Surface 3 LTE has no internet on HSPA+ network

Hello Plantje, Barb,

Haven't completely solved it, but alleviated the pain :-)

I've been real frustrated again about the issue, as it makes me interrupt my navigation software, while I'm using it. Maybe understandable I'd like to be busy navigating, not troubleshooting while on the go, so I searched my **** off and tried different things and joint another forum (KPN, the provider). The forum members were real understanding, but out of nowhere I found something helpfull. Which is great, because this was the worst issue of an otherwise very comfortable tablet to me.

 1st) Tried adding authentication protocol for APN fastinternet since my SIM is busines: PAP instead of none. (This was a hint from KPN). Didn't work, allthough it might help for general smoothness if you're on a busines-subscribtion, so added here: Go to W10-settings/Network/Mobile/Advances settings for APN:

APN: fastinternet

Username: (leave empty)

Password: (leave empty)

Proxy: (leave empty)

Port: (leave empty)

MCC: 204 (don't have this option)

MNC: 08 (don't have this option)

Authentication type: PAP

APN type: internet (left default)

2nd) Added simpin, since after protocol-change the device claims the sim being blocked and I need a simpincode2. (simply added 0000). Didn't work, but have to say this was a simpincode1, may make a difference in the future if I find simpincode2. For now took if off again, as during protocol change it locks the sim (untill you provide the pin).

3RD) THIS IS IT: THE STEP FORWARD: DISABLE SELECTIVE SUSPEND FOR THE MOBILE ADAPTER:

Go to Configuration/Network/Adapters/Mobile/Properties/Client for Microsoft-networks/Configure/Advanced/Selective Suspend

SWITCH TO: Disabled

Reboot machine

After doing this, I noticed that not everything crashed immediately anymore when getting an involuntary protocol-change. The browser doesn't get stuck and is rebootable and the adapter does switch off. After some (uninterferred) waiting the internet even came back!!! JEEEEEJ. Unfortunately I cannot yet get thetering from my phone to give internet (does connect) and haven't found a way to definitely reset the mobile adapter, but I don't have to reboot anymore. I will be further investigating in how to do this and will stay open for suggestions. Hope this also helps you Plantje.

Hi Aart,

The first two steps I cannot perform. But the third step is really promising! I am currently testing it. One thing that I did notice is that if I am connected to HSPA+ I have a solid (but slower than 4G) connection and it stays connected to HSPA+ (and working) even if there is 4G available. So, that actually looks good! I can disconnect the adapter, have it find 4G and connect to it. And then the same happens for 4G. No matter how thin the signal is... if it is there it is connected.

These are my findings so far. I'll keep you updated!

Thanks for figuring this out!

Vriendelijke groeten,

Not sure if selective suspend will fix the issue:

Hi Plantje,

Of course selective suspend is not the culprit, nor is the solution a fix, merely a work-around, disabeling other functionalty (in this case selective suspend). Something of which you seem to need rather a lot these days with a microsoft machine. Ever tried getting all lockscreens (3: at boot, at wake and at display back from off) and all loginscreens (again 3, same as lockscreen) to be gone forever? A new machine with a lot less issues is also what I am waiting for. Still I'm happy for this workaround for now and happy you are too :-) 

You can refresh the adapter? Awesome, automating a refresh the moment the adpater goes to HSPA+ for me is too complex. But I am writing a script to refresh it faster. 

Will let you know if it finishes, at the moment I'm trying to figure out which services are connected to broadband. Furthermore: definitely new machine.

Groet, Aart

By the way: knap gevonden die andere threat! Jammer genoeg geen oplossingen.
