Which model modem did they bring? > On Feb 1, 2015, at 1:44 PM, Olwe Bottorff <galanolwe at yahoo.com> wrote: > > Looking at the modem admin page, I saw that the errant T410 was only listed as its MAC address. Also, it was not listed as DHCP but always listed with a "Reserved IP" of 172.16.0.145 --which will not allow itself to be changed, even when I repeatedly try to choose DHCP and save. On a hunch, I changed (Ubuntu/Gnome) in the "IPv4 Settings" tab from "Automatic (DHCP) to "Automatic (DHCP) addresses only". Now it works . . . after a whole weekend of hair-tearing-out! Can anyone tell me why it wants to default to (won't change from) "Reserve IP"? And what did my changing to ". . . addresses only" do exactly? > > Thanks. > > > On Sunday, February 1, 2015 1:43 PM, Olwe Bottorff <galanolwe at yahoo.com> wrote: > > > I want to blame Comcast because these problems on the T410 don't appear when I use it on any other Wifi connection (I'll test again to make sure) -- and they don't even happen when Comcast gave us a loaner modem a few weeks ago! The new box is a dual 2.4/5.0 GHZ, while the loaner box was just 2.4 GHZ. On the new (and previous) 2.4/5.0 box I can't get any Internet logging into the 2.4, and the 5.0 connection gives me the aforesaid weirdness. There has been sporadic weirdness with other things too: Android devices tend to act up occasionally; an older Kindle has trouble getting online. I also tested this with the T410 on a straight ethernet connection to the modem -- same problems. To make it even more confusing, I tried Win8.1 on the T410 -- and it worked just fine. So if my T410/U14.10 works elsewhere AND with a different Comcast modem, gosh, it must be some very weird clash with the 2.4/5.0 Comcast modem and my T410/U14.10. Also, my Thinkpad X201 used to have weirdness, but it settled down and seems to work now. That's another wrinkle to this, problems come and go. For a long time we'd get Internet AFTER we waited 10 minutes or so after Wifi login, sometimes even with ethernet. But again, like I say, my older T61/U14.10 works fine. The only explanation I can think of is that the Comcast 2.4/5.0 modem and U14.10's network software don't like each other when U14.10 is installed on my T410. Just for laughs, I should get a non-Debian Linux version or even BSD for my T410 and see what happens. > > > On Sunday, February 1, 2015 11:32 AM, Ryan Coleman <ryan.coleman at cwis.biz> wrote: > > >> My Thinkpad T61 (also Ubuntu 14.10) works fine with no weirdness. > So it’s your laptop not Comcast. > > It’s amazing who quickly people blame their ISP when only one device on the network has issues. > > I suspect something is RFU with your firewall (UFW). > >> On Feb 1, 2015, at 9:47 AM, Olwe Bottorff <galanolwe at yahoo.com <mailto:galanolwe at yahoo.com>> wrote: >> >> Still having problems with my Comcast Internet service. Now it looks like my U14.10 Thinkpad 410 connection (wire or w-less) won't do ssh (no route to host), won't give me most web pages, but, amazingly, will connect with gmail, YouTube, and Wikipedia. Also, I can do software updates and synaptic. My Thinkpad T61 (also Ubuntu 14.10) works fine with no weirdness. >> >> LB >> Grand Marais (in spirit) >> _______________________________________________ >> TCLUG Mailing List - Minneapolis/St. Paul, Minnesota >> tclug-list at mn-linux.org <mailto:tclug-list at mn-linux.org> >> http://mailman.mn-linux.org/mailman/listinfo/tclug-list > > > > > -------------- next part -------------- An HTML attachment was scrubbed...
