Empty top-interference and lots of packet drops
Team,
Over the weekend I have upgraded the WiFi network from three EAP245-v3 to three EAP653-UR-v1.
Compared to the EAP245 setup there are some strange differences:
(1) - the top interference content block is empty. With the EAP245, this was filled with the 3 EAP's and a certain percentage.
(2) - high drop rates - sometimes over 60% for longer period of time. With the EAP245 this was zero all the time.
(3) - clients seem to be sticky and don't select the best possible EAP. This was not the case with the EAP245's.
Regarding (3):
At site level I have always enabled, fast roaming, AI roaming and bandsteering for 5-Ghz.
Enabling the non-stick-roaming and rebooting the EAP's doesn't seem to give any improvements.
The EAP's are all set to auto for wireless mode, channel-width and channel.
According to the controller, the wlan optimization is not available for 2 EAP's because of the mesh connection between the 2.
Meaning one is connected via UTP and has a mesh connection to the other.
I tried to increase and dcrease the transmit power of the radio's and rebooted the EAP's.
Which improved things a bit - but sill no top interference and still high drop rates.
I'm ware that troubleshooting these kind of issues can be challenging.
It's just that it looks as if the EAP245-v3 is far more stable then the EAP653-UR-v1.
Any suggestions?
With warm regards - Will
Thank you for your quick response and to the point questions - great!
(1) - See atttached image: this is the top-interference block as I see it in de local Omada controller.
This applies for both tabs - 2.4-Ghz and 5-Ghz.
(2) - I understand - calculation method is important - also because I don't believe an all zero's all the time.
(3) - below some more details.
Yes - all 3 EAP's are in the same building and about 15-20 meters from each other.
All 3 have low settings on transmit power:
* 2.4-Ghz: custom with a value of 9 (same as EAP245)
* 5-Ghz: low (same as EAP245)
Reason for this setup is the thick walls and HR++ windows between the 3.
All wireless clients have the same issues. What worries me most is the drop in client signal strength as reported by the EAP.
On average the EAP245 reported a client signal strength of 60-dBm. While the EAP653-UR reports an average of 70-dBm.
Since this is a drop-in replacement (i.e. everything else being equal) it is not something I would expect.
However the 653-UR is smaller then the EAP245 - most likely because the antennas are smaller. With the site-effect of less signal receiver coverage. With that in mind: would the EAP683-UR be a better choice? Since the device is even bigger then the EAP245 and also has more antenna's it may have a better signal receiver coverage?
What is your view on all the above?
With warm regards - Will
