TP-Link Powerline Utility Not Working (Very Recent Problem)
This thread has been locked for further replies. You can start a new thread to share your ideas or ask questions.
I have searched everywhere for a solution but found nothing that resolves the problem, plenty of suggestions but none work for me. I have tried absolutely everything! Until a few days ago the utility worked fine - here is my network showing correctly...
This is all I get now...
I have reset my computer's date to before 12 Jan 2021, installed npcap in place of winpcap, reinstalled the utility over and over, turned off all AV activity (Kaspersky and Malwarebytes Pro). I have a variety of TP-Link adapters and they all work fine, as do the devices attached to them either by cable or wi-fi, it's just the utility that doesn't work.
Something fairly recent has obviously happened - an update to Windows or another program maybe? Everything else on my computer is fine, no problems at all.
Any updates on the previously reported solutions? Thank you.
@Solla-topee I have reinstalled the utility many times, from different sources to eliminate a rogue file, completely removed all traces and reinstalled. It makes no difference but I have identified the cause, it is definitely having more than 7 adapters - 8 actually including the "input" one.
That seems to be a magic number according to your own list of the number that can be installed, albeit the minimum. According to that list ( https://www.tp-link.com/fr/support/faq/434/ ) I should be able to have 16, assuming the number is limited by the slowest/oldest unit. I have...
5 x TL-PA8015 (one "Lounge" is the "input")
2 x TL-WPA8630
3 x TL-WPA4220
Those below in green are all working and the TP-Link utility is working. Those in red are not plugged in and the moment I do so the Utility fails.
It does not matter which CPLs are plugged in, it it just the number, more than eight including the input "crashes" the Utility.
To find out if it is the slower CPL's limiting my network I have ordered 3 more TL-PA8015's which I will use in place of the older TL-WPA4220's but if the same problem occurs I will send them back. I do not have the need for the speed, they are used for cameras and the slow ones work fine.
I would really like to understand why I am unable to have all 10 of my adapters work together. Thank you for your assistance.
