I have been having issues with My Wr44 V1 connecting to AT&T tower, tried upgrading firmware from 5180 to 5235 Lost all connectivity. Installed 5284 for the V1 and am getting the following. I don’t have many options for configuration, here is what the event log is showing. I cut a few hours out of the middle. AT&T is suggesting firmware issues. Anyone else see this? 15:15:14, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:15:04, 08 Dec 2015,Network technology changed to WCDMA 15:14:53, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:14:03, 08 Dec 2015,Network technology changed to WCDMA 15:13:53, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:13:03, 08 Dec 2015,Network technology changed to WCDMA 15:12:53, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:12:42, 08 Dec 2015,Network technology changed to WCDMA 15:12:22, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:12:02, 08 Dec 2015,Network technology changed to WCDMA 15:11:31, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:11:02, 08 Dec 2015,Network technology changed to WCDMA 15:10:51, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:10:11, 08 Dec 2015,Network technology changed to WCDMA 15:09:30, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 14:17:49, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 14:17:29, 08 Dec 2015,Network technology changed to WCDMA 12:25:12, 08 Dec 2015,WEB Login OK by administrator lvl 0 11:26:29, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 11:26:22, 08 Dec 2015,PPP 1 up ---

Basicdave, In the log I see that the PPP 1 interface came up which says that the unit connected to the carrier via a PPP session See log entry below 11:26:29, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 11:26:22, 08 Dec 2015,PPP 1 up You should see the mobile IP address under the Management–\>Network Status–\>Interfaces–\>Mobile–\>Mobile Statistic page. This will show you the Mobile IP address that the carrier has given the unit. ---

Thanks Rasman, It does connect, but sporadically and at times I will lose it all together. It is 4 1/2 hours away so I have it set-up on a switch now that reboots at 10 minute intervals when the public IP is not pingable. This seems to have worked as far as getting it reconnected and not falling into a loop that leaves me completely blind. However I have not seen this recurring change of technology on any of my other sites. 15:12:22, 08 Dec 2015,Network technology changed to HSDPA/HSUPA 15:12:02, 08 Dec 2015,Network technology changed to WCDMA When connected to UMTS I am at -72 so I wouldn’t think signal is an issue. I just checked the event log and it is continuing to bounce between - WCDMA and HSDPA. I am not even sure if this is necessarily a problem, I have just never seen it before. ---

These are different 3G technologies, and I believe WCDMA is the older/slower one. I’m not really sure why it’s changing so often. Do you have a mobile IP address? ---

Thank you jeremym, When Connected I do, I use all fixed public addresses. I have also just started experiencing a connection issue with Verizon same nomenclature WR44v1 router same firmware upgrade. This one is on the other side of the state though. ---

Have you tried SureLink? [http://knowledge.digi.com/articles/Knowledge\_Base\_Article/Surelink-Configuration](http://knowledge.digi.com/articles/Knowledge_Base_Article/Surelink-Configuration) There should be a Wizard in the WR44v1 web UI to set it up.
