the Group Key Update Period is set at 0 for both 2.4 and 5 GHz. i noticed the wifi encryption was not set at auto(recommended) for both so i changed it. hope this solves the issue.

Hi guys,

I'm using Archer C5 now and just got upgraded from unifi 30Mbps to 50Mbps. since then, the speed has not been consistence. Before that I can easily get 30Mbps easily on both 2.4G and 5G but ever since upgraded, I only managed to get 20Mbps for 2.4G and 30Mbps for 5G even though the signal bar shows 4 bar for 2.4G and 1 bar for 5G. how come like that as 2.4G is showing a stronger 4 bar signal compared with 1 bar signal/5G yet the speed for 2.4G is so slow? I have disabled both the IPV6 and Bandwidth control but that doesn't seems to help...

It sounds like there might be interference or congestion on the 2.4GHz and the 5GHz around your location, that could be due to moreof your neighbours using Wifi now. Use a wifi Analyzer app on your phone or download a Wifi Analyzer on your computer. I would suggest the Wifi Analyzer app by farproc on your Android app or Acrylic Wifi for your computer.

Theres no correlation between getting a stronger signal on 2.4GHz and a faster connection. 2.4GHz has better range, but with lower thoroughput, but it’s usually very congested and prone to interference. 5GHz is usually better, with higher thoroughput, to the expense of range, but less congestion.

ok, just downloaded the wifi app by farproc, will check again tongiht. Thanks for guiding

TP-LINK MY, how to setup printer server if want to print using Android device or Ubuntu PC?
HP got provide plugin to detect printer but it cannot detect the printer server.
https://support.hp.com/gb-en/document/c04024231

Device is Archer c9 v1.
Printer is LaserJet M1132 MFP.

Does the Archer c9 printer server have it's own web interface?
If yes, what's the IP? i already change the router's LAN router range from 192.168.x.x to 231.27.x.x What's the printer server IP for my config?

I think they did provide low-profile bracket now on their PCIe wifi adapter, you can check on their packaging, there is a sticker on it.

example:

Archer C9 print server function currently just support Window and Mac, you can check the compatible list at below link.

For the Archer C9 print server, there is no own web interface.

Ohh okay thanks, will check it out at stores.

where to get TPLINK TL-MR6400 LTE antenna?

Just got my hands on TP-Link Deco M5. Gonna test it out real soon.

Feel free to ask me anything regarding this device.

Exactly the same issue as mine.. same c5 and upgrade from 30 to 50mbps.. only thing is even my LAN connection also slow... dunno whether router or unifi problem

Thanks for the reply.
Will we get updates for wpa2 encryption?https://www.google.com/amp/s/www.lowyat.net/2017/144873/wi-fi-wpa2-encryption-possibly-cracked/amp/

I will be switching firmware if software support has ended.

as usual give us some in depth review.

Try disable IPv6 completely and only running on IPv4.

See if it is Unifi IPv6 problem...

Thanks to bro SilentVampire, followed your guides and below is what I get...

for 2.4G, no channel congestion, signal strength is 4 bar but no matter what channel I set, speed still sucks, give up liao


for 5G, also no channel congestion, signal strength is only 1 bar but routers default the channel to 153 which caused the speed to drop drastically but after I set to use channel 44, I managed to get full speed



based on most forumer's recommendations here, try to disable both IPV6 and Qos(Bandwith Control) first. Best is you use a cat5e cable to test. by right if LAN also not giving you full speed, you will need to call TM, they are obligated to get it fixed for you, good luck

The app can only scan those wifi complaint network but they are a lot more other devices hogging the 2.4Ghz band.

Dect phones, microwave ovens and even some baby monitor all use 2.4Ghz

I’m quite surprised to see that 2.4 is still so bad. Try changing to 40MHz for your 2.4GHz. That might help.
