Yoga Book Very bad LTE speed

I am facing very bad speed using the LTE moden on my Yoga Book. I have been comparing the same SIM card between the Yoga Book, the Thinkapd 8 tabled and a mobile LTE-router. The speed I measured on the thinkpad 8 and the mobile LTE-router is about 60Mbps down and 30 Mbps up, on the Yoga Book I only get 7 Mbps down and 20 Mbps up. As I said the test is doen having all the three equipment the same place side to side. Also the Yoga Book measures the same high speed 60/30 if I connect via Wi-Fi to the obile router (so it is not the machine or windows being slow) it is obviously an issue with the LTE modem.

 

So my question is: Did anybody else experience the same issues, and did you find a solution?

 

Additionally I also obeserved that having the TP8 and the Yoga book at the same spot - about 10 meters away from the wi-fi router straight air no walls, no microowens - using a 5G wi-fi connection the TP8 shows 4 out of 5 bars while the Yoga Book shows 1 out of 5! This makes me wonder if the Yoga Book has in general an antenna issue - maybe due to the metallic body - or is just mine who needs ot be sent back to Lenovo?

Any sharing if your experience with those issues would be greatly appreciated.

Thanks

Re: Yoga Book Very bad LTE speed

Hi, what drivers is it using, and what is the device listed as in device manager (under network adapters)?

 

What provides the drivers, Microsoft? I don't see any on the Lenovo site.

Re: Yoga Book Very bad LTE speed

The device is listed as "CDC MBIM". The driver version is 10.0.15063.608 released by Microsoft (I guess it is the generic driver included in WIndows 10).

 

I did test it also very close to a tower so I had 5 bars of signal strenght. Here I got 20/2Mbps that is a little better, but in the same spot the TP8 (with same SIM) measured 80/10. SO that seem to confirm that the Yoga Book has both an antenna issue and that even with strong signal it perfoms very bad compared to the TP8 (modem/driver issue).

Well either could be dodgy drivers, or simply all the card is capable of. I dont know how you would get the exact specifications of the LTE chip, the drivers are provided by Microsoft so you might just have to wait for an update.

 

https://docs.microsoft.com/en-us/windows-hardware/drivers/network/mb-interface-model

 

Or try and find a utility which will tell you exactly what the LTE chip name is.

Re: Yoga Book Very bad LTE speed

OK not sure of it helps, but this is what I get about what modem is in use:

 

Name : Cellular
Description : CDC MBIM
State : Connected
Device type : Mobile Broadband device is embedded in the system
Cellular class : GSM
Device Id : 86971402011xxxx
Manufacturer : Intel Corp.
Model : CDC MBIM
Firmware Version : BLADE7260_MBIM_ES3_01.1625.00
Provider Name : DNKTD
Roaming : Not roaming
Signal : 74%
RSSI / RSCP : 23 (-67 dBm)

 

Anyway, I was also hoping that someother people in this forum with an LTE version of the YogaBook, could perhaps do a SpeedTest.net measurement over LTE and report back what speeds do they get. As you say, maybe that's all what this hardware can.
