EE Sim + 4G Router constantly dropping internet connections, DHCP issue?

[taledega32]

I recently bought an Asus 4G-AC68u Router for gaming and home use when I travel around the UK.

To test the router I used a GiffGaff sim with 80GB of Data and it was fine over the space of a week, no connection drops, however the average speed was 12Mbps.

Now today I got a EE 200GB sim card and inserted it into the router and did a full reset, the connection speed is around 70Mbps which is great.

However the internet is constantly dropping and not persisting.

Here is an output of logs from the router

Here is a screenshot of the routers 4G WAN settings (it autoconfigured the APN)

Asus 4G AC68U WAN settings

I believe the issue is at the network level (TCP/IP).

What settings would you recommend for me:

* LTE Band -  (B1,B3,B7,B20.B38)
* PDP Type - (IPV4, IPV6, PPP, IPV4&IPV6)


Do the APN settings look ok?


Things I have done:

* Upgraded the firmware
* Tested another 4G sim (Giffgaff - O2, Virgin Media - EE)
* Checked the signal, full strength and line of sight with transmitter


Is EE kicking my router off its network because its not an offical EE 4G router?

Any ideas

Hi @IanP29 ,

You may wish to do a search online with the below search terms.

It seems to be a common problem and may have a solution or workaround by now which could involve a different version of firmware.
