Hi - I recently updated my OP10Pro 5G to the NE2215_11_C26 update, OOS13, US,, and my 5ghz wifi is now really slow - 40-50mbps down - unless I toggle wifi or airplane mode. Speed goes back up to normal, then goes down and stays there. Other devices in 802.11ac work just fine on the 5ghz band

Any idea what's going on?

Thanks

I had exactly the same problem and went through a "chat session" with OnePlus support about two weeks ago. I was asked to send my phone in for "repairs". The way their agent responded to my issue suggested that it is a common problem.

Edit: Sorry, my phone was running OOS 12 at the time I experienced the problem. I don't recall the build number and I don't have the phone now, so I can't check.

So, my phone has been "under repair" now for two weeks. No status update, no idea when it might be repaired or replaced. Meanwhile, I'm using my previous phone, a Moto One Ace 5G, and wondering why I bought the OnePlus at all.

Did you check the negotiate speed?
Have a look with WiFi Monitor, ight shed some light.

I think I figured out my problem. I have Verizon FiOS, and have a G1000 Quantum Gateway AC router and the matching extender. The extender had the same SSID for the 5ghz band as the main router .. so the phone would hang on to the router or extender no matter where I moved in the house, no matter whether I checked the "switch Wifi to stronger network" box. I created a 'sub' SSID, and now the phone will (usually) switch to the stronger network, and seems to work ok.
I didn't have this with my AC Wifi OnePlus 7 Pro, or with my AX laptop. But this did seem to fix the issue with the OP10. I wonder if the new FiOS wifi 6e router + new extender would work better with my 10 Pro if extender is broadcasting same SSID?

As long as the 2.4GHz and 5GHz bands will share the same SSID that's l;ikely the phone will pick the one with the "strongest signal".
If you want to make sure to always connect to the 5GHz one, using a different SSID is the only option. Doesn't really matter which AP/router/repeater/extender you use.

Yea.. the issue was that I had the 5ghz band on the SAME SSID being broadcast by both router and extender.. forgetting the 2.4ghz didn't do anything, nor did ensuring that the "switch to stronger Wifi network" toggle was on. My OP10Pro would connect to the router's 5ghz signal when entering the house, then stay on it when moving around the house without switching to the stronger 5ghz signal with same SSID emitted by the extender. By creating TWO 5ghz SSIDs, one for router and one for extender, the OP10Pro now - usually, it isn't perfect - switches between the router/extender 5ghz SSIDs depending on the signal strength, though Android13's cutoff for defining "weak signal" seems either arbitrary or very forgiving. I'm wondering if Verizon's new Wifi 6E router + extender will fix this issue and allow me to just clone the SSID on both devices.. i read somewhere that wifi 6 and 6e devices can do this natively.. not sure as I'm a novice at best at networking. Thanks.

Other than the actual "sensibility", that's not a 10pro specific issue.
2.4 and 5 GHz bands will behave differently and the phone will "perceive" one or the other as the best choice based on various factors and the overall quality of the signal.
I had the very same issue on my laptop. :)

OnePlus support had my phone for 3 weeks to fix my 5G wifi speed problem. They report that they replaced the motherboard under warranty and the phone has been shipped back to me. I should have it in a couple days and will certainly test to confirm that 5G wifi speed is similar to other devices connected to my network.

I've defined separate SSIDs for 2.4g and 5g wifi in my gateway, so I can control which SSID I connect to. 2.4g was always consistent with other devices connected at 2.4g. The problem with my phone was related only to 5g.

I received my "fixed" phone about a week ago now and I've been monitoring its wifi performance. Bottom line: 5G has been generally slow, much slower than my laptop or my Moto Ace 5G, but the speed is highly variable and quite fast sometimes. I just ran Speedtest on my laptop and OnePlus. Both were connected to the same 5G SSID. The laptop performance was 304 mbps down, 172 mbps up. The OnePlus performance was 48 mbps down, 205 mbps up.

I switched both the phone and the laptop to my 2.4G SSID. Laptop performance was 43 mbps down and 15 up. Phone performance was 116 mbps down and 88 mbps up.

After the 2.4G test, I switched the phone and the laptop back to the 5G SSID and immediately retested wifi speed. I observed performance of 339 mbps down and 373 mbps up on the phone. The laptop speed was 248 mbps down and 148 mbps up.

I know that my gateway broadcasts 5G on two different channels for the same SSID and I have no control over what channels it picks. Maybe the phone picks a congested channel sometimes and the slow observed speeds are due to that, whereas the laptop (and the Moto Ace) always seem to pick the less congested channel?

The other thing I read about was "randomized MAC address" versus "device MAC address" and someone, somewhere (I don't remember where) suggested that using device MAC address resulted in improved speed. I just made that switch for the 5G SSID. Speed is very good now, and I'll monitor it to see if it slows over time.

Sorry for the long message, but I'm thinking that the "fix" really did nothing to improve 5G wifi performance and there is something not quite right about the OnePlus's handling of 5G wifi.
