Model: CPE220  
Hardware Version: V3
Firmware Version: CPE220(UN)_V3_2.3.3 Build 20250704

hello

 

after upgrading the firmware on my cpe 220, i began experiencing connectivity problems, the device works normally for about 15-20 minutes, but then it loses the internet connection from my AX1500 access point. when i attempt to connect cpe 220 with my phone or PC , i receive the error "could not obtain IP" in that time i am not able to access the web interface , if i turn off and turn on , again start working for some time normal , then after again same problems.

 

config : cpe 220 in bridge mode receiving internet from AX1500 router working in access point mode and providing internet to tapo camera

 

i have in my hand one brand new cpe 220 bought for one of my friend , i took that one adaptor to see if there is problem with adaptor , again had the same problems , i checked all cables , eveything is fine.

 

so i installed brand new one with old firmware 2.2.3 build 20201028 rel 55382 and all system working fine.

 

as far as i understand this problems coming from upgrade but unfo i can not rollback the earlier firmware , i also tried TFTP

 

I have seen a beta release of new update shall i try that one , or is there any other suggestion ,

and if i try beta release and if things will get worse will be any problem with warranty?

 

thanks in advance

Hi  @Tifone 

 

Thanks for posting here.

 

Please test with different channels of the main router, this may caused by wifi interference.

 

What's more, we don't recommend using CPE products under bridge/repeater mode.

As for the pre-release firmware, yes, you are welcome to update it, and it may help.

  @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

Hi  @Tifone 

 

Did you download the pre-release version from the following link?

https://community.tp-link.com/en/business/forum/topic/833578

 

It's for CPE220 V3, is your device V3?

 

If so, please also try with different web browsers, and private mode of the browser.

  @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
