Hi,
yesterday my brand new Photon Q arrived, which - after doing the SIM mod - hopefully will replace my Sony Xperia Pro.
While playing around with the Photon there was some thing that disappointed me a lot:
The sensitivity of WLAN is very poor. I own 6 android devices with WLAN, and the Photon has the poorest WLAN sensitivity of all.
Using it about 10 m away from my router, through a thin wall of bricks, it tells me connection rates of about 2 MBit only (varies from 1 - 5 MBit).
My Xperia Pro shows - at the same place - connection rates from 60 to 65 MBit!
What are your expierences with WLAN on your Photon Q devices - compared to other devices you own?
Thank you.
P.S.: 2 m away from the router the speed is 60-65 MBit too, so maybe I have an issue with the antenna of the photon Q?
Hi.
Although this is pretty old, I feel like answering to it, since there never has been any answer.
What was it, that caused your poor WLAN? I guess, the guys who do the SIM mod, when they cut the small gap the inner cover where you insert the SIM later, they sometimes damage the antenna in that spot, which may be the WLAN antenna. What do you think?
I have a SIM-modded PQ, but no problems with wi-fi.When I disaśembled PQ I haven't seen anything antenna-like (wires, fractal mazes) on the motherboard...
The back piece of the phone that holds the speaker and camera flash also contains the antennas. On the bottom there is a piece of black tape that I'm pretty sure covers one. Maybe this piece was damaged where an antenna is located?

That's correct. It holds all sorts of antennas, and on the back of the battery there must be the NFC antenna, right?
The seller, who modded the phone now told me, that at the bottm, where he made the SIM slot, there is the GSM antenna, not the WLAN one. So, today I'll get to open it and have a look, what else looks disordered. Maybe some plug on the mainboard or some of the antenna contact is bad. And just in case - I have one more cover from another PQ.
But if all this doesn't help - I'm grateful for more ideas
Yes, on the back of battery that's NFC antenna. Dismounting PQ is quite easy, but you have to have a T5 torx screwdriver.
I know how to unscrew the cover and even the mainboard of the PQ and I have precise tools.
Having done so and having replaced the cover with the slightly damaged antenna by another one where everything is intact - I experience the same weak WLAN It says 1 MBit/s in 2m distance or up to 20 MBit/s, when I am 10cm next to the access point. What else can be wrong or damaged?
If the cover is ok, maybe connectors to PCB are dirty/damaged (but you've probably already checked it). And how about another router? Maybe the one you're using is damaged or "doesn't like" PQ?
Thanks for the ideas, but from what I can see, they look good and clean and bent the right way to make safe contact And yes I tries other access points. I tried with my Droid4 providing a hotspot, my tablet, at my family's house, my girlfriend's, at work, at home... It's the same everywhere: very close or up to 3 meters, no obstacles, I have signal, but 1 or 6 MBit/s only, Further away or a door in between it's gone.
Can Android (CM 12.1 / 5.1.1) cause this, or must there be a hardware issue? How likely is it that these kind of problems are caused by a broken WLAN chip rather than an antenna problem?
I bought it in this condition from a guy who modded it (SIM mod)

Flash stock if you'd like to rule out issues with CM - although I doubt it, definitely sounds like a hardware issue.
I returned the phone to the seller, it was definitely something wrong with the hardware. I ordered a fully working board from another seller, since I still had a damaged Photon Q anyway, SIM modded it myselt and got everything working now, incl. GSM and WLAN. Thanks here.
Hi,
I just got my x3 nfc and I was testing it. It is constantly losing the 5g connection to my router and default to the 2.4g.
I checked with Wifi Analyzer and it shows -20mdB more than normal, by normal I mean, I checked on an other phone (sony) and on the same 5g same spot it shows the difference (Sony -60mdB and X3 -80mdB)
Is anyone else experiencing issues on the 5g wifi? in case, anyone knows if it is a software issue on this model or an hardware issue?
Are you on a custom ROM?
There are multiple reports of poor wifi connectivity around -- apparently, they all lag behind stock ROMs, which aren't themselves perfect on this aspect.

I am still on stock. my big doubt is if this is an hardware flaw of this model or just a software issue that could be fixed in the feature.. I am not sure if the antenna is physically for both 2.4g and 5g or it is separate, as the 2.4g have a good signal, at least at the same level of the other phones. It is just the 5g that is drammatically poor even in front of the router. If I try to use it after a while it fallback to the 2.4g

i have the same issue with my x3 NFC Global... i thinks only my device, im relax now , i think it would be fixed in the next update ( i hope so) because is really really bad on 5g wifi, did you can fix it manually? im searching some info
sorry for my bad english, saludos desde México
Hello!
My display from my Mi Note 10 broke a few days ago, so I ordered a replacement screen with the frame.
After I reassembled the phone in the new frame, the display worked fine.
But I noticed that my wifi signal was very weak. I had to be next to my router to get a full signal.
The GPS is also not working.
The mobile data is working normally. Only the wifi and GPS are not working.
I don't think I broke the antenna cable.
I think there is a missing connection/contact between the motherboard and the frame. So it can use the frame as antenna.
If someone could help me to solve this, I would be very grateful!
Thanks!

Have you figured it out or not?
Exactly that same issue.
Kinda interesting that it worked for quite some time after the replacement. But i have an antenna cable to blame, thought. During assembly process i accidentally broke it. I'm not sure whether that is the true reason. I tried to twist my phone, but it didn't work.
Also i tried to swap antenna cable (longer one) from P30Pro, and it didn't once again!
I'm running out of suspects now. I want to know where the GPS antenna is located. Is that a small board at the very top left?
P.S. Almost a year passed
Pls anybody..
I'm going nuts with this thing already. I checked everything i could : i used another antenna cable (white colored) i cleaned all the contacts i removed that small antenna at the top and nothing changed at all. I'm starting to get nervous because it might actually end up digging a half of the mobo...
Hi everyone! I have a problem with my Poco x3 Pro and I wanted to see if the same thing happened to someone, or ask for advice to find out where the problem comes from.
I bought a Poco x3 Pro 6 / 128gb 3 months ago, and last month, the wifi began to lose the internet signal since it is still connected to the wifi network but it is as if the signal was cut off, and it is enough to turn off and quickly turn the wifi back on on the phone to regain the signal.
It seems like something that can be quickly corrected, but when I'm playing online, it is quite annoying since suddenly without apparent cause, the Internet is cut off (with Wi-Fi and the network connected).
As additional data, it came with MIUI version 12.0.6 and although I updated to 12.5.2 (I also did a factory reset) the problem continued to occur.
Has anyone happened to you or advise me how can I find out the source of the problem? Since it could be my wifi (I really do not think so, I have a Redmi Note 9 Pro, Redmi Note 8 and Redmi Note 6 Pro and this does not happen, the signal is quite stable) or the same phone.
Thank you and sorry for my english haha
Firstly, 'forget' the WiFi connection on the phone and then turn off your router for a couple of minutes. Boot the router back up and once it's settled down re-connect your phone.
You don't say how often or quickly this occurs but if it does still happen then can you test elsewhere? Either a public WiFi connection or a friends or family members home maybe?
I get similar problem, usually after a night. Phone shows WiFi active, but no Internet connection and no ping to any local device. Other phones have no problems with the same WiFi network. It is enough to turn off WiFi on phone for a moment to get it working again.
My POCO is V12.5.1.0.RJUEUXM.
i have the same problem with my poco x3 pro 8/256, but only with wifi sign 5GHz, with 2G it working nomaly. i use Asus wireless Router RT-AX 55. i think it's isusse update new version, when i update 12.5.2 stable Offical
Since i inserted the SIM card, the problem seems to have stopped, but I don't see a direct relationship.. I will evaluate these weeks.
Maybe it switches to LTE? I have SIM inserted but disabled data and still notice problems.

Did these problems come to you from the beginning?
Yes for me. I didn't use this phone much, while waiting for bootloader unlock. It updated itself to MIUI V12.5.1.0.RJUEUXM at first boot and since then I observed WiFi loosing connection after nearly each night. But I noticed no breaks, while actively using the phone.

It is strange, in my case it will be necessary to test it with another WiFi..
PD: I update, it keeps happening to me, I will only use 4G to play games ..
I switched to ArrowOS and noticed one instance of WiFi failure. Then I disabled random MAC on phone and it seems to work OK now, but is to early to draw any conclusion. I don't remember if random MAC was active in MIUI.
While rare, problem still exist. Effect is that WiFi connection is broken an system cant find AP. But WiFiAnalyzer work OK and shows available AP. Turning WiFi off and on restores connection.
I have disabled protocol 802.11r on my network and for some days I have no more WiFi failures.

Okey bro, let me know if you have the problem again please, thanks.
I believe my problem is solved or rather circumvented and WiFi works OK. I'm using routers with openwrt. Maybe it doesn't cooperate well with Xiaomi.
Have the same problem, unmark "IPV6" and "QoS" in the router settings and problem solved.

Don't connect to 5G wifi on your router, , , Poco X3 pro 4G only that's why you disconnect.

5Ghz works perfectly for me. I presume you mean 2.4Ghz, not 4G?
Edit: or did I miss a 'joke'?

As described by Qualcomm's website the Snapdragon 860 supports 5G and WiFi 6 connections, but the Poco X3 Pro doesn't. Try to switch 2.4G

You've lost me, I connect via 5Ghz and don't have any issues, why would I drop to 2.4Ghz?

I think you are right, I separated the 2.4 and 5 GHz connections inside the router and I connect with the Poco x3 Pro only to the 2.4 and it has been perfect so far.
I will update the thread if there are problems.
Thx.
Hi, guys. Recently I acquired a rog phone 5s, but since I started to use it, I'm facing problems with my connection. Basically what's been going on is that sometimes my wifi starts to disconnect and connect on my phone.
This problem already happened with my father's phone (a realme gt master), but apparently stoped after some months; it happened with my old Poco X3 NFC when I rooted it too. These 2 occurrences make me distrust that the problem is in the wifi network or modem itself.
Some usefull informations:
- Here in Brazil we have some local internet providers that offers optical fiber connection, as the big companies here doesn't offers it in smaller cities. My internet provider is one of those smallers providers.
- I have 2 internet bands, one in 5ghz and another in 2.4ghz. When I had this same problem with my Poco X3, someone here said me that the the reason for the problem is an interference between these 2 channels.
- I never tried to fix this problem changing the networks configs directly on modem or call someone to fix it cause my parents insist that the problem is in the cell phone
Overall, that's it. I'm available to answer any questions in case anyone hasn't understood something, and sorry for my bad english, idk the grammatical rules of that language
That happened to me until the wifi completely went out and never turned back on. It's a motherboard issue I sent it to Asus to get repaired twice

are you sure that the problem is really on the rog phone? my father's phone had this same problem and it returned to work normally after some months
