ER605 v2 x wireless AP
Hi everyone,
Let me make a brief and describe the situation.
Router: ER605 v2, firmware 2.2.2 Build 20231017 Rel.68869.
MTU = MRU = 1492
MSS clamping = auto
PPPoE
The modem with fiber optics connection is running as bridge. The MTU value recommended by the ISP is 1492.
Access point: GPT-2741GNAC-N1-SV (it is a fiber optics modem/router no longer used. It is set DHCP off and no NAT. It is working only as AP providing both 2,4 and 5 ghz connection).
The problem: some apps on smartphones connected to wifi do not work properly (like Twitter media, for example). This problem only happens on cellphones. When I run the same on computer also connected to the wifi, no problem. Also no problem while using cable connection.
I read that it seems to be related to MTU settings, however I did not find out how to adjust it correctly yet.
Everything worked fine before installing the ER605 that replaced the ISP router.
Thank you!
