I've recently obtained an HP ProBook 640 G2 Notebook after my past employer gave it to me. I've since upgraded the RAM to 16 GB and installed the subject line WWAN module to give it cellular connectivity.
The problem is that it appears there's only one possible configuration option with the latest drivers correctly installed for this device and that's to either enable of disable selective suspend. The problem is that the cellular network I want to connect through directly using the SIM in the notebook has lousy a 4G signal but acceptable 3G one. Nevertheless, this WWAN will almost always try to get and hang onto a poor 4G signal (even with hardly any throughput) whereas re-negotiating to a 3G connection would make it usable.
I'm having to use the notebook via a WiFi connection tethered to my Android tablet. I've configured that to limit it to a 3G connection max but I'm surprised the Windows configuration options don't seem to give this same choice.
Additionally, on the very rare occasion when the WWAN module does downshift and get a 3G (HSDPA+) connection instead of showing LTE, although that connection will work and have throughput, its displayed incorrectly as 'not connected' whenever its anything other than a 4G connection. When I put a different networks SIM in the slot on the Notebook, it mentioned its updating its firmware but it didn't complete that process because it was only using that cellular connection at the time - its a bit like sitting on a tree branch and sawing through on the wrong side! Ive since retried with the laptop having a wireless connection when trying this but its made no difference.
Any idea how I can get this WWAN module to behave itself and work properly please (other than always having an acceptable 4G signal strength/reception)?
