Re: ThinkPad X250 Mobile internet question

2017-05-18, 13:59 PM

Solved. Sierra software v. 2.32.10970.4625 fixed the issue.
LTE/3G connections have been stable since. Tested various SIM and networks.

I have X250 20CL-S4XJ00. There is no WAN card installed BUT there are no cables for connecting a card. 

 

Meaning no WAN support available in this machine, or?

kennyabcd2011,

what's your laptop MTM code (starts with 20CM or 20CL)? It's needed to ensure laptop is wwan upgradable, i.e.has not only sim card holder and reader factory installed, but wwan antennas set. So, it's no needed to disassemble the laptop at this stage. If the laptop model is CTO, its serial number is needed. Do not share it here.


In your post you indicate that certain MTM codes and serial numbers are not upgradable with an WWAN card. I am trying to determine if my unit is upgradable. Can you please explain how I can determine whether my computer is upgradable or not by looking at these numbers? Thank you.

Fill in MTM in the search field and get its specification.

If the laptop' MTM isn't listed or it's a CTO model, take a look at its pats list (antennas type and WWAN adapter presence including) by s/n

Re: ThinkPad X250 Mobile internet question

2019-08-25, 14:57 PM

I've looked through this thread and don't see the solution.

 

I have an X250 with latest Windows 10 updates, Sierra EM7345 4G LTE and software 2.36.10970.4674, and a Three mobile data SIM which gives me 200MB/month free.

 

If I disable WiFi and click to connect mobile data it shows as connected but I'm unable to connect to anything on the Internet. It seems as though Windows is not correctly managing the IP reconfiguration when I switch to mobile data.

 

Here is the output from ipconfig /all and netstat -r while on WiFi (with IPv6 and irelevant adapters and virtual adapted edted out):

Notice that the ping to the mobile default gateway gives a General Failure (whatevr that is) and to a DNS server provided by the mobile data provider gives a destination unreachable from the IP address of the WiFi adapted, now disconnected, even though it's no longer in the routing table!

 

A clue would be greatly appreciated.

Once wifi is disconnected and MBN connected, try:
ipconfig
ipconfig /renew
ipconfig

The 1st and 3rd commands will show current connection' IPs

Thank you x220forme for the suggestion, but no improvement. Tracert shows it still trying to go through the WiFi DHCP address even though WiFi is disconnected and that address is no longer in the routing table!
