@Vincent-TP Many thanks for your kind reply , however i didnt know it was not recomended to use as bridge/repeater mode ,

and as this modes was in quick setup and i was using very happy till last update.

and as i advised another cpe220 with first firmware i.e CPE220UN.V3.20201028 still working very stable.

i tried different channels as you advised in main router unfortunetly again same problem

i will update firmware with pre-release and hope this will fix

i wish i have chance to return first firmware but looks unfo no any chance

i will keep you informed if pre-release will help

thanks in advance

  @Vincent-TP i have tried  loading prerelease unfo not able to do , screen picture as attached

  @Vincent-TP  yes i did

  @Vincent-TP yes i have loaded from that link

i took the risk and tried to upgrade the other cpe220 in my hand with same file (prerelease)

upgraded without any problem , i hope i will not have same connection problems while using

in bridge mode.

the problematic cpe 220 i tried as you mentioned another browsers / private modes etc

unfo not accepting file , what i have noticed is cpe 220 only accepting the firmware file which 

is inside , not accepting any other firmware i.e screenshot as attached.

what i have tried is

- loaded firmware given link from 3 browsers

- tried to upgrade with 3 browsers 

unfo always same not accepting file

pleased to hear

  @Vincent-TP  hello

equipment is bought may 2025 under waranty but today i tried to reach tplink unfo i couldnt get support

because i am using this equipment as "single" they say because of that this problems,

i told them i can not update with pre-relase etc they didnt accept.

they are saying cpe 220 can not be used as sole equipment should be twin , this equipment

can not be used as access point , bridge , repeater etc etc.

but i was using till firmware update.. anyhow to update my last situaiton

- new cpe 220 updated to prerelase firmware, new  equipment start stoping

  on brigde mode ( as far as i undestand in recent firmwares something

preventing cpe 220 to work as bridge mode) so installed new cpe 220 as access point

with cable bewtween ax1500 and cpe 220 , working fine .. but in every 6/8 hours stop 

working and need to reset , so looks i can not use anymore cpe 220 as single equipment efficiently

could you please suggest me is if eap 225 or ?? is right equipment for my senario

(ax1500) - cable- (eap225) - wifi - (tapo camera-distance 30 meters) + (home user  3 person mobile phone/computer/tv distance 30 meters)

thanks in advance
