I recently took advantage of EE's "double your data" offer on my EE Huawei wifi dongle (64GB for £28/m). But when I put this SIM into my TP-Link Archer MR200 4G router I get no connection. The router throws up an error message saying "check you configuration." I have tried the standard APN settings used by my EE wifi dongle, plus various other combinations but with no luck. Could it be that EE is refusing to connect to a SIM in a third party router? The same router worked fine with a data SIM from 3 which I tested a few months ago. Anyone else had an issue similar to this?
The APN settings I was using, among others, was as follows
APN - everywhere
username - eesecure
password - secure
authentication - I tried with both PAP and CHAP but with no luck
