Out of interest are you seeing large amounts of dropped packets or retries on the EAPs in the statistics tab on controller?

I'm seeing simular issues where I can't ping between wireless devices but can ping my switch, router and the internet and some wireless devices seeing general degraded performance. I then saw that there was a lot of dropped packets. After some further checks I ended up rebooting the EAPs and it returned back to normal.

Today simular but this time large amounts of retries, again rebooted the EAPs and back to normal.

Might be related maybe not. Thought I'd mention so you can check this area. I've only noticed this on the 1.7.0 Build 20200703 Rel.59609. No problems were seen on the old OC200/EAP firmware.
 

1 x OC200 

1 x EAP225 outdoor [1.20.0 Build 20200422 Rel. 70543]

1 x EAP225 [2.20.1 Build 20200630 Rel. 41064]

I triyed to reboot each EAP and after that I'm able to ping the wireless devices.
I suppose that such behavior is a bug?

@BeppeTPL 

That is interesting and I would say it is a bug. Question for TP-Link or other community members that may know. How do we report this bug?

Also did you check the statistics for the eap's on the controller? To see if you had large amounts of dropped packets or retries on the EAPs?

@JD792 

Yes there are a lot of dropped package. 

This is the current situation:

Is that like what happens to you?

I don't know how to report this BUG to TP Link.

Thanks

@BeppeTPL 

What was it like before you rebooted your EAPs? Didn't you rebooted them on the 19th Nov?

This was how it was for me last time this happened. You can see the issue started around the 16th October and got worse over time and resolved on the 29th October when I restarted the EAP's. I have reported it to TP-Link to their tech support email and I also mentioned this community thread.

@JD792 

Starting from the 20th of november I've implemented a daily reboot in order to avoid the issue.

The result is negative, I set the reboot at 03:00 am but at the 10:00 or 12:00 am the issue is present again, it work fine only for some hours.

I don't know how to solve it.

thanks 

@BeppeTPL 

You seem to be affected a lot more by this than I am. I haven't seen it since the first time in October. 

I would recommend emailing TP-Link Support <support.uk@tp-link.com>, I've been speaking with Kayla.Song. Keeps us updated!

Hi,

When I had the issue it was on my normal SSID not my guest. Same devices use the wireless environment and there was no other change in the environment. EAPs have not moved. I used the old firmware for the OC200 and the EAP's before SDN was released and I never had this issue. I think my EAPs are on 20mhz and channels are set statically. Normally I don't see any dropped packets and have gone many days and then suddenly the issue presents itself and there is a massive and noticeable amount of dropped packets. When looking at the graphs it looks very abnormal. If it was the wireless environment I would expect the same amount of dropped packets throughout. Graph below shows when it last happened to me. Shows before and after up (when I rebooted the eap's to till present day.)

I believe this is a bug in the 1.7.0 Build 20200703 Rel.59609 controller firmware or on the EAP's firmware.

@Fae 

After reboot I'm able to see the printer, to see the other devices like iphone, smart deivce (plug, lights...).

As indicated in the FAQ I configured the Wi.fi parameters fixing the channels, power and channel width, the result is the same.

Here in the following the situation of yesterday

It worked fine till first afternoon and then the devices was isolated again. I also tried to reduce the power but the result is even worse.

For me it is problem of the Omada SW, I don't know how but at the beginning my network (composed of only two EAPs) worked very good and I never had such problems. When I installed the OC200 the problem came up. I'm thinking that there's some internal logic that doesn't work properly.
