Hi. I have a Pantech UML290 USB on windows 7 64 bit. I just updated to the newest version of VZAM v18.104.22.168.2672s firmware L0290VWB522F.242 and no longer get a 4G connection. I uninstalled this version of VZAM and installed an older version I had archived (v22.214.171.124.2642k) and now I am back to my 4G connection. I cannot remember what version I had just previously to v126.96.36.199.2672s, so can you kindly tell me where I can get older versions of VZAM. It seems that at least for me v188.8.131.52.2672s is not working.
Bump. Another note: my neighbor had the same problem with VZAM v184.108.40.206(2677s) firmware L0290VWB522F.242 and had to uninstall it and revert back to v220.127.116.11.2642k. I had the problem on two different machines as well. Seems VZAM v18.104.22.168(2677s) firmware L0290VWB522F.242 is DOA for us anyways.
I know a stable connection is very important. On the VZW site we do not have the older versions of VZAM available. I haven't seen this issue with this version. Have you tried re-downloading the newest version v7.6.4 (2672s) to attempt a successful connection? If you are still experiencing issues please let me know so I may further assist you.
