VERY poor wifi signal on Universal

Hi,
I am new to Universal (but not to HTC units ), so when I got a used one with a broken LCD last week I was very excited. But after I replaced the display and played around a bit with this toy - I thought it was not worth the hype.
But I got more & more suspicious about its wifi antenna and yes it definitely has some problem. It has 50% of the signal strength a half meter from my wifi router. From three meters it drops to 25%. And after 5 meters it's dead.
I upgraded the Radio stack to 1.14.10, but nothing's changed. Has anybody any suggestion?
The unit was taken apart by the previous owner and it is missing some screws - but all the screws around the antenna is in place...
If somebody needs photos I can post some.
Please advise!

Cheers

Have you tried going into wireless lan settings, then click on the power mode tab and change to best performance. That should do something. Maybe its set to best battery which would give you crappy performance and range. I am able to log into the internet wifi within my block.

HTC UNIVERSAL wifi power is very very ow i have the same problem and way to solve it. when my laptop says what signal is excelent my ppc cannot connect.

Thank you for your suggestion - now it's in midway position. It should do better - 4 meter is deadly! I have tried out with an Alpine and a Wizard as well and both done a better job!
Can you do me a favour and test it? I measured it at 0.5 m - 1 m and 4 m without _any_ obstruction (no wall whatsoever) between Universal and my router... That is why I suspected a hw failure.
Thanks,
ym

But _that_ low?!?
Very strange however, since both Alpine and Wizard do a better job than my Asus laptop with built in wifi. So this would be a big surprise for me from a HTC unit...
Today I will test it with a Pretec SD wifi card - if this beast let me install the card's driver at the first place

i can use my exec in bed which is 10 meters, one floor and one wall away.
the signal is at about 1/3 strength at that distance which is ok but not as good as my laptop.
have you changed any settings on your wireless base station as this could also be the problem.

Continuing Uni WiFi problem
Sorry to post in an old thread, but there doesn't seem to have been any resolution here. I have the same problem as the OP, in that my Uni will only detect WiFi about two metres from the router unobstructed. Any further, and the Uni loses the signal. My Laptop gets the signal up to 15 metres away, through walls & floors, and my desktop is in another room using the wireless aswell. If it's any use to possible helpers, i'm running KDS WM6, previously standard WM5, and the router is a TP-Link branded thingy.
Any help would be greatly appreciated, it's intensely annoying being unable to use the WiFi functionality on the PDA.
Thanks in advance.

No real help sorry, but my Exec has terrible WiFi performance too. Within a couple of metres of the router it has max signal, but this drops off to 1/2 after 5m. (Laptop still shows full) And anything over 7/8m you may as well forget. Laptop seems to get twice the range. My old HP Ipaq 5xxx series PDA used to get much better perfromance than the exec, but lasted a lot less on WiFi. Maybe HTC have deliberately sacrificed range for battery life? Even with the device set to max performace? I wonder if anyone could do a registry hack to up the power to the WiFi, or would this potentially burn our the device?

Range issue - power of PDA or router?
Thanks for the reply anyway Steve. I reckon my range is even worse than yours - I mean, seriously, I have to be sat right nest to the router to get a signal. As may be apparent, i'm more of a 'consumer' than a developer when it comes to my Exec, but to continue your line of thought, is it an issue with the power coming from the Universal's Wifi, or from the router itself? I imagine if there are very few of us with this problem, then it's down to some poor router setup/cheap hardware on our part...
But yeah, if anyone with a little more knowhow could shed some more light on our problem, i'm sure we would all be very grateful.
Regards

wow i thought i only had this problem, a friend of mine said upgrading might help. any way i've posted a thread about the same problem here

doesnt it kills you not being able to use the wi-fi in such a device???????

I would bet the Universal, as I've always had the same router, in the same place with every wireless device I've used. The Uni is the worst performing of the bunch by a noticable margin.
Then again, I wonder if it has something to do with where the WiFi antenna is in the Uni itself? If the phone is pointing the wrong way the the phone itself blocks the signal? Every other device I have used has an external antenna (even the Ipaq)...
Hmm help needed from some experts here me thinks!

Expert Help needed, I agree
I doubt it's anything to do with the orientation of the antenna in the device, my lappy has an internal antenna and gets the signal just fine. Also, to add to the list of 'working' wireless devices, even my Nintendo DS picks up the signal throughout the house... Does radio version have anything to do with Wifi reception? I'm using 1.10 - y'reckon I should try 1.18 see if that helps? Rhetorical question, sorry - I'll TRY 1.18 and let you know if it helps.

not only poor wifi signal, the gsm signal also poor at uni, any solution of the gsm signal become stronger??

Aside from the fact that I cannot read Polish, if I am not mistaken, that external antenna connector is already present in the BA. Look behind the BA (where the camera is), and you may have a rubber piece covering it, but it does have a connector for an external antenna...
BTW, I am too lazy to go to translate.google.com, what is that thing attached to the Axim?

i believe the connector on the back is only for external gsm/gprs antennae (is that the plural?). my universal has 2 external antenna connectors. one is for gsm/gprs, one is for umts. i guess those conectors are frequency dependant, so i guess the wi-fi signal could not be enhanced with that. but since something like that has never been requested before, we are just guessing here.

We don't guess Chef, we make educated remarks of doubtful validity

i think ur right chef tony..but do you know where is the internal wifi antenna inside the BA?
or what its look like?

in my signature the last link points to the htc blueangel service manual. you can look up any given hardware part there. especially towards the end of it, there is a list of spare parts with pictures.

Required: HTC One X PCB Layout

hello,
While solving the wifi issue, accidentally wifi pin(spring) from motherboard got broken and now i m not able to do soldering and my wifi is not working.
I need PCB Layout (or motherboard layout or main board layout or circuit diagram) for HTC One X so that i can trace the connection for wifi and directly connect there if possible.
I tried to search on google but cudnt find it. can someone plz provide the layout??
I dont know why its not easily available on internet. do companies hide this kind of info?
bcoz my phone is imported from another country, HTC service center refused to repair it...
plz help me..
thank you.

broken antenna is shown in the pic.
plz tell me if i can solve this issue somehow. i have attached the pic which shows the broken part.

Your cellphone is a Quadcore..and I took my tester and betwen the 2 pins there are 1.2 omhs so is the same point of the PBC..in the backdoor both pins touch the same plate..maybe you only need is try to separate a little the pin to be sure it touches the plate in the backdoor
I hope this help..sorry bad english

Thanks for replying ...! Finally some1 replied...
Slight confusion here..
Plz tell me what shud I do exactly? Shud I use the other pin instead of that broken pin? Bcoz they r the same..?

I think that is the same You should start by cleaning the plate in the backdoor and pull gently the pin .and assambly again.hope it helps

it is the same point, juste solder a wire between the remaining good point and the antena in the housing, be careful not to breack the only one point left.
if you don't want to use soldering any more, juste gently pull the pin to make it touch the antena, remember you have to do it gentely !!!!

its working now..!

thanks for helping..! i took the help of an expert for soldering purpose and its done..!! now wifi is working nicely.. :good:
but i feel that its fluctuating many times. means at the same place suddenly there will be more signal strength and suddenly it will decrease also..!! (i think thats not something to worry bcoz it happens at the places which are lil far from router.)

happy to hear it worked, you did the best solution, asking help of expert in soldering :good:
don't worry about the fluctuating of wifi since you are far from the router, this is normal.

[Q] Service Bars

Yesterday I replaced ad USB board (as an old one become faulty and I have had problems with charging the phone). I can confirm I used the appropriate board model.
Today I noticed that my service bars are not as good as they used to be. Generally in the room I usually used to talk and have weak 1 bar service, right now I have no service. I tested my phone outside as well and have a feeling like the phone has no as good perception as it used to have. Another words the service bars wen down everywhere about 20% or so. Phone works fine and I see no other problems. I wonder is there might be something that affects the service bars hardware-wise ? Any ideas appreciated.

The antenna. I think we have 2, one for GSM and one for LTE.
Google for a picture with exact location and try to re-tighten them.
That's all I can think of.

Thanks for suggestions. Yes the one for GPS works fine as I have no problem with GPS (that is the one on a foil. The one for connecting to the tower is a straight wire. This wire goes from the little board (with USB port I've replaced) to the MB. I reopened the phone today and removed the antenna cable. Tested for continuity - OK, cleaned the connectors but still not luck.
I wonder if this could be some compatybility issue or deffective USB board. The board shows T889 rev1.0 so it sound like it's one of the first ones. Unfortunately I made a big mistake (to late) and thrown away old board. It had a problem with the USB post but there was no problem with the signal strength. I wonder if it is common for the usb board to go bad or if there is anything else I could possibly check. I ordered new antenna cable and thinking about getting another USB board, but if this will not fix the problem I'm clueless. I also restored the phone to factory settings to make sure it is not software problem. I need to use this phone daily at work and I'm really pissed off with the problems. PLEASE HELP
Thank you - ARTHUR

Just a question, ,, have you tried flashing the modem? Not sure it would help but maybe rewriting the radio files will help you.
Good luck

[solution] lg g3 gps not working at any rom - pokemon go

Hey, everyone!
I discovered that my GPS wasn't working when I tried to play Pokémon GO. Since then I was trying to find a solution to this, but no one knew. Then I followed this tutorial:
I know it's in spanish, but the process is very simple. It's explained here: http://forum.xda-developers.com/showpost.php?p=58405832&postcount=8
Before the GPS didn't lock, and now I use GPS Locker and can play the game flawless with GPS locked at 9-10/20.
Hope it can solve your problem too!

Thanks for sharing your experience! I have experimented a lot with D855 GPS (different home made "random" antennas, etc) and for me as well the best solution turned out to simply restore electrical connectivity between mainboard and stock GPS antenna (which, by the way, is diversity antenna for LTE B7 band as well). Probably soon I will make a post with more details on this topic.

Hello DavisNT, i know it's old and all, but could you please elaborate on what you mean by "best solution turned out to simply restore electrical connectivity between mainboard and stock GPS antenna (which, by the way, is diversity antenna for LTE B7 band as well)".
What do you mean by "restore electricla connectivity between mainboard and stock GPS antenna?
Could this be explained by using the D855 servicing manual (https://docs.google.com/uc?id=0ByPDG_y4xLa4Y3RzR256bDExOUk&export=download)?
My G3 is serving me well but I'm almost buying another phone only because my GPS is piss poor compared to other phones in my home (Moto G, Moto E, Zenphone 2, Galaxy Tab 10).
So i would like to save my G3 because it's only issue is the damned GPS.
If you could help me on this i would be very happy
Thanks in advance

I meant just detaching the back panel housing (with GPS antenna), may be cleaning the GPS/B7 div antenna connection with alcohol (I have no idea whether this made any improvements), and putting the phone back together. In my case it helped restoring GPS functionality (with similar or may be a bit better sensitivity then the randm-wire antenna mods I tried).
Anyway - the LG D855 GPS sensitivity is much worse than on many other phones (e.g. Samsung I9300). Besides if Lineage OS (not newest stock ROM) is installed on D855 then it can use only GPS satellites (and no GLONASS satellites) to calculate the location.
