Hey all, new to the forum and new to the shield k1 tablet. Feeling pretty frustrated. Need help. I got the shield delivered from Amazon on Friday the 18th December, nice looking tablet but issue right out the box continues to be wifi connection/signal. I managed to get it connected in the home but if I walk further than a room from the router it disconnects. At first I figured it's our fairly old router but now I've taken the k1 out in public places to connect to wifi and it still fails. At most it "connects" but also displays a exclamation point. Is it a problem I can solve or should it be returned? I've seen some minimal threads with the same problems. Also one other issue is the power on button is flush with tablet itself, not really a deal breaker, just annoying. Thanks for any input.
My Sheild K1 tablet has different wifi issue.
It always connected to my wifi network with
excellent signal strenght. But sometimes the
internet speed drops very low. Normally it connects
at 130 MB/sec and would drop to 6MB/sec.
Rebooting the tablet and give it sometime to return
to normal speed. Also, setting the power/performance to max performance help
to keep the tablet from dropping internet speed.
Just updated this tablet to Android 6.0 and
the wifi connection speed seem to be more stable.
Enjoying the performance of Marshmallow .
Also I keep my tablet inside a protective case.
bump:
I've had similar issue as well. The tablet seems to be able to accept lower strength than other devices. For example, In my bed-room, my phone shows medium signal strength but the tablet only shows low signal strength. and moreover, my phone will still work with when it receive low signal, but my tablet won't work once the wifi signal is low.
I opened back-cover to see if i can make any improvement to the wifi antennas, but I found out that the wifi antennas are built-in to the speaker boxes. Is there any way i can make the tablet receiving better wifi signal? Thanks.
The WiFi antennas **are not** built into the speaker boxes. If you hold the tablet in portrait mode, front camera at the bottom, the antennas are at the top left corner (below the speaker). And if you cover that area with your hand, you'll have a poorer WiFi connection.
Thus the front camera should **never be** at the top when holding the Shield in portrait mode!!

Is anyone having issues with WiFi? My charge seems to take forever to connect to my AP and signal strength is very low.
Even in the same room as my AP I couldn't stream to my TV via DLNA without it stopping to buffer ever 10 seconds. It's really disappointing.
I have this problem, coupled with horribly slow 3g data speeds in parts of my house, makes this worthless. I played with the Infuse for a week and although similar speced, it is superior to this phone.
Anyone else seeing this? I am trying to determine if there's just something wrong with my phone or if this is systemic. I'm willing to swap out for another Charge if it'll fix my wifi, but i'm not going to spend the time redoing my settings the other will just have the same issue.
Sounds like it may be a phone issue. I get better wifi signal with my Charge than with my Fascinate, and better signal strength in general.
Not seeing that problem either on my Charge. It connects quickly via my home wifi.
my charge connects instantly to my wifi and has no issues with it
Same no issues here.
But my router is downstairs and upstairs in the furthest corner away from it I get very spotty signal. it fades in and out from 1-2 "bars"
Before I exchange my phone again, I was wondering if there is 100% confirmation of this issue. I use my phone with WiFi in landscape mode, so this problem is really bothering me.
If you not having the issue, why worry about others?
I am having the issue. I apologize if I wasn't clear, but I had said that "this problem is really bothering me" as in it is literally bothering me.
No i don't have this issue. Can't even make it happen. If that's couse of the signal strength i have on the wifi's i use it on, who knows. But it's never been a issue here!
Can't say I've found it an issue but I don't use my phone in landscape for anything
Death Grip.
Hi OP, Ive had this problem when browsing in landscape, a certain grip can knock WiFi signal strength right down or if its already low completely kill it. Another thread on here advised
Settings - Wireless and Networks - Wireless Settings - Advanced - Tick Best WiFi Performance.
This seems to have made a significant improvement and TBH I havent noticed a change in battery life.
Hope that helps.
(Never had the problem WRT 3G/4G)
Third Sensation also has death grip issues, performance setting doesn't seem to help substantially. Bummer. I guess I'll just have to find an new handling position when reading.
no problems here, works fine

Are you using it in landscape mode and gripping the left side (near the HTC logo) with your left hand? Also, you must be a reasonable distance away from your router. If you are within 8 feet, the drop isn't noticeable.
When I first got the phone I was staying in a hotel. WiFi dropped constantly if I held the phone in my "normal" grip. Now I'm at home and I'm unable to kill it, no matter how I hold it.
Yeah I have the problem too when I use it in landscape mode sometimes it'll be so bad I'll be put on 4g thinking if I should replace it I also have the lock screen issue is there really sensations out there with absolutely no death grip?
Got my Sensation yesterday. Just tried the death grip test and can't make it drop below 4 bars no matter how I hold it. This is with "Best wifi performance" unchecked. Wifi Analyzer does show a drop in signal strength of about 20dB, but I never lose connectivity. Played a YouTube HQ video and it never stutters in landscape, with both hands wrapped around the phone. Based on the signal drop it's very likely that in a low signal location holding it certain ways would cause connectivity loss. But that's very likely true of any phone.
So, being conservative I'd say at least some Sensations with some routers do not have the problem.
Hi. I've heard that there may be a difference in the models. Some have 3 pins connecting to the back cover/antenna and some have only 2 pins connecting to the cover. If people could post if they're having problems and how many pins they have under their back covers there could be a link?
i just purchased my phone last Saturday, and i am already on my second phone. they both exhibit this "death grip" issue, and the problem is very apparent--enough to render the wifi useless for me.
it does seem to be based on the wireless AP though. i do not experience an issue at work, nor at certain public wifi points. however, my cheesy home wireless AP seems to have a problem, and i suspect most hotel wireless APs will as well. since i travel for work, this is a problem.
i was informed by a T-Mobile employee that this is a known issue with the first generation of these phones. phones manufactured after June 1st are supposed to have resolved the problem. i am currently waiting for their shipment of these new phones to arrive so that i can get a replacement to see if it truly does resolve the problem.
When I throw my gorilla grip on my sensation (just below the point of annihilation) I have no signal issues. No change.
Maybe only certain sets have the issue, because I haven't faced it at all. I browsed the web using WiFi and had no issues. I have issues with the signal, but that is more due to my service provider and where I work. Otherwise, no dropped calls and surely no deathgrip.
My Phone has the. Issue. When I hold it with a death grip, I can see my wifi bars going down. I don't know how it affects the practical use and the internet speed.

That would be 'signal attenuation' rather than 'death grip'.
I don't have any signal attenuation on my Sensation. It does not matter how I hold the phone. My phone is dated 6/6/11.
Sent from either my N1, NS, or Sensation4G....
My first Sensation had the best screen but the worst connection with the death grip. My second handset has the worst screen but the best connection with death grip. Much like ALL android phones, you always have to compromise with some feature/defect.
Anyone having wifi issues ? I can connect at home no problem, wap2, range seems fine. At work we use wap2 enterprise. Seems to connect for a 1 min or so then drops connection. It shows that its connected just doesn't seem to send/receive info. Thanks
First impression is that it might be a tad weaker than the old Tab7. Weaker reception in parts of the house where the Tab7 had no problem. But the signal certainly is stable.
The one I've tried at best buy definitely had shoddy wifi. The 10.1 and 8.9 both connected to the bestbuy wifi, but the 7.0 had trouble.
signal weakens when your holding the lower left side of the screen on portrait mode. Thats what i experience.
Its a great tablet for sure but if the only major way to connect to the web has poor signal that can be an issue. How does the 8.9 tab compare in performance to this 7.0 plus ?

I can back this up also,I always get a better signal when I hold from left to the right side, antennae must be around there somewhere

Hi,
Some users on a Dutch forum reported a loss of signal strength (both Wifi and phone) when the back of the Moto G is covered by your hand. I checked and I can repeat the problem. If I cover the lower half of the back, my carrier signal goes down by two bars. When you cover the upper half, the Wifi signal drops substantially.
To test if this was a real loss of signal instead of an issue with extremely sensitive bar display, I have installed Wifi Analyzer. It shows a drop of 5 - 10 dB on the Wifi signal so its a real issue.
Do others have the same problem or are there some faulty units around?
I cannot reproduce this. XT1032 8GB retail GB version.
16GB UK - I can get WiFi to drop by covering the back.
Mobile signal does not drop though.
Doesn't worry me as I don't press my hand on the back when holding the phone.
I can also get the signal to drop wrap my hand around my routers antenna.
I would think it's quite normal for a signal to drop if you cover the antenna or receiver. The phone has to have the receiver somewhere and wherever they put it you will be able to cover it if you try hard enough.

Remember the 'you're holding it wrong' defense of Steve Jobs when the iPhone dropped its signal?
I don't need to press, just by holding the phone in a natural way to take a call the signal will drop. And like I said covering only half of the back is sufficient.
That Debaj can't reproduce it, suggest it's not in all Moto G's
Moto G 8GB German, left-handed (in case it makes a difference) and it occurs most often when the signal is at 4 instead of 5 bars to begin with.

Mine does the same to an extent but not nearly as bad as my old phone. Two bars missing sounds quite serious, though. Have you tried taking the rear cover off and checking to see what it does?
Wifi signal drops 1 bar (from 4 to 3) when covering top of the back. Not a big deal to me
Mobile signal doesn't drop when covering the bottom of the back.
Moto G 8GB, British retail version running US global 4.4.2
EDIT: Holding the phone in the left hand drops the signal by about 5dBm. Holding the phone in the right hand leads to no loss in signal. The only way I can get my Moto G to lose some signal (from 4 bars to 3) is to hold the phone in my left hand AND cover the bottom bezel with the right hand. It drops about 15dBm.
Thanks chowy993, scott_doyland, WabbitKiLR and Debaj for your feedback.
I guess there is something wrong with my Moto as I have an 8-15 dBm drop on the carrier signal just by holding my hand it in the normal 'telephone position' (but not next to my head). I measured it with an app called Network Signal. It drops into the red zone at over a -100 dBm so its a serious problem which will cost me battery life and loss of connectivity in some places .
I tried this with my wifes Moto G and the wifi drops one bar if I put my hand over the back. The mobile signal remains the same. Then I tried it with my Galaxy S3 and got exactly the same result.
I posted a thread about this a short while ago on the 31st December: http://forum.xda-developers.com/showthread.php?t=2592673
I can confirm I have this issue too! I cannot do any video or voice calls over WiFi if I hold my phone in my hand. The connection repeatedly drops until I put the phone down.
As soon as I hold it, I completely lose all WiFi signal (I have full bars at the time), and can also lose all 2G signal too (from full bars to Emergency Calls Only). My only solution was to simply leave the phone on a surface.
Mine is being sent in for a repair tomorrow for this reason. But sadly it appears even if the phone is replaced/repaired, that this is simply a issue with the Moto G in general?!
Never experienced such poor problems like this on a phone before.
I have the exact same problem on my 8 retail UK version I posted about this here http://forum.xda-developers.com/showthread.php?t=2588286
And people were saying its the way I was holding my device. It isn't I can completely make my device lose signal just by being in a call. And cover the the bottom of device. It seems like there is a bad batch and Motorola needs to sort it. I'm on my 3rd device now and its still doing it. Gutted really because its a brilliant device. It seems to be the 8gig version having these problems I got told.

Cannot reproduce the issue at all, neither mobile nor wi-fi drops even with the back fully covered by both my hands. Held it like that for five minutes and no sign of it.

Count yourself as a lucky then I think I'm going to replace my 8gig for the 16gig.
Sent from Motorola G.
UK 16 gig model and I can get my WiFi to drop by one bar but mobile signal is unchanged no matter how I hold the handset. Bad news for u mate, sorry.
I looked into this problem.
Believe it or not, it seems to be down to the use of spray deoderant.
Most spray on deoderant using aluminium oxide. When it get's on your hands, and you hold the phone, the light metal coating causes a charge differential with the phone's antenna (basically your hand and the phone act as a single film capacitor).
This is different from the issue with the iphone, this was because the metal bezel of the phone actually changed resistivity when held directly with the hand, effectively changing the length, and therefore effectiveness of the iphones antenna.
I suggest washing your hands thoroughly. You can also use a multimeter on your hand, set to milli Ohms to see if you have an unusual resistivity (probably due to aluminium oxide).
Roll on deoderant is another good option.. Or just be smelly of course. I never wash, shower or using any cleaning products and my phone has perfect signal all the time.
mranonymous1 and maccboy2010 can you check if it's identical to my problem: holding the lower end is a drop in carrier signal, upper half of the phone: wifi drop ?

I no longer have my phone as it's in for repair. I can tell you though that for the week or so of use that it was awful. Mine was extremely sensitive that a video/voice call over WiFi would instantly end the second I even went near the phone/picked it up.
It was the WiFi dropping that was more of the issue for me than mobile network signal (I struggle to get 2G signal anyway where I live). But I could easily lose all mobile network signal from holding normally too.
Ok, I checked again and the problem only occurs if the signal level is not that good to begin with. It then drops enormously making calls impossible. Handsfree calling in the same circumstances is no problem.
When I am at a place with a strong carrier signal my hand hardly influences the level. So it's sort of a worst case scenario but it explains why others don't notice the drop.

Yes mine is the same as yours if I hold a the bottom signal drastically drops.

I can confirm covering the bottom drops my signal.

Also happens with my moto g. Covering the top indeed affects wifi and the bottom affects signal.
A lot of people have issues with the antenna on the Shield tablet. Some of us are able to block WiFi transmission or severely weaken it by putting our hand over the corner of a tablet (happens to me just by holding the tablet in portrait mode with the camera on the top).
I am a new member so can't link to the YouTube video I made demonstrating this phenomenon. I can't post a link because I'm a new user, but it's titled: Nvidia shield tablet bad WiFi design, don't buy a lemon.
Another YouTube posted a video a week ago showing the same effect. His video is called: Nvidia shield tablet, how to hold your tablet in your lap.
I'm on the 2.4ghz band in the video only a room away. Does it happen to you guys too? Do you have any other issues with the WiFi on this thing?
Thanks.
WiFi reception isn't as strong as other devices I have in the home, and I can decrease the signal by holding the bottom right corner when held in portrait in particular, but I've not managed to choke the reception entirely or have it be a practical issue at all.
I haven't notice any WiFi signal degrading when holding the tablet at all. but then again I have an AC87R router that outputs pretty crazy signal strength.
My router is ASUS top of the line AC router from last year, probably helping me also.
I'm on my second shield tablet and niether have had any WiFi issues. And I use a crappy centrylink router. Grid works perfect.
Mine has weak wifi and am going to get a replacement from amazon tomorrow. Hopefully it's just my unit. I may invest in a new AC router next.

I think I have problems with Wi-Fi too. For example, playing Modern Combat 5, connection is lost many times...Maybe it's a Gameloft problem...
Sometimes I have issues with downloads on Google Play too....
I don't know if it's a problem or not...or if it's a hardware or software problem...
