DECO XE75 pro unusable 2.4 Ghz network
DECO XE75 pro unusable 2.4 Ghz network
I have a network composed by 3 deco xe75 pro and one deco x50. My 2.4 Ghz network is unusable (packet drops, high latency, continuous disconnection of IoT devices).
I've done a scan of wifi and found that deco often chooses a channel used by other networks, and channel width is always 40 Mhz. The only way I have to reduce interference is to reduce channel width to 20 Mhz, but I can't do dat with the app. Can you help me?

Hi, to assist you efficiently, I've forwarded your case to the TP-Link support engineers who will contact you later. Please pay attention to your email box for follow-up. Thank you.

Hi, it is a pity to hear that.
We have consulted the engineering team to take further analysis on your feedback, now it may be too late.
Anyway, sorry for the inconvenience caused.
Thank you and best regards.

I have received an email from the support team with a link to a beta firmware. I applied the firmware on Saturday morning and comparing the fast.com speed test the results are much better.
Before beta firmware:
Download 24Mbps
Upload: 12Mbps
Latency unloaded: 7ms
Latency loaded: 385ms
After beta firmware:
Download 45Mbps
Upload: 24Mbps
Latency unloaded: 12ms
Latency loaded: 261ms
I have also noticed an improvement in the responsiveness of IOT devices using the 2.4GHz channel, I will continue to test and monitor the situation but so far the results have been much much better.

What's the version and build number ?

Hi,
I had a similar issue with my 3x XE75(V1), and the beta software that I used, changed all the 2.4GHz channels on the 3x XE75 satellites to use different 20MHz channels; instead of 40MHz, so they wouldn't interfere with each other. Since then all my IOT devices have never dropped and latency is also much improved 
TP-Link now need to add the new features to all their software, so that everyone can enjoy the benefits?

Having the same issue with my XE75 network (not pro).
No option to change width of 2.4ghz connection. The drops are insane, my smart devices all complaining about lost internet.
40mhz has way too much interference in my home, and if it would simply allow us to force 20mhz this would fix the issue.
I saw some had a beta firmware emailed to them - would support be able to send me one for my model? (XE75). If this feature is not implemented I'm going to need to look at another solution. Right now 2.4ghz is not viable.

Raise a fault ticket with TP-Link and ask for Beta software, which changes the individual 2.4GHz satellite channels/channel bandwidth? So there is limited co-channel interference.
