Hi Sifus,

Just upgraded to 800 unifi. Router is Tp link AC1200 by Telekom. Bandwidth set to 80. 5ghz connection with channel selection @ 48. Checked with wifi analyzer...no overlapping with neighbors @ this channel 48.

My phone is Samsung A51 Exynos9611, 8mb ram & Android  11.

Using Speedtest my wifi max speed I got is 250 with phone about 1ft away from router. Using cable connection with a laptop can reach 800. May I know at what max wifi speed my phone should be abled to get with this router by Telekom?

I was thinking of getting the tplink AX73 AX5400 to replace the existing router. With this new router will it give a max wifi speed of up to at least 350 maybe up 500 lol.

Thank you very much for your kind understanding and cooperation. 

Thanks

First of all, your phone only had 1x1 antenna which means the fastest speed you could get on the 5GHz is 433 Mbps (especially your phone doesn't support wireless AX). Higher end phone typically comes with 2x2 antenna which could go up to 866 Mbps for AC and 1201 Mbps for AX. So far I don't see any device with more than 2x2 antenna configuration due to space constraint in the phone.

Upgrading router probably doesn't do any good as you are limited to 433 Mbps because:
1. Your phone only had 1x1 antenna configuration
2. Your phone only support up to AC

I changed my router from tplink archer AC1200 supplied by TM to Tplink AX5400 archer A73 which I bought. Previously my Samsung A51 can get 250mbps down. My unifi is 800mbps. Now with the new router can get  335mbps down. Increase from 250 to 335.

Now the problem is cannot connect to my Xbox Series S using lan cable to this new router. Previously with the old router was abled to using lan cable. Btw there was no problem connecting using WIFI with the new router.  Help will be much appreciated. Thank u very much.

Did you connect the ethernet to the port that was meant for IPTV?

You could find out the port assignment in the router setting under the VLAN settings. Typically it's either 1 or 4. It seems like you had plugged it into port assigned for IPTV.

I didn't realized for the Archer A73 IPTV is Lan1 lol. I don't have IPTV cause my package comes with only Internet.
And I noticed Lan4 is VOIP.  So only 2 Lan ports for internet use. 1 is for Xbox and the other for Desktop computer. I wanted to use Lan4 for Android TV but don't know how to configure for internet.

From the Emulator, it seems you could select it manually. Give it a try.

Hi sifus,
need help or any solution on this, technician has came for the third time and issue hasn't been resolved.
I subscribed to celcom 500mbps, when I stand near to wifi 6 router I managed to get around 500+mbps. However, when I turn on my mesh wifi, I'm only getting around 300mbps downstairs and only 150-200mbps upstairs. I have tried to turn off the router 6 WiFi and just focus on mesh wifi to prevent any signal interference but still the same result. Is mesh wifi able to maintain the speed of 500mbps?

router - tplink ax3000
mesh wifi-deco x20

Are 5GHz channel specifically channel 36-52 and 149-165 crowded? Your router had the capability of using DFS channel which could avoid crowded 5GHz channel but Deco X20 likely can't use DFS channel.
