TP-LINK TL-MR3020 + E3372 dongle

Hello,

many thanks to all of you who are involved in this project. It’s great to see this little router is getting LEDE support.

Also, are there any known compatibility issues when using TL-MR3020(EU) V3.0, this Pulpstone/LEDE FW, Huawei E3372h and LTE FDD B20 (Band20, 800MHz)?

When i connect Huawei E3372h (HiLink) to TL-MR3020 with stock TP-Link FW it keeps dropping internet connection on LTE B20. If I use this combination on LTE B3 coverage (Band3, 1800MHz) all is well.

So I am about returning TL-MR3020 or flasing it to this Pulpstone/LEDE FW.

If I connect E3372h on LTE B20 to PC, Asus RT-N16 (stock FW) or RPi3 (ROOter FW) internet connection works without problems. If i connect E3372h to TP-Link TL-MR3020v3 (stock), TL-MR3220v2 (stock and ROOter) or Asus RT-51U (stock), connections drops after few seconds. When I’m on LTE B3 coverage, all mentioned routers works OK. I tried on different locations with two different mobile operators - situation stays the same.

Thanks for your help!
