Weak Wifi Reception?

My DMAF5 strains to get this --

500

But my OnePlus 6T in the exact same place gets this --

501

I am running the latest Wifi Driver from Intel.

UPDATE

It turns out the test servers were not the same in that app. So sometimes the reception would be better. Still -- I sense this is a little slower somehow. Does anyone concur or is it just me? (It could be just me, lol.)

Ciao MiniManiac e a tutti del forum;

Ho fatto una prova con il dispositivo Wi-Fi del DMAF5 e in pratica si connette ad una velocità 0,4 in download.

La frequenza di connessione è 2,4 GHz ma il modem supporta anche la banda 5 GHz.
La mia connessione di rete casalinga arriva al massimo a 29 Mbps download e 10 in upload.
Non mi ero accorto del problema perché avevo la connessione con cavo Lan di rete.

Ho guardato se ci sono problemi di firewall o altre cose che possono creare problemi ma non viene rilevato niente di anomalo.

Hai qualche idea per risolvere?

Grazie

@MiniManiac I switched to wired for this exact reason. At the time I was more bothered by the fan noise so didn't investigate further. I'll do some tests and let you know

OK. Tested by running speed test comparing iPhone and DMAF5 in exactly the same location

iPhone 300+mbps download
DMAF5 82-100mbps down

I only have a wifi 5 capable access point. I'm not sure if that's the issue as DMAF5 does have a wifi6 wireless card

Another note I made was where the download speed for DMAF5 is 80-100mbps the UPLOAD speed is 120mbps which is exactly where it should be.

DMAF5 WIRED (via poweline) is 300mbps+

My Google Wifi access point is about 8 feet away from the DMAF5 with clear line of sight.

Grossi problemi con Wi-Fi, in pratica la mia rete funziona con 2,4 / 5 GHz ma il DMAF5 si aggancia a 0,4 in download, quindi non funziona.

con cavo di rete nessun problema.

Ho aggiornato i driver ma nessun beneficio.

su altro 3d, con Ryzen 3 sembra che ci sia lo stesso problema di Wi-Fi.

Chiedo formalmente un aiuto agli amministratori del forum per risolvere il problema.

grazie

Since the AX200 is an intel’s wifi6 wireless network card, if there is a network connection failure or other problems. I suggest to update to the latest driver or go to Intel forum for help. Or you can try to find other M.2 network cards to try, or you can adjust the settings of the network card according to the following methods and test it.

I also have problem with weak WiFi reception. My desk is about 2m from WAP (11ac) and DMAF5 usually only connects at 11n. My Lenovo laptop with Intel 11ax adapter connects at 11ac. I think the WiFi antenna are shielded by metal case. Please can you show how to improve placement of antenna on plastic lid

I have the UM300 and its wifi is also less than stellar. Making the changes to the 5 GHz channel width helped, but compared to an external USB wifi adapter (even a nano adapter with no external antenna) the internal wifi is poor. The nano USB adapter pulls about 200 - 250 mbps down, while the internal wifi maxes out at around 100 mbps. I do believe there is some interference emanating from the box, however, because I've tested the nano USB adapter in the front USB port and it gets 200+ down, but the same adapter in the rear USB port often has trouble connecting at all, and if it does, gets < 100 mbps down. Even with the machine turned around on my desk, using the adapter in the rear USB port results in lower wifi speeds. I believe something in the box creates some interference on the rear side of the device. If I use the nano adapter plugged into a six inch USB extender cable (3.0) and plug it into the same rear USB port, but run the cable so the adapter is in front of the box, the download speed is closer to 200 mbps. So it seems there's something near the back side of the box that generates interference with wifi. Although I haven't opened the box to look, my guess is that the internal wifi antenna is probably somewhere in that location and that's why it gets substandard performance. Note: all external wifi adapter tests were done with the internal wifi adapter disabled in Windows network adapter settings.

So I decided to open the UM300 and check the location of the antennas from the internal wifi card. I was guessing they might be near the bottom, but was surprised to see they were located at the top of the box, so I wasn't sure if their location was causing the speed issues. Just for kicks, I removed the one attached to the rear and moved it to the top/front of the box next to the other antenna (I had to move the other antenna over a bit to make room for both. Anyway, when I tested my speed on 5 GHz using the internal wifi card after moving the antenna, my download speed jumped to nearly 300 mbps fairly consistently (always > 250, sometimes reaching 350, usually around 275-300). Since I've never seen this level of performance from the internal wifi to date, I must assume the positioning of the antenna in the back/top of the box is not optimal, and moving it to the front/top is much better. My 2.4 GHz speed is still fairly poor however, only reaching about 35 mbps on average. I spent a couple of hours installing the latest drivers, changing various settings, but I couldn't improve upon these results..

For what it's worth, my adapter settings are set to:
802.11a/b/g wireless mode = Dual band 802.11a/b/g
802.11n/ac/ax wireless mode = 802.11ax (my access point is 802.11ac)
Channel Width for both bands is set to "Auto"
MIMO Power Save Mode = No SMPS

And on the Power Management tab, be sure to disable "allow the computer to turn off this device to save power"

My main link is 851 Mbs down and 40 Mbs up.

My DMAF5 gets 248 Mbs down and 40 Mbs up. Wifi 5 links are UAP-AC-Pro.

Seems solid and adequate to me.
