poor Wi-Fi reception signal - HD2 Windows Mobile 6.5 Q&A, Help & Troubleshooting

purchased 2 of those devices specifically to use for tethering, need a device with wm6.5 and unfortunately can't use it since it can't pick up any signal from my routers or iphone or bluetooth tethering.
i can have this thing sitting on top of wifi ap and still get no signal. does anyone have any sort of a fix for it? thanks !
tried updating to RUU_Leo_1_5_TMOUS_3.14.531.1_Radio_15.42.50.11U_2.15.50.14_LEO_1.5_Ship but it error out
my rom is 3.14.405.2

Would assume they have been opened for repair & not assembled correctly.
Usual issue for wifi/BT is coax cable not clipped into brass connectors correctly.
ideally you need pull back cover off & check the cables that rundown side near volume button.
also check all spring fingers on mainboard that contact on arial tabs of rear housing are present & correct position to contact.
Many people snap the spring fingers off the mainboard with rough handling & don't clip the coax cables in properly.
Also worth noting you have a power setting for wifi so that needs setting to max to help maximise range.
Use over 20 HD'2 in my work enviroment & wifi is perfectly good enough & they make a great wifi router/tetherer with wmwifirouter

thanks !
to pull back cover i need to use heatgun? i used setting for max power w/o any result

To remove rear cover you don't use heatgun.
Pull battery, sim & memory card, remove all screws.
Use a plastic pry tool to loosen edges top & sides
*do not push any tools in around volume button area*
Main trick is to start at top as top has 2 good clips either side of speaker grill
once top showing signs of release work round side without volume key & once this shows signs of coming off it very easy.
Do not use metal tools, screwdriver as cause horrendous damage
Take care as many things are easily broken with poor handling.
Cover clips back very easily.

External antenna for wifi ?

Anyone know of a possability to have an external antenna for wifi or anything else that would help increase or focus the signal to get a better/further wireless connection ?
Any ideas are welcome even if it means working (soldering) on the actual board of the Tytn if anyone has done something similar please post your findings here.
Tytn has an external antenna connector under a little cover on the case. Wilson sells antennas and cables and such for it, plug and play.
http://www.wpsantennas.com/
Thanks for the reply Bro, but will this boost the wifi module or just the phone signal ?
Just the phone signal as far as I've read. I'm not sure though.
I'll be trying it out as soon as mine gets here and I can let ya know, I need one for trying to get reception in the rural areas I go to often.
I have read somewhere on this forum that using the atennas that plug into the port on the back are a bad idea in these phones cuz the soders on the board break easily if you do and you lose all phone signal. I couldnt find again where I read it, sorry. So be careful if you do it.
Thanks for the heads up bro, I don't mind the phone signal (aside from tunnels) but I do want to boost the wifi, I guess we're stuck with this till a better phone comes out
im sure you could maybe, make some freak monster connector for the wifi antennas? nobody has done that? isnt there some basic internal one? or how does the wifi signal get broadcast/received?
yeah its possible but I don't want to fry the board if I put something that draws more power than the board can handle (because it sends and recieves) so I wanted to see if some electric engineer or hobbyist has ventured something like this before
your better off with some wrt54g(s) with ddwrt on it and use it to connect to it and then use the wrt54 to connect to whatever it is that you want for range lol i dont know in what situation your in... if its portable then ya the router thing would not work well if in car? or some other place then that would be the best choice heh
but if your connecting external antenna then its not really that portable anymore is it
Sounds interesting... thanks for the info I look into that,
I have no problem at home or at Uni but in hotels I usually have to point the device around to catch a signal (heads up that's where the base for wifi is) and the signal is so weak it disconnects or gets real slow somewhat annoying, still better than carrying a laptop around on small trips.
i'm willing to open mine up for better wifi, i would just like a guide or atleast some pictures and pointers with do's and don'ts.
i don't NEED my hermes, but i do love it enough to want it to continue to operate.. heh.
I took mine apart already i wanted to put the bestskinever on the screen its self so while doing that i was going to check out the insides and it was a pain to get it on without any lint and stuff on still got a very small one but its nice i cut the exact size of the whole LCD not the screen dimensions
so it covers it all... anyway
i saw both BT and WIFI internal antennas there... I really did not see any connector... though something that looked like one but i didnt pay much attention it was very small maybe .200" or so
I would assume you could un solder the internal wifi antenna but i would not recommend that... as there are i believe other resistor/capacitor and hmm coil that work for the right antenna length and so on... I THINK I havent done any electronics in a long time and never bothered with such devices and or high frequencies so I would not know.
I would recommend finding some other online forums dealing with the 2.4ghz wifi stuff and learn or ask questions if its possible to make a connector for the phone.
This would be indeed a great DIY project to add to the archives
once again i would recommend that you get a cheap wrt54 put dd-wrt on it... config it properly for it to connect to other devices, they even have scripts to have it connect to open connections and the ones with strongest signal or you could config it manually through the web gui
that is far better IMO then modding your hermes heh, as i would think you would need an amplifier not just external antenna as that only might increase your sensitivity or a little better quality in signal but to boost the transmit power you would need an amplifier
http://dd-wrt.com
there you go find the right one with the right version that will work with dd-wrt they only run like 50 bucks or so… and plus you can use it for anything else… you can boost the transmit power on them as well as replace the generic antennas

[Q] Microphone Hardware Tech Question

I fix all kinds of smartphones for a living. I convinced my buddy to get an LTEvo but his microphone is not working properly. I figured I could just open it up and replace the microphone with a new one. However, I am not sure as to where exactly it is located. I noticed the mic hole on the bottom of the phone and I assume the mic is located on the large flex cable that extends downward toward the bottom of the phone. Would this be accurate? I have included a link to a parts vendor in order to verify that this is indeed the correct part that I need in order to fix his issue.
Large Flex Cable - http://www.globaldirectparts.com/HTC-EVO-4G-LTE-Flex-Cable-Ribbon-p/htc748935.htm#
Close-up of what appears to be the microphone on the ribbon cable - http://www.globaldirectparts.com/PhotoDetails.asp?ShowDesc=N&PhotoNumber=5&ProductCode=HTC748935
While I can't help you completely, there are two mics. One on the top, one on the bottom. I installed a new screen so I disassembled the phone a few times getting everything working correctly. I don't remember if the mic was on the flex cable or if it was part of the boards located on the top and bottom of the phone.
Good luck though.
Edit: found my old screen. I think you're good with those flex cables. Just make sure you get them for both the top and bottom mics.

Bad radio reception

Hello i have a eonon car stereo running android 444 fuse rom i can only pick up 3 stations and they sometimes loose reception ive tried an amplifier and new eariel but with no luck any suggestions would be great.
I'd double check your harness connector to the oem antenna. Their was a pin loose on mine and once I bent the retention tabs back out and reinstalled the connection was much stronger.

Its a Renault Megane and is just a standard connector.
Im now beginning to think its the components on the motherboard as the closer i get to the sauce eg: im from Wigan were Wish FM is broadcast if i drive past the studio its crystal clear same with Key 103 in Manchester. I think the radio chip on these is crap.
I think you need a power injector, because the antenna is active and needs power to work correctly. Just put the power injector between the radio and the antenna and connect the blue cable with the AMP or ANT cable of the radio harness...
Gesendet von meinem D6503 mit Tapatalk
I've had the same issue and solved it fortunately.
My Unit is a Joying RK3188 and came with a defect dual input power injector.
Easy steps to identify: At the output of these injectors (called 'phantomspeisung' in german) you sould measue 12V DC. These 12VDC sent over the 2pol antenna cable are for the antenna built in amplifier.
1st: I replaced the power injector with a diversity injector. Google for "Diversity Adapter 204.086-0) www.rta-online.com
2nd: Additionally to my amplified roof antenna I bought a second amplified antenna at amazon
http://www.amazon.de/Baseline-Conne...enne+AM,FM,+inkl.+Verstärker,+FAKRA-Stecker+F
Both together I've a really good reception now.
The diversity adapater really makes it's job. I is a littel high in price but worth at all.
Try putting some electrical tape around the Motorola male antenna plug at the head unit. What you are trying to accomplish is to insulate the area where the head unit housing may be in close contact with the plug. Takes a few seconds to try.

...that's excatly what provided the very worst reception ever to me... So I looked around (tried a lot and spend some bucks on some useless amplifiers) and finally found the solution from my previous post. It works.

If putting insulating tape just around the plug where it would touch the housing (and not where the actual plug needs to mate up) gave you worse reception... you did something wrong.
I was under the impression that these units had issues with the software ( or hardware) or this is what I am told.
See here or am I mistaken?

Its possible you are mistaken. The OP in this thread didn't provide any hardware specific details. Instead we know only version of android.
My units have no problem with radio reception, but I can simulate a problem if the connector touching the housing and impacting reception.
Other issues are not connecting the power to a stock antenna from the head unit when you install it. Even if you don't have an antenna that goes up and down you can have an amplified antenna. If you don't power it you don't get good reception. it can be something that is missed with wiring up the harness.
Yes, you can also have hardware problems, but its easy to rule out the external issues first before calling the unit the problem.

When you quote "my units have no problem," what software and hardware do you have in each, which motherboard, radio chip, etc etc
I part of me would like to believe that insulation is a problem here, but guys on the Russian forums have replaced capacitors to improve reception.

I have Joying units. One of the 10.1" universal units with 3188 and a 7" universal unit with 3188. No idea about the specifics of the chips.
If you have a specific hardware unit that people are complaining about then you may have a problem with that unit from that manufacturer. That's realistic, but try the other tests first before performing surgery.
Problem is most likely a internal problem with the ground of the antenna input. This was the problem with my unit.

This is great. It really helps illustrate how people are interpret things differently.
You have put too much tape on the connector. You have essentially broken the connection by entirely covering the outer connector. It may not be been obvious to you that a motorola antenna connector needs contact on the pointy post and the outer shell.
What you wanted to do I carefully put just a little tape on the plug where is could touch the case of the unit in a circumstance where the alignment of the female connector inside the case attached to the PCB isn't perfectly centered for the case hole. When things are out of alignment there tends to be a connection between between case and the outer shell of the connector. When these things touch it can negatively impact reception.
Hehe... I made this photos this morning with an unused plug just to illustrate. I know that the connection is broken when insulated and also the it's impossible to work this way.
I also read several threads about that "put some tape on it" thing and heard dozens of interpretations.
A picture tells more than some thousand words.
To clarify that to all of us: Please be so kind and make some photos !
Thanks in advance!

So did you do it correctly when you tried it on your unit or are you saying this now to show the mistake and now you understand you need just a little bit of tape like mentioned up thread?

You might have a grounding issue if you are having to do that. I believe another member noticed that the outer part of the antenna socket is internally grounded with a little bit of solder and some foil, he had noticed that the foil had become disconnected meaning the outer part of the socket was no longer properly grounded, insulating the plug like you have done would help in that situation, but it isn't the correct fix, regrounding the socket is.

You may have read up thread.
1) Check the connections like power for the antenna if you have that
2) check the plug to see if its contacting the case. Tape as needed.
3) Open the case and validate the connection to the female socket on the PCB.
4) Check your MCU firmware
5) Try another unit
This whole tape thing has me so confused. The outer shell of the Motorola plug has to touch the casing for earthing doesn't it? Yet you are saying to tape up only the bits that are touching the casing.
Totally confused.
Can someone put up a picture of what is the right way to tape it please.
I would have done exactly the same as markusmuster has in the pics.
Thanks

[Solved][hack][Thor] unresponsive volume buttons

Hi everyone,
NOTE: volume buttons fix I mention below is superseded, see my reply to this post.
In the following post I was unable to enter recovery or fastboot.
[SOLVED][WCIF] patch0.xml etc for bricked HDX 7 thor? Have QDLoader 9008 access
Fortunately a cable and flashing software solved the problem but the underlying problem turned out to be Hardware (at least).
Only after I got a working OS back on this tablet did I determine that the volume buttons didn't work at all.
But I found by stretching the rubberized case off of the right edge of the screen I presumably compressed the audio subsystem hardware connections in just the right way and this got the headphone jack and the volume buttons to start working again.
With the rubberized case pulled away from the edge I had to cut away the headphone jack area so headphone plug will still fit. Please see better solution in my reply below.
See attached image.

Update:
It turns out on another site ("i fix it") that discusses various handheld devices' hardware someone else identified a better solution that doesn't require physically modifying the tablet.
I found that solution during a search after stretching/distorting the case as described in the post above stopped working.
Basically the soft material this tablet is made out of warps easily and applying a stiff back solved the problem for mine. I used a piece of thin laminated wood available local home improvement stores. I taped that on as seen in the pictures. Before taping the board on, I taped a small cable tie to the back of the case to add a little pressure point approximately an inch in from the top and side edges of the case nearest the headphone jack. That area appears to be where the connection lies that's required to keep the headphone jack and volume controls working.

Very Poor range after installing new battery

Hi guys,
I recently took apart my moto 360 2nd gen because the battery wasn't holding a charge, and after I installed the new battery, I noticed that the watch's bluetooth range was extremely short. I mean, I have to have it next to my phone (Galaxy S9) in order for it to get a bluetooth connection. I also tested its wifi range, and that has also taken a hit.
Any ideas?
Thanks.
Hi Liam. Same happened to me.
Did you find a solution? I suspect is may have something to do with Bluetooth/wifi antenna... I tried to look into internet for schematics or something like this, didn't find any.
The antenna is that sheet of metal paper around the case, it can get loose when putting it back.
Look for a full tutorial that includes the display and try again, if it was damaged you can try with a piece of foil to increase the surface. I have done this to notebook wifi antennas.
