[PX3] Wifi stopped working - no connection - MTCD Android Head Units Q&A

Hi,
i own a Xtrons PX3 with Android 7.1.2.
A couple months ago i noticed connection failures on my wifi. Over the following weeks the problem got worse. Today the device is completly unable to even find access points. Bluetooth is working perfectly.
I tried the following steps:
- multiple switching off and on again of wife: "activating wifi" taked about a minute. No access points. Wifi disables itself and turns on without finding networks.
- activating the access point: no effect
- replaced the antenna: no effect
- reseted network settings:
The wifi worked for one time 3 minutes. I was able to connect to my mobile phones access point. But after about 3 minutes the same error again. No networks. No connection at all.
- upgraded the MCU from MTCD_GS_V2.56_3 to MTCD_GS_2.94: no effect
- installed Malaysk 5.0 from https://forum.xda-developers.com/an...nt/rom-malaysk-roms-mtcd-mtce-device-t3693509 without data wipe: no effect
- installed Malaysk 5.0 WITH complete data wipe:
Again the wifi worked one time for 3 minutes. But now no wifi whatsoever.
I dont think it is a hardware issue. Otherwise it shouldnt have worked for some minuted after the complete data wipe.
Please help me. The Head Unit is more or less worthless without an internet connection.
Kind Regards

Hi there. I can assure you that it’s a hardware issue. I had this before and I replaced the WiFi and Bluetooth board and all was good after that.
The symptoms are exactly the same. Works for a moment but not always and for a very short time. This can happen because the chip gets quite hot and the soldering or the chip itself gets damaged.
My advice is to get a compatible board from China, they are very cheap - 2-3$ and replace it. I’ve done this twice now and both Bluetooth and WiFi are working well. I know how it behaves before failing.

Well, thanks. I thought if Bluetooth is working then it should Not be a Hardware issue. Because both things are handeled by the same Module.
Do you have a link or something for me where I can buy such a replacement part? I tried Google and eBay. No success.
Thx.
Kind regards
Hagen

Try AliExpress. I don’t know what kind of chip you have now to be able to advise.
The Bluetooth and WiFi can be on the same chip but the connections are different pins.
It might be a good idea before ordering and waiting to try and repeat the soldering points to the board.

Abbysmal GPS and WiFi Signal

I have looked far and wide for a fix to my plagued Nexus S GPS and WiFi Signal problems. I tried GPS Test and erased all cached AGPS data. NO Towers show up. Left phone sitting there next to my window for more than 30 minutes.
Wifi Signal is always one bar while my iPod, Samsung Focus, HP Veer all get three to four bars. Including different SIM cards all recently new.
I've always tried the no battery cover trick to no end. Flashed several radios for my I9020A that i bought at best buy and nothing has helped.
I'm on 2.3.4.
Any ideas before I return this phone as a defective and give another a try?
As for the GPS, this is some sort of issue with the phone. There have been videos on YouTube explaining that it's something to do with the back cover they chose: they found that the GPS signal was stronger with the back cover removed. Not too practical.
I too have issues while using Navigation (on a bus...or even in a car sometimes...it must have a lead lines roof or something) with the Nexus S that weren't present in the Nexus One (which could lock onto satellites in a basement :what. This looks like something you can try to DRM, but it may not improve.
As for the Wifi signal, how far are you from the access point? What wireless technology are you setting up on your access point? (802.11a, b, g, or n?). If it's n? Are you trying to use the phone with a 5ghz N router? Finally, is there anything between your router and the phone that could cause interference?

Thanks for the reply chris.
I have major issues even outside. the most accurate I've seen the phone pinpoint is 2500 meters accuracy with clear skies and such.
As for my router, its a BHN SBG6580. Basically Motorola Surf Board. It's supposed to go up to N. No There isn't any kind of interference otherwise my other devices wouldn't pick up a good signal right?
Please will anyone suggest anything I really like my nexus s and it's My first real Android coming from window phones and the iPhone 4
Okay so interesting find. If I tether my nexus s to my iPod my iPod can locate itself within 20 meters where as my nexus can't locate itself with about a huge margin error where I should be. My iPod gets GPS from my Nexus S giving off wifi
Does this mean it could be an android bug causing his problem ?
That's odd. It looks like Google knows where the phone is (err..where the access point with the ESSID of your phone is) but the phone isn't picking up on it.
There's a program on market called GPS Toolkit (something like that) that has an option to refresh your AGPS cache this may help you get a fix more quickly. If this doesn't work out, it may well be worth it to get the phone replaced. Oh...and if you're not using stock firmware....give that a try as well.
If none of that works, and you're not able to resolve your wireless issues, you may want to consider taking the phone back or RMAing it. This combination of issues sounds a bit strange.

Thanks again for the reply Chris.
It looks like I'm going to bring it back to stock how I got it and return it for an exchange or just wait or for another AT&T phone that is actually decent. By the way it is on the stock ROM just rooted.
If the replacement if I do get one issued still has the problems I am at lost then. I had tried GPS test from the market and the one you mentioned without any resolve to my problem

Nexus 5 won't connect to wifi

Hi guys. Recently I purchased a used nexus 5 off of eBay, and I am having some trouble getting it to connect to my WiFi. When I received the phone, wifi was working. it was on 4.4. I unlocked the bootloader, and installed twrp, but did not root it yet. I did OTAs up to 6.0.1, and then I started having issues. Upon turning on WiFi, the phone would just say "turning on WiFi", and never show me any networks. I thought this might be a kernel problem so I tried many different ones, but no luck. I used the nexus factory image to downgrade to 4.4 because the WiFi was working then, but still no luck. It will very rarely connect, but it will loose connection after a few seconds, and continue searching. I looked in the settings and realized that my MAC address showed " unavalible", so I used this guide to change it.
http://forum.xda-developers.com/goo...icked-nexus-5-externel-storage-t2740471/page5
Now the Mac address shows up in settings, but I still can't get it to connect to WiFi networks for more than a few seconds if the WiFi even turns on.
Any help would be gladly appreciated! Thanks.
I had the same problem with two nexus 5 phones. The WiFi chip seems to have failed on both. After changing the motherboard in both phones, WiFi was working without issues. The only thing I changed in both phones was the motherboard.
Before changing the motherboards, I could never get WiFi to work with all combinations of roms, kernels, and boot images.
If you satisfy the following:
- the phone doesn't connect to any WiFi network on full stock unmodified software
- other devices connect to the same WiFi networks without issue (sanity check )
Then almost certainly a hardware issue with the phone. No amount of modding or flashing is likely to change this.
Ok, thanks
Have any suggestions on where to buy a motherboard? Don't really want to spend a hundred bucks.
I purchased a couple of nexus 5 phones with smashed screens for a low price and swapped out the motherboards.

wifi in Nexus 5 not working - marshmallow

My wifi is stuck on "turning on" after getting reset multiple times automatically. I have the logs. How to attach ?
Does wifi work with any other ROMs?
I have the same problem... And now i played with my device and figured out that my mac address is 02:00:00:00:00:00... And after a while it is normal... What about that, is it possible that wifi antenna is faulty, not the chip...or motherboard... Because everything works normal...
If the phone has never been dropped or bumped, it's unlikely there would be a problem with the wifi antenna but it is possible that so,etching came loose over time.
I suggest trying a couple of other ROMs to see if wifi works. If it still doesn't work, dismantle the phone and look for loose connections. If everything appears fine, i would conclude that the wifi chip is defective.

Major wifi issue in pixel

Everything is smooth and perfect except Wifi.
I can found close wifi networks (Mobile hotspots created by other phones) but if I try to connect it just saves them, cannot connect to any wifi networks.
And the strength is too low. It is unable to find my room's wifi ...!!
So I am just totally unable to use wifi in my Pixel :/
Also I turn on Hotspot on my Pixel, it turns on but I cannot find it from other devices.
Also upgraded from 8.1.0 to 9.0 but still same issue.
Without Wifi its so miserable experience Any Solution?????
Yeah, same issue. It's a hardware thing. If you've dropped your phone either the cable came loose or the PCB board is off. I threw mine before (long story) but can't use wifi nor Bluetooth without being close to what I'm connected to.
I just don't feel like fixing it considering the pixel can break by repair. Plus, my 6p is my DD anyway
Dang, I gave my sister this phone and this problem just appeared. Time to look for a new phone for her.
Ok, being real for a second, this worked and I know it is a VERY BAD workaround but can help in a pinch.
I bought a refurb pixel on woot. Took a while to get it because it was sent to a friend's PO box and then brought to mexico, ergo no warranty.
Unboxed it and had this exact same issue; little to no signal on very few wifi hotspots and just "saving"
Seeing as this might be hardware related as @creep138 mentioned, I tried the following:
PRESS considerably hard on the point that the antenna connector should be.
After a couple of seconds of force and massaging, wifi came on and connected.
I KNOW this is a bad idea, I KNOW this might cause several issues on the long run, but if you have it sitting in a drawer doing nothing because of this issue, give it a try.
For reference this was done on a Verizon Black Pixel. The small one. and the point to apply pressure to is about half an inch below the camera and flash module.
Hope this helps

Status update:
After doing what I have already described, that helped to connect to the wifi at my workplace. Nonetheless I didn't have suck luck with my home wifi.
After reading here and there, some users reported the device connecting to 5Ghz wifi no problem. My work is indeed 5Ghz and my home is 2.4
After unpacking and installing a 5Ghz capable router, the pixel connected no problem to it (after applying the aforementioned pressure)
Hope this helps

S10e WiFi connectivity issue

Hello all!
I have a S10e, running stock Android 10. The wifi at my house constantly disconnects and reconnects, rendering my phone as virtually useless, as it switches between my mobile network and wifi. I have tried all of the trouble shooting I've found online, just short of a full backup/master reset. I'm trying to avoid that.
Does anyone have any idea what may be causing this? Better yet, how can I fix it? I'm rather annoyed, as I've had several Samsung Galaxy phones that have had minor issues, but nothing as annoying as this. I'm about to buy another model phone.
Thanks in advance

Hi, I have the S10e G970F_MMI - Singapore Snapdragon. Similar issues with wifi and bluetooth turning off immediately after update. Got one message from Wi-Fi control history that said Google Play services turned off wi-fi. I tried disconnecting Play services but that did not help however I am suspicious that it might also have something to do with Bixby Routines. Tried Samsung but no help as my phone is only 13 months old and 1 month out of warranty and I am not in Singapore but stuck in UK. Like you, I am a long time Samsung client with phones, tablets and TV's but I have now lost confidence in them. I tried factory reset and reflashing the custom ROM but no luck. I do hope that you can resolve your wi-fi issue and have a wonderful New Year.
Apparently, Samsung admitted the S10 series suffers from this issue. I noticed it on mine, just in the last month or two, disconnecting intermittently roughly every 30 minutes. I thought it might have been my router, but I realized it's definitely my phone (S10e US snapdragon).
Nothing I tried fixed it. I did disable "wi-fi power saving mode" and wifi auto connect (I have tasker auto re-connect wifi when it disconnects).
I do have "wi-fi san throttling" enabled in developer options, which shouldn't have anything to do with this. HOWEVER, you might try "wi-fi safe mode" under developer options and see if that helps keep it more persistent.
One other suggestion, though it shouldn't matter, is to try assigning a specific IP address to your phone (do this from your router settings, not your phone). And you can search for other solutions online to cut down on radio interference on your home network. Other devices and neighbors might be disrupting the router signal strength, possibly dropping it below a level that causes your phone to drop wifi.
I got the same problem before, used an Asus router. I changed to a Qualcomm chip router and its fixed. Try a different router?

Unfortunately I cannot, as the router I have is from my internet provider. I would have to run that to another router and at that point it's just a waste of money. Thank you for the info though! If I get annoyed enough I may buy a cheap router to see if it fixes the problem.
