@Miles:
Thanks for info!

Personally I'm not in that hurry since I rooted the device and removed all unwanted apps and the battery optimization tweaks gave me easily day and a half of normal usage.
Please devs, check all possible battery opmization tweaks before releasing the final ROM!

Thanks Miles. I did not. I only related to you my own observation and exprience. Maybe you can recommend a good wifi test app for me.

AS: Search through older thread in the Forum, WiFi has been already discussed.

General considerations (improvements for the home/office WiFi Access Point)

- 2.4 GHz has better penetration through the walls, and longer-distance access but to the other side 5GHz is faster, and there is a chance for less overlapping and interference from the neighbors on 5GHz.

- Configure your WiFi AP (both for 2.4 GHz and/or 5GHz) to u use 802.11 n (only). Use backward-compatible 802.11 b/g/n only if you have old devices not supporting 802.11 n.
Similarly, configure the encryption to WPA2/AES and use backward-compatible WPA/WPA2 (forget WEP) only if you have old devices not supporting WPA2.

- Applicable only to 802.11 n:
Configure 2.4 GHz to span over 40 MHz (coupled channels), instead of default 20 MHz bandwidth.
Configure 5 GHz to span over 80 MHz, instead of default 40 MHz (or even less 20MHz) - on some WiFi Access Point you must set to Country: US, to have this option enabled.

- Both on 2.4 GHz and/or 5GHz, inspect (see for the tools below) which channels are less overlapped and instead of Auto, configure your AP to use specific channel with the less interference.
But prefer also lower channels, since lower frequencies (longer wavelengths) provide better penetration.

If needed, buy a new/better Access point, I've recently purchased a five-antennae monster (for less than 40 bucks, now the price is almost 50 by the same seller):
https://www.aliexpress.com/item/English-Firmware-FH1202-Wifi-Router-Signal-Strength-Repeater-1200Mbs-AC-Dual-Band-Wireless-WIFI-Router-Tenda/32299252497.html?spm=2114.13010608.0.0.FpLD2C


Use the following tools (listed Android tools are available from Google Play):

1) Speedtest.net by Ookla: To measure download and upload from/to Internet. Speed depends not only on the phone and WiFi, but also on your firewall and (greatly) your Internet connection.
Use the corresponding Web tool on the PC, preferably wired directly to your router, and measue the corresponding Internet speed on PC - if slow, complain to your Internet Service Provider, or take a better one.
With a well configured WiFi (see above), WiFi Internet speed must be close to the measurements from a PC on the LAN.

2) WiFi Analyzer by farproc: To graphically inspect overlapping with the neighbouring WLANs on 2.4 and 5 GHz channels (and more useful options).

3) WiFi Speed Test by Zoltan Palagi: In parallel, download and run (no installation required) wifi_speed_test_server.exe from https://bitbucket.org/pzolee/tcpserver/downloads
on your PC wired directly to your WiFi AP.
Unlike in (1), you measure here download and upload speed purely on your WLAN (Smartphone on WLAN <-> PC on LAN).
Run the same test from another smartphone or WiFi gadget, results from Ulefone Metal must not be worse (?).

IMO, Ulefone Metal is very good on 5GHZ 802.11n, you can go up to 80-85 Mbps with tests (3); while with 2.4 GHz 802.11n you probably can't get better than to cca 50 Mbps.
If you have a comparabe speed by your ISP, it's more than enough to watch video streaming.

Do really the Ulefone Metal have 5GHz Wifi?
The specifications page seems to indicate that only supports WiFi802.11 b/g/n 2.4GHz. http://ulefone.com/products/metal/spec.html
I can't try it since only own a 2.4GHz AP, so it does not  matter much to me anyway.

Again, take some time and search through knowledge (screenshots and measurements by other people) contained in the older threads

Yes, it does support 5 GHz, uploading here my WiFi Speed Test (tool 3) screenshot from my home 5GHz 802.11n WLAN (by using ny new 5-antennae Tenda AP).
And another screenshot just taken now in the town, from WiFi Analyzer (tool 2), showing no-overlapping on 5GHz (this particular 5 GHz 802.11 n WLAN does not span over 80 MHz but only 40 MHz).

Btw, you can install WiFi Analyzer and take a tour throgh your neighboarhood, there is a good chance you will spot 5 GHz WLANs, to see that Ulefone Metal does support.

OTA went fine even though phone is rooted!
Installed update (takes a while) and realized that root is gone...

But don't worry;
Just install SuperSu binaries via TWRP and You're ready to go again!
