This issue may have been addressed but I missed it. I removed the battery and restarted several times but when I am on my pc with no other user its works ok, but if my wife uses her pc it comes to a complete stop. Any suggestions would be helpful. Also please note that several times a day If I read a article and rather take me to the follow up, I am taken to the 6602 Admin. page instead. and now my wife's pc is doing the same thing, and her pc has never been to the Admin. web site. I have removed the battery, sim card and reset the unit with no luck.
You can read about the most current firmware here to verify you’re using it.
Try this, login to the admin page, Jetpack Settings > Advanced > Networks. First, disable Connect Delivery if it is enabled, save settings, and restart the Jetpack. It may restart after using save settings & confirm. If it doesn’t restart then logout, power down the Jetpack, wait a minute, power up and test to see if that change fixed it.
If not, login, go back to Networks, change Preferred technology from Global to LTE Only, save changes, confirm, and it should restart. Test to see if that change fixed it. If 4G LTE doesn’t work, try CDMA Only (3G) and retest.
Next, on the Advanced page, click LAN, disable IPv6, save changes, restart and retest.
If none of this helps and the Jetpack is still under 1 year warranty, you might have to throw in the towel, call Customer Service (800) 922-0204 to see about getting a warranty replacement.
