[Q] Wifi & Bluetooth signal strength diminished - Sprint Samsung Galaxy Note II

Hello All,
Last night I opened up my Note 2 and replaced the vibration motor. Since then i notice a significant degradation in my wifi signal strength and throughput. Also my bluetooth headphones cannot reliably stay connected or stream audio effectively.
I was wondering if anyone knew which connection on the motherboard is responsible for these two radios so that I can re-open the phone and inspect?

but im still searching for a solution

One x Bluetooth signal quality issues?

Since swapping from my GS2 i have noticed signal loss issues when streaming music from my HOX to my Bluetooth headphones. Previously i used my GS2 everyday to play music via one of 2 pairs of Bluetooth headphones whilst training. Never had any issues with signal loss even when I left the phone on the other side of the gym temporarily. Now when I use my HOX I get massive skips sometimes if i merely put it in my pocket upside down or more commonly if i put my hand over the top end of the handset or swing a weight and/or my arm etc over top of it. I swapped firmware to aokp to see if it helped and it may have slightly but still it is unacceptable for a newer handset to do this let alone a flag ship. I have seen some others noticing this too and sorry if it has been already discussed lots, just wondering if anyone has found a fix or workaround? Or do I just need to go back to Sammy and swap to an s3?
Thanks in advance

Go swap it for an S3. You'll fit right in over at the whiniest forum on xda.
Chill, no need for that dude I'm not trolling or IMO excessively moaning over nothing as it seems like I have a legit hardware issue I was trying to work around, other than that I'm very happy with my change back to HTC.

I've had similar problems with my bluetooth headset on my One X - fairly frequent signal dropouts which appear as pauses / skips in the music. This is in contrast to my HTC Desire which always had a good signal to the same headset, and very rarely (if ever) dropped out.
i use bluetooth headphones when training and also catching train to work and i notice it too mate. In fact i had something similar in my desire HD. The range of the signal and also strength is exremely poor in recent HTC phones for some reason. I thought it may be my Senheiser headphones, but i tested them on my friends SG1 and they work perfectly even at long ranges, no skips or pauses.
I don't think there is a fix as i think the problem is in the poor hardware itself......hopefully HTC address this in their future phones
Cheers for the replies guys, yeah assumed that was the case just was hoping I could some how increase the buffer size or something along those lines so when the signal is interrupted it could stream through it somewhat. Obviously this would only work if the interruption was relatively short but still may just be enough for a bit smoother playback, providing this was possible at all in the first place of course. I tried to fiddle with power amps settings to do this in a very basic way but had no real success.

It's probably obvious, but have you tried unpairing and then re-pairing your BT headphones? I used to have a similar problem with my Legend, and doing that solved it (along with rebooting the phone). BT reception on my HOX has been near flawless, on the other hand, so not sure what causes your problems. Hope the above helps.
PS. The HOX does have skip issues when turning the screen on/off, and I suspect this has to do with switching to and from the companion core. Wonder if that will be fixed in JB.

My bluetooth headset signal is getting worse and worse.. even having it about 30cm away it'll still lose signal.
and if i put it in my pocket and walk, basically every step i lose signal...
I assume it's software issue and it didn't have such a bad problem when i was on ICS
This is a hardware issue

[Q] Solutions for OUYA's weak wifi?

Got mine yesterday. Biggest complaint is the wireless receiver is pretty weak. I had the OUYA upstairs where my phone, laptop, and ATV2 all got a strong wifi connection. However, the OUYA kept dropping the connection every few minutes. I had to move it downstairs, in the same room as the router.
Has anyone found any solutions for increasing the OUYA's wifi range?
noticed the same thing about weak wifi signal...wonder if it's a hardware design issue or a driver issue.
Yeah, I've noticed the same thing. I actually have to AP's - a netgear router in my outside office where my cable comes in and then a WRT-54g setup as a repeater to serve my house. My TV, Living room PC, Wii, tablet, and phones all get a great signal off the WRT and the Ouya even reports it as a good signal - but refuses to connect sometimes and drops the connection all the time. Oddly enough the Ouya has an easier time connecting to my netgear router even though it shows a "fair" signal at best. So I'm thinking maybe the Ouya is just kind of picky about what it likes to connect to. But I also usually see at least 6 AP's in my living room and the Ouya only picks up my 2 - so it does seem to have weak reception.
Thinking I'm going to reconfigure my network this weekend. I've been working from my official office more lately and don't use my outside office much at all anymore so I'm probably going to reverse things and put the router in the living room so the devices in there can be hardwired and the office will run off of WiFi now instead. Been thinking about doing it for awhile the Ouya is just the final straw.
One thing I've considered doing is using the Ouya out of it's case to see if that improves it's reception any, it's really easy to remove from the case (4 hex screws on top then the board just pulls out with a gentle tug - but be careful not to get the grounding clip caught on the lip the lid fits into) and with the case being aluminum it could potentially be attenuating the signal. Since they released design files for the case if running it out of the case helps it wouldn't be that hard to get a plastic case made for it...but I'd hate to have to go that route just on principal.
For whatever reason I did have better luck getting the Wifi to connect when I went into Mange->Settings->Advanced->Wifi and used the unskinned android settings menu to setup my wifi. using the Ouya's menus I was never able to get it to connect to my WRT repeater. But using the stock settings I was. Not sure why that should matter but there it is.
I think it is a driver issue. Install speed test and seer what results you get. I get higher upload speeds than download speeds and using Ethernet it ifs no where near where it should be. Not enough off an improvement to make connecting it worthwhile.

Someone else posted somewhere, that they turned off ethernet once they had wifi connected, then hard reset the Ouya, and it sped up the wifi connection. I can confirm this for myself as I tested a file transfer through ES File Explorer and it jumped from 3 kbps to 45 kbps. Still a lot slower than my other wifi devices in the same room, but at least it became usable.

Hard reset as in simply pressing the power button, or by disconnecting power?

Try just rebooting (hold power for a second and select power off). It's never a good idea to just pull the plug.

Yep this.
Didn't really have enough difference for me. Range and speed are still flaky if I'm more than 20 feet from the router.
I'm still waiting for OUYA to recognize this as a problem, and hopefully put a stronger wifi chip in for retail. OUYA support has told me that weak wifi on the OUYA is not a widespread issue, so seems like they just want to deny the problem.
They either need to:
Increase the power to the wifi chip
Use a better wifi chip
Use a wifi chip that can utilize a wire antenna for better range
Build in drivers for some external wifi adapters
Sucks that I'll have to get an wifi repeater, wifi bridge, or something else to get the OUYA working in a room where my laptop, ATV2, phone, and tablets all work fine.
Mine dropped out completely when I tried to login for the first time after updating, had to turn the Wi-Fi on/off a few times to get it to work... and it's sitting 20cm from the router!

Yes, mine is extremely flaky still as well. So far I'm pretty frustrated with the problems that are arising with Ouya, which is too bad, because I actually really really like it should far. I honestly wish I'd waited until retail now, because I would have had a better/more finished product for less money and hassle.

Is anyone still experiencing Wifi problems? I just got mine hooked up today and had a ton of problems until I updated the software and reset, have not had a single connection issue since.

No. Mine worked out of box. I have an Ouya1-b
I have experienced zero issues, but I have an enterprise class dedicated wireless access point (a Ubiquiti Networks Unifi AP if you're curious), so I get full bars everywhere in my apartment and coverage like 20 feet out into the parking lot outside my apartment.
Since I also have a gigbit network everywhere in my apartment, I have generally just been disabling the WiFi.
One sort of issue I have noticed with the networking on the Ouya is that Android was built to allow for multiple network interfaces, which is only natural given that pretty much every smartphone has WiFi and also some sort of "mobile" data as well. Turning off the WiFi doesn't seem to always "stick" for whatever reason, so I may end up just "forgetting" my normal WiFi network in the network settings to prevent the WiFi from being used.
I have been toying with the idea of taking the Ouya mobo out of the aluminum casing, as its trivial to do and many people have speculated that the case is causing BlueTooth and WiFi signal issues. I HAVE experienced some weak connectivity to the controllers, and wanted to isolate the issue to either the controller or the console.

I tried taking it out of its case, and it didn't have any noticeable impact on my WiFi.
what about Bluetooth? Thats the thing that would effect the controllers, which are the element which is having a reception problem...

I didn't know the case was aluminum. Seems kind of odd choice of material. The Ouya isn't handled much, so there's no tactile advantage to using aluminum. The Ouya has a cooling fan, so heat dispersion isn't a huge issue if they chose plastic instead of aluminum.
What's the wired network speeds like? Can anyone test it?

Since switching to Ethernet (and turning off WiFi) things go much faster. Streams 1080p movies without an issue, and game downloads are pretty fast. Thumbnail loading on the OUYA menus still could be faster, but I think that's more of a firmware issue with the way those are handled, rather than internet speed.
i think the worst part is that they refuse to fix anything or acknowledge the issue. This topic is covered on several other websites, even their own support website. Ouya seems to keep saying this isn't a global issues. so does that mean in the future if we are having other issues they have to be global in order to be fixed or updated?
This seems crazy. i have 4 devices right next to the ouya and my ouya download speeds are less than 107 kbs, but all my other devices are between 5-10 mbs.
i tried to erase everything, reboot it, and now i cant even connect and maintain a wifi connection and get past the ouya upgrade page on set up. It says im connected, then timesout and says i have no wifi.
and to make matters worse im not really close to a ethernet connection, my router is upstairs and my tv is downstairs.
This just seems crazy that a company could releases a product in such an alpha stage and not take the people who helped make them successful seriously.
I've seen speeds of nearly 2-3mbps on my Ouya, which is consistent with my Nexus 10, laptop, and others (no way to install steam to see if Ic an get Steam's stupid 7mbps...)

[Q] Poor data/signal after repairing charing port.

Okay, so last night I successfully replaced the charging port on my Note 2. It wasn't malfunctioning, it was just extremely loose and was hard to keep a charging cable in.
Before putting the device back together I made sure the antenna cable and all other cables were plugged in and snug.
Since the repair , my device seems to be getting horrid data. Normally I would get LTE speeds of 20mbps+ up and about 10 down, now I'm getting 5mbps down and about .05mbps up....
The signal in the status bar goes from LTE to 3g and DC (cyanogen mod, not sure what that means).
The first night I didn't notice any problems as I was at home and connected to my home WiFi network. But when I woke up the signal was awful. I can make calls and text sometimes, in some area the signal bar has an X over and has no signal at all.
Has anyone experienced this or have an idea of what might be wrong?
Any help at all would be greatly appreciated!!!
P.s. the replacement part was specifically for my device, t889.
Okay, so this morning I downloaded and flashed the most recent modem for my phone and the signal strength seems stable, LTE download speeds are around 25 to 30mbps and my signal isnt constantly switching around. However the upload speeds are still around .01 - .05 mbps which is nothing compared to my old speeds of around 5mpbs - 7mbps.
I honestly have no idea how the hardware interacts in the phone, but would the charging port that I replaced possibly be faulty? I know the antenna cable plugs into it, and it has me thinking there is some part on it that is malfunctioning. But all this is just a guess.
I'd really appreciate any feedback.
Thank you.

Bluetooth Concerns

I have 2 issues with Bluetooth on this phone. (Verizon version)
First, it does disconnect and occasionally with my Kinova head set. (Never with the M8)
Second, it has horrible range compared to my M8. I put the 10 in the exact same spot on my toolbox at work as my M8 with the same headset and I don't get nearly the same range as before. I honestly could go about 30-40 yards with the M8, I am lucky to get 15-20 with the 10, sometimes it even breaks up just 15 feet away! One of the greatest things I personally liked about the M8 was how far bluetooth range was.
Hopefully there will be an update to improve this.
I agree BT is kinda ****ty. It doesn't totally lose connection to my truck stereo but it starts to glitch out if I handle the phone while streaming music has to be put down to keep a solid signal

that's odd, I cant comment on the range. but ive streamed for a couple hours, while using as a mobile wifi hotspot along side the streaming, while driving on a long drive and it didn't have one hiccup, worked the whole time. also received a couple calls that switched over audio perfectly to the stereo speakerphone and then switch back to music without issue.
BT audio is used everywhere I go in my car, I cant stand normal radio.
I have Verizon version
It could be my radio i have an alpine 265bt but it also happened in my wifes Malibu 2015 on stock radio also. It will stream fine if i just set it down but once i start using the phone will streaming it seems to interupt the signal. Its weird i have to kinda shake the phine to stop the glitch
Sent from my HTC 10 using Tapatalk
I've also found the range to be rather poor, and also sometimes connectivity is temperamental about what it will connect with.
BT has worked well for me. At least in my car, it's probably the best sounding implementation I've used to date.
My problems have been with the WiFi - all the problems you guys have mentioned.
BT Power
Another thing I'm noticing is that in the battery-usage stats, BT power consumption is considerably higher than the Screen's!
On my M8, it never mattered whether I left BT on or off as far as battery life was concerned.
FYI Alpine recently released a bt firmware update for my 149 that really helped. I've had excellent luck thru many portable speakers like TDK and SB roar2 but the car was glitchy. Now it's smooth and fast. No issues here

BT loses connection
I have a similar problem but it happens when
1) Phone lose signal due to poor cell signal.
2) When Wi-fi automatically connects (when I drive into my garage).
When this happens internal speaker kicks in. Only way to fix this issue is to disable and enable Bluetooth.

Poor wifi signal issue

Hi all!
I would like to know if anyone here has noticed if their Mi5s has a poor wifi signal strength compared to other phones they had.
I've used a Samsung Galaxy 5 NEO as comparison. While the samsung brings me nearly full speed at a distance of 10-15 meters from the wifi device, the mi5s just brings me 1 or almost zero if I move just 3 meters far.
There's something I did that maybe has broken the wifi signal. I had an accident where some coffee was spilled in the phone, and I had to unassemble it to clean the speaker that wasn't working properly. I just cleaned the speaker module (it can be deattached) carefully with little water and it started it to work good again. But not sure if it was because the unassemble but I noticed that the wifi signal was pretty poor comparing other phones.
I'm starting to think in changing the rom now with all the kernel hype and I would like to know if I'm the only one, because if it is that case, I'm probably going to unassemble it again (not a easy task) and recheck if I missed to connect something, but if I remember correctly, the wifi antenna is nothing more that just a metal part attached to the board.
So. Am I the only one who noticed this or just my xiaomi is broken?
many thanks!
Mi 5S have good Wi-Fi module, at least better than Samsung Galaxy S6. I think that your problem is connected with that accident. Metal can oxidize when the water touches it. I think that you have something like this with your Wi-Fi module connection.
