I have purchased an EMG3525-T50B from the local computer store, however the router seem to be causing issues:
1. 5G Wifi not always working and need several restarts before coming up.
2. DNS intermittently stop resolving for 30 - 90 seconds.
3. External USB drive share sometimes stop working and require several modem restarts and power off's before coming back.

I have searched the internet and can not find any firmware updates, according to this forum i should get a firmware from the service provider that supplied the modem, in this case it is a computer store and they already suggested that i look at the manufacturer support site for firmware downloads.

Please advise on where i can download the most recent firmware, current firmware seem to be the initial release version.
