just gotten TP-Link Archer AX20.

been trying to setup Unifi, but encounter unknown issue with WIFI

Enabled OFDMA and Smart Connect (combi 2.4G/5G in 1 SSID)
WPA2-PSK and AES (default)

laptop connection ok, but Xiaomi Redmi Note 8 handphone wifi not ok. able to enter wifi password, but somehow the phone doesnt recognize any internet connection.

From WIFI settings (phone), the status just saying "Saved". But unable to resolve for internet connection.

I reconnect back to old AC1200 (existing Unifi), phone connected to Wifi (5G and 2.4G separately).


any specific setup for AX20 that need to be aware of? or some settings that might not be compatible with phone's wifi detection?

thanks


*update: managed to solve the issue. somehow the phone doesnt work if version=WPA2-PSK and encryption=AES exclusively. after changing to version=WPA-PSK/WPA2-PSK and encryption=TKIP/AES, then only the phone wifi can work

yep

speaking of TP-Link Archer AX20, some devices may not compatible with the wifi if you setup 5Ghz Mode=802.11a/n/ac/ax (mixed)

eventhough it's backward compatible, some devices (non-AX support) doesnt recognize the 5Ghz wifi channel.

setting to 5Ghz Mode=802.11a/n/ac (mixed) --- without ax, the device would then recognize 5Ghz wifi from AX20.

recently bought TP-Link Archer AX20.

or can try AX50 which is a bit more. got 1 seller in Shopee gives a good deal.

how did u solve it?

for me, I changed tp-link router mode to AP/BRIDGE mode, then only can use with HG8145 combo onu+router

still finding how to do it on HG unit.

changed the tplink setting, not the Huawei unit

need some suggestion

currently using AX20 with Time Fiber 100mbps. AX20 set as Bridge Mode <--> Time's Huawei HG8145V5 router+BTU.

Firmware Version: 1.3.1 Build 20210521 rel.72481(5553)
Hardware Version: Archer AX20 v1.20

intermittently, some of my devices cannot connect to 5G. could it be too many devices connecting to the router?


i've split some devices to 2.4GHz (Channel: 1, to avoid majority of nearby wifi connections in my condo )

1) smartphone #1
2) xiaomi cctv
3) laptop #1 (old, cannot support 5GHz) -- when doing MS Teams, connectivity would drop
4) previously smart tv connected to 2.5GHz, but i suspect congestion at 2.4Ghz, so i switched it to 5GHz)


5GHz devices (Channel: Auto, Current: 149)

1) smartphone #2
2) laptop #2 (newer, can support 5GHz) -- some times auto-disconnect, need to manually connect back
3) laptop #3 (newer, office laptop, can support 5GHz) -- only use during WFH hours
4) smart TV (previously 2.4GHz)



if i upgrade to AX73 or AX90 (may be overkill), would it help to improve connectivity?


thanks!

ax20 as bridge

no change to HG, but I disabled its wifi since I'm using ax20 wifi anyway

i see!

if Huawei in bridge mode, does AX20 need to be in bridge mode too?

yep, no issue with pppoe credentials

thanks for the suggestion

AX72 better?

maybe can disable QoS or Parental Control?

or temporary remove Guest Network (wifi)

i was also confused with ax55 vs ax72 (even after read your reviews )

seems like almost comparable, but am sure ax72 has some advantage over ax55 (in terms of wifi performance)

thinking to upgrade from AX20 to AX73.

any good deal lately?

now, price hovering rm459 on a good average price in shopee.

not bad for the price!

wahh, kinda overkill, but with that price, really ok

with promo price, dont mind the price

with RRP, kinda steep for general WFH, daily household use.

the ax72 used before? somehow it retain old settings.

try do router reset, then follow the wizard to setup unifi pppoe.
