[Q] WiFi issues with Sd-HC-card - Acer Iconia Tab A100

Hello,
I have a weird problem. Today I inserted my new Samsung microo SDHC card 16Gb into my iconia a101. Now I have the problem, that I am not able to connect to my Wifi, when the card is inserted. When I remove the card I do not have any connection problems at all. Maybe anyone has a solution to this.
thanks in advance and kind regards Akku

That's strange. Here's a possibility... maybe the antenna connector popped loose and is making intermittant contact. I know that the antenna connects relatively close to the SD card slot, so it's possible that it loses contact when a card it inserted. In the link below, aznmade disassembled his A100 due to a wifi problem, so you might want to follow his walk-through to see if something's loose.

Thanks for your quick answer,
but that's most probably not the problem. When I remove the card, connect to my router and then reinsert the card, the connection stays stable. I also tried other sd cards, but all showed the same behaviour except one. The card I am able to use is a faked china 8gb sd card. Faked means that it is a 2gb sd card, but shows as an 8gb. That means if you write more than 2gb data to it you will override existing data.

Have you tried reformatting it with fat32?

Sure. The card itself is recognized by the tablet and R/w is possible. But the wifi refuese to connect when the sd card is inserted.

It seems to be a general problem - if you look for reviews on amazon, some buyers have the same problem... very strange...

According to the Acer Support with the update to 2.004.02 (A101) the issue should be resolved... any feedback on this?

Change the channel!!!
I had the same problem. I was on the road for a couple of weeks and purchased a PNY SDHC 8g for my a100. Didn't have a problem until I walk in the door at home. Then wi-fi started connecting and disconnecting. I fired up the hotspot on my Razr and bingo the a100 liked that much better than my net gear router. So I compared the configuration of my Razr to the Netgear Router and found that the router was set to auto channel. I changed the channel to 1 and a100 connected and was very happy. I am sure there is issue with the addition of the SD Card installed but it certainly isn't a hardware issue so keep the tools in the tool box and try checking the router config.

What another forum found was that it depends on the type of SD card - I have a Trancend SD - no problems - the same tablet with Sandisk SD - no connection... whatever that means

Sandisk SD Wi-Fi and Dlink Access Points

Hi, Does anyone know if the compatibility issues between the SD wi-fi card and Dlink 802.11G/B mixed mode wireless routers/access points has been fixed yet? Namely the DL-624+, DWL-2000AP+, DSL-902, DSL-604 AirG+ family. I have the DWL-2000AP+ and have been trying to get answers out of sandisk and dlink with no joy. Apparently there are problems because the SD card needs to work in B only mode and the dlink kit only supports G only or mixed mode.
Has anyone on here go the SD card working with any of the dlink kit mentioned above and if so what settings do you have to make on the access point and within the SD card drivers?
I would like to get the Magician and the Sandisk SD card but if there are problems with that combination and my wireless access point I with probably go for the Blue Angel.
Cheers
mixed b/g is not a problem. ive got sandisk sd card and a adsl router mixed b/g and no problem to connect. try this solution: uninstall sandisk sd driver and install drivers from other sd card that has the same chip: www.socketcom.com. this driver is totally compatible and woks much faster than original one. i read that solution in a spanish forum on pda tsm500 (the same model as xdaII).
good luck
Thanks for the reply, do you know if people are now getting success with the Dlink wireless mixed B/G routers/access points?

CoPilot and Micro SD Card

i have used the micro SD card to install Copilot and although the installation was done to the phone rather than the storage card it still requires the storage card to run.
Is there a way around this and run copilot without having the micro sd card in as i want to be able to have CoPilot and also get a new micro sd to store music etc on.
Thanks,
Chris
I dont use copilot myslef I use tomtom. However I would suggest that the program and maps voices etc will be to large to fit on the device, why not get a 2 gig micro sd card and have your music on it aswell.
As I said I dont use co pilot but I cant see you getting everything on the device. I did read somewhere that you can get a 4 gig card but never seen one myself or indeed have never had confirmation it will work.
Hope this helps
Never thought of transferring the Copilot SD data to a new bigger card through the PC as i thought it was too small but with the adapter will obviously fit in the card reader no problem. Thanks alot

mini usb and micro sd card slot problem...need help plz

First time poster here. I've owned my htc excalibur for a 1.5 years now running WM6 Kavana (got instructions off of youtube). for about 6 months now, my micro sd card slot hasn't been working. I tried using other micro sd cards and still nothing. My card works perfectly fine when I put it into my laptop too.
The second problem is that when I connect my excalibur to my computer, I don't get access to it like another drive so I can't get my pictures off of it or load on new music or docs. I have windows vista on my computer (unfortunately).
Thanks for any and all help!!
Wow this is weird. I have none of the problems you face.. I don't get how the Micro SD card isn't working. I actually bought a new 2GB card on thursday, and it works just fine. Don't know if this helps, but I'm running the Rose rom, and I'm also using Windows 7 beta. Do you think your problem is related to your computer's/phone's settings? I think you have to enable Advanced network functionality. Again, I have no issues..
i used to get both of those screen's too but for some reason now it wont recognize the phone is attached. i can still charge it by attaching it to my computer but no drive recognition. can you explain the advanced network functionality please?

On your phone, head off to Start>Settings>Connections>USB to PC>Check enable advanced network functionality. If that doesn't work, I don't know what will.

16 GB micro SD card causing file explorer to crawl

i have a SanDisk 16gb micro SD card and recently it has been making file explorer crawl and crash when im trying to navigate my data. i tried using total commander to access the memory card hoping that it was just file explorer giving me a hard time and it is doing almost the same thing in total commander (it is slightly more manageable in total commander) this did not start happening untill a few weeks ago. is there a chance that a corrupted file would be causing this issue or possibly i just have the card too full up? (its not at capacity yet but it is about 1 gig away)
is anybody else having this problem or does anyone have some insight for me? any help is much appreciated.
Chances are it's only a Class 2 card. Those are extremely sllllllooooooowwwww.

correct, it is class 2, but it used to be no problem whatsoever untill a week or so ago, anyone else got any clues?
It could be a combination of the fact that it's Class 2 and you loaded it to near capacity. I wouldn't think a corrupted file could do that, although I might be wrong. It could also just be a bad card. I've gotten a few that work fine for a couple days and then stop working completely. I would go with a higher class in the future (or a lower capacity Class 2 card).
Perform a CheckDisk/Scandisk(equivalent for your OS) on the card either via a Card Reader w/ an adapter, or connecting your phone to your PC in Disk Mode. Kind of fishy that it would happen all of a sudden. Flash media doesn't have noticeable file fragmentation issues.
You could also back up everything you have on the card, reformat the card, and reload everything back to it.
Hopefully this may help.
thanks for your responses, i will definately buy a higher class card in the future. how exactly do i perform that scan on my card though? i have an sd adapter so i can plug it directly into my computer. i use vista for my OS

Plug the card into the adapter, and in file explorer on your PC, right-click on the drive that is the SD card. Choose "properties", then the "tools" tab. There you will see the option to "check this drive for errors"
And for future reference, this is the same procedure you would use to do a "chkdsk" on any drive connected to your pc. It will check for signs of defects to the physical media.

Unable to copy files to phone's external SD card

IMPORTANT UPDATE:
So, I just removed the Exchange email account that enforces full-phone encryption, and formatted the external SD card, and now copying to it works perfectly fine! WTF! Isn't copying to the external SD card supposed to work even if the external SD card is encrypted???
ORIGINAL POST:
At some point in the recent past, the ability to copy files to my phone's external SD card ceased.
I will preface this post with the fact that I have two external SD cards:
1.) 32GB card that LG provided with the phone (via the rebate offer that included the 32GB SD card, the spare battery, and the charging cradle).
2.) 64GB SanDisk Ultra that I bought separately.
The 64GB card worked fine when I first bought it, which was shortly after buying the phone.
As time went on, I began seeing errors to the effect of "SD card unmounted unexpectedly". This occurred most commonly when browsing the songs on the SD card in a media player, for example.
I'm not sure if this started before or after I began encrypting the contents of the external SD card (my work's Exchange server began enforcing encryption of all storage on the phone).
When I grew sufficiently tired of the unexpected unmounting behavior to retire the 64GB card and try the 32GB card, I was somewhat surprised to find that the 32GB card is fine and never unmounts unexpectedly.
I thought, "Well, at least the problem is solved. Maybe the 64GB card is bad and I'll mail it to SanDisk for a replacement." Wrong.
While the unmounting no longer occurs (maybe the 64GB card really is bad), I can no longer copy files from my computer (or any other computer that I've tried) to the phone's external SD card.
I have tried with both the old/broken 64GB card and the 32GB that still seems to work fine in all other scenarios. Both cards exhibit the exact same behavior, which makes me think that the inability to copy files to the phone's external SD card through the included USB cable is unrelated.
I have tried from Windows 7 and Windows 10, with both SD cards, and I've repeatedly tried formatting both cards (while inserted into the phone). The result is always one of two things:
1.) Cannot copy [file name] The device has either stopped responding or has been disconnected. -> Stop copying -> Skip this file
2.) The copy dialog appears, and the progress bar begins to move, but it stops either immediately or about 5% of the way through (no matter how many files I'm attempting to copy of how large they are), and it hangs for 5-10 minutes, before it finally times-out and asks me if I want to skip the file or try again. If I try again, the behavior is exactly the same.
I even tried connecting my phone to a Mac laptop running the latest version of Mac OS, installed the driver package from LG, and when I open Android Transfer, the dialog tells me to connect my phone, even when it's already connected. Disconnecting and reconnecting the USB cable changes nothing.
For whatever it's worth:
1.) I'm able to copy files to the internal SD card with no problems whatsoever on the Windows 10 machine.
2.) I'm able to move/copy files from the internal SD card to the external SD card, but only if I use LG's built-in File Manager application. I suppose this is to be expected in Android 6.0 because non-system apps, such as FX File Explorer, lack permission to write to the external SD card.
3.) If I try to drag a file from the internal SD card to the external SD card from within Windows, a "Copying..." dialog appears, but it says, "Waiting: VS986 is busy." and it hangs indefinitely, until I click "Cancel".
4.) Enabling USB debugging doesn't change the behavior.
5.) It seems like the first time I connect the phone to a given USB port on the computer, Android prompts me to allow the computer to access the phone's storage. Whenever prompted, I always click "ALLOW", as pictured in the attached screenshot.
6.) I'm trying this in MTP mode, as that is the only mode in which my external SD card shows-up within the "VS986" device that is mounted in Windows when the phone is connected and unlocked.
7.) I'm using the original LG USB cable that came with the phone.
8.) I've tried all different USB ports; it doesn't make any difference which one I use.
9.) I'm able to copy files from the phone's external SD card to the computer without issue. (Well, "without issue" is an overstatement, but it works most of the time.)
10.) Software vitals are attached in screenshot.
What the hell is going on with this phone? I just performed a factory reset, to ensure that I'm starting with a "clean slate", and it didn't change the behavior.
As a final point of note, I have not tried copying to the phone's external SD card before encrypting it. I will try that and post back (as big of a pain in the ass as it is).
Thanks for any insight here; I'm about to throw this thing off a pier and file an insurance claim.
Have u formatted the sd card clean then tired to copy files over that's the fix I've found for the issue
Junk card
Had the same issue with a SanDisk card it has bad sectors on it call them up get another then stop buying sandisk TLC/MLC cards and get SLC cards yes they cost more but are far less likely fail with large files read and rewrites. I use Silicon Power UHS-3 and have had no issues at all even with the UHS-1 version of the same brand.
SLC is an abbreviation of 'Single-Level Cell':
SLC memory stores one bit in each cell, leading to faster transfer speeds, lower power consumption and higher cell endurance. The only disadvantage of Single-Level Cell is the manufacturing cost per MB, meaning that the SLC flash technology is used in high-performance memory cards where speed and reliability are important.
MLC is an abbreviation of 'Multi-level Cell':
MLC memory stores two bits in each cell. By storing more bits per cell, a Multi-Level Cell memory card will achieve slower transfer speeds, higher power consumption and lower cell endurance than a Single-Level Cell memory card. The advantage of Multi-Level Cell memory is the lower manufacturing cost. MLC flash technology is used mostly in standard consumer memory devices.
TLC is an abbreviation of 'Triple-level Cell':
TLC memory stores three bits in each cell. By storing even more bits per cell, a Triple-level Cell memory card will achieve slower transfer speeds, higher error rates and lower cell endurance than both Multi-level Cell and Single-level Cell memory cards. The advantages of Triple-level Cell memory are that the memory chip will be physically smaller than SLC and MLC chips for a given memory capacity, it requires less power to operate than MLC memory and is cheaper to produce. TLC flash technology is used mostly in low-end memory devices where speed and reliability are not important.
