Constant LTE disconnects - Archer MR200 & MR600
Initially I was using a MR600 for a couple years with no issues, then we started to get regular drops. I followed numerous posts on here and tried all the different "fixes" but nothing worked. Eventually it was so bad I just went out and bought a brand new modem. Unfortunately our local tech store only had another TP Link router in stock (MR200) but I thought with it being new, there shouldn't be the same problem.. I was wrong. Not even a few days in and we are starting to experience the same thing. The router just drops the connection for no reason.. Today I also ordered a new sim card (EE) so will be testing when that arrives. I haven't uploaded the new ISP file to the MR200 yet, thinking that because the router is brand new, there shouldn't be a need!? Or am I wrong here?!?
Here are screenshots of connected.. and not connected..
Can someone please advise on next steps here. I cannot believe that a brand new modem is faulty in exactly the same way as my old one!!
