Can I suggest you report any bugs you find to tp-link? I have asked tp-link when the next update will be and they didnt seem to know. I asked support to tell the developers to release more updates....

Hi Mike I was away from home when I saw your message, and was concerned that EE had broken the MR200 again. However my MR200 is working just fine on EE, no problems at all. I am using the beta...

all fixed?

Its none of those. Its beta 161026, file starts Archer_MR200v1_0.9.1_1.1_up_boot(161026)

I have been using an EE sim card with the MR200 with no connection issues.

have you tried updating the new firmware or contacting support?
