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?</span></div><div id="yui_3_16_0_1_1422814494030_16732" dir="ltr"><span><br></span></div><div id="yui_3_16_0_1_1422814494030_16732" dir="ltr"><span id="yui_3_16_0_1_1422814494030_18233">Thanks.</span></div> <div class="qtdSeparateBR"><br><br></div><div class="yahoo_quoted" style="display: block;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 12px;"> <div style="font-family: HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif; font-size: 16px;"> <div dir="ltr"> <font size="2" face="Arial"> On Sunday, February 1, 2015 1:43 PM, Olwe Bottorff <galanolwe@yahoo.com> wrote:<br> </font> </div> <blockquote style="border-left: 2px solid rgb(16, 16, 255); margin-left: 5px; margin-top: 5px; padding-left: 5px;"> <br><br> <div class="y_msg_container"><div id="yiv4966622635"><div><div style="color:#000;background-color:#fff;font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;"><div dir="ltr" id="yiv4966622635yui_3_16_0_1_1422814494030_5566"><span id="yiv4966622635yui_3_16_0_1_1422814494030_5728">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.</span></div> <div class="yiv4966622635qtdSeparateBR"><br clear="none"><br clear="none"></div><div class="yiv4966622635yqt5063552944" id="yiv4966622635yqt43468"><div class="yiv4966622635yahoo_quoted" style="display: block;"> <div style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:12px;"> <div style="font-family:HelveticaNeue, Helvetica Neue, Helvetica, Arial, Lucida Grande, sans-serif;font-size:16px;"> <div dir="ltr"> <font size="2" face="Arial"> On Sunday, February 1, 2015 11:32 AM, Ryan Coleman <ryan.coleman@cwis.biz> wrote:<br clear="none"> </font> </div> <blockquote style="border-left:2px solid rgb(16, 16, 255);margin-left:5px;margin-top:5px;padding-left:5px;"> <br clear="none"><br clear="none"> <div class="yiv4966622635y_msg_container"><div id="yiv4966622635"><div><div class="yiv4966622635"><blockquote class="yiv4966622635" type="cite"><div class="yiv4966622635"><div class="yiv4966622635" style="background-color:rgb(255, 255, 255);font-family:HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;"><div class="yiv4966622635" dir="ltr" id="yiv4966622635yui_3_16_0_1_1422805161160_5096"> My Thinkpad T61 (also Ubuntu 14.10) works fine with no weirdness. </div></div></div></blockquote></div>So it’s your laptop not Comcast.<div class="yiv4966622635"><br clear="none" class="yiv4966622635"></div><div class="yiv4966622635">It’s amazing who quickly people blame their ISP when only one device on the network has issues.</div><div class="yiv4966622635"><br clear="none" class="yiv4966622635"></div><div class="yiv4966622635">I suspect something is RFU with your firewall (UFW).</div><div class="yiv4966622635"><br clear="none" class="yiv4966622635"><div><blockquote class="yiv4966622635" type="cite"><div class="yiv4966622635yqt2734583681" id="yiv4966622635yqt01252"><div class="yiv4966622635">On Feb 1, 2015, at 9:47 AM, Olwe Bottorff <<a rel="nofollow" shape="rect" class="yiv4966622635" ymailto="mailto:galanolwe@yahoo.com" target="_blank" href="mailto:galanolwe@yahoo.com">galanolwe@yahoo.com</a>> wrote:</div><br clear="none" class="yiv4966622635Apple-interchange-newline"><div class="yiv4966622635"><div class="yiv4966622635"><div class="yiv4966622635" style="background-color:rgb(255, 255, 255);font-family:HelveticaNeue, 'Helvetica Neue', Helvetica, Arial, 'Lucida Grande', sans-serif;font-size:12px;"><div class="yiv4966622635" dir="ltr" id="yiv4966622635yui_3_16_0_1_1422805161160_5096">Still having problems with my Comcast Internet service.
