors can come to look at the router, which isn't till Monday. There won't be any new cartoons from me until after that time.

Honestly, most Ethernet cards are polarity-sensing; that is, they'll work with a cross-over cable or a straight-through cable. However, some Cable and DSL Internet providers still lock in what Ethernet card is able to use the Internet connection. My ISP actually does that for security reasons, but with Ace, I just go onto the web site with the legitimate computer and "unlock" the IP address. (It automatically re-locks at midnight.) Or I call the ISP and ask them to do it if I'm in a bind.

(Let me add, though, I don't know how your particular provider does it. It varies from provider to provider and even market to market.)

It's Comcast; they do what most of the cable providers do, which is lock access based on the MAC (from the RF side) of the cable modem. Some cable modems learn the end station MAC from the ethernet side and have large ARP timeouts (or possibly NEVER time it out?), so the cable modem has to be restarted if the end station changes.

Also, KT's region used to be Road Runner (TWC), who controls access by cable modem MAC.

(For KT's benefit, "end station" refers to the device that's directly connected to the ethernet port of the cable modem.)

Most (if not all) Gig-E cards can auto-sense, but most 10/100Mbps cards cannot. Cable modems probably don't have the new 1000Mbps PHY yet.

And I think I have about as much chance of understanding any of that well enough to do anything about it myself before the Data Doctors guy shows up on Monday and does it for me as I do of learning the complete rules and history of bridge in the next three seconds, which is why I'm glad the Data Doctors guy is coming over but Monday at 2:00 can't come soon ENOUGH.

If it's Comcast, I have their modem too, different router.

Two things to try on the modem itself. Unplug, wait a minute, and replug, and if that doesn't work, use a pen to click the recessed Reset button in the back.

Then try the same thing on the router, it will have a reset button as well.

If neither of those work, time to call in the pros.

Hope they get it sorted. I eventually gave up on Comcast because they just weren't reliable. My connection kept going down on weekends or after hours, and of course at Comcast there's no one around who knows how to troubleshoot anything on a weekend. During business hours, when it was working, there was nothing to troubleshoot. I couldn't get past the people who only knew how to read scripts, so after they asked me to replace the modem for a second time I gave up and got DSL from Speakeasy instead. Speakeasy actually has tech support people who know how to troubleshoot problems, and they work weekends.

Is Speakeasy available in Houston?

I don't know, but you can check at www.speakeasy.net.

I should mention that, being DSL, it's going to be slower than cable Internet, so you may want to stick with Comcast if you're getting OK service. I've been repeatedly impressed with Speakeasy's tech support, though. Also, they do "dry line" DSL so you don't have to get conventional phone service if you don't want to.

If they're in your area and you decide you're interested, PM me and I'll send you a referral good for a $25 credit.
