Help A 500 3.1 wifi problem

[tedpc01]

Hi, saw Acer had a patch called "Acer ICONIA TAB A500 'connect Wi-Fi unsuccessfully' patch" and it's located at: Download

 

[DrBobb]

Below is my original post following the installation of the official Acer patch for the Android 3.1 WiFi problem, as well as the next operating system update.

I have had further time to analyse the results and can now state that the patch and system upgrade (see below) do result in a system that works in a stable manner. The problem I found before was that a pure installation of the patch appeared to show the detected WiFi signals with greater strength than after the subsequent upgrade to the Acer_A500_4.010.40_COM_GEN1 system. It appears, to me, that the WiFi strengths reported are less after the system upgrade. But at least I can confirm that the WiFi does work after the full patch + system upgrade (different to the situation I reported in the original post). The situation seems to have corrected itself (maybe after a few restarts) and I am now happily using the system again (even if the WiFi strengths appear slightly lower).

So sorry for those who held off on the system upgrade. Go for it! And good luck to all!

Cheers!

As one of the first to report problems with the WiFi on the Acer Iconia A500 after the Android 3.1 upgrade almost a month ago I was relieved to finally see that Acer had released a patch (see acer.com, and go to the support/download section).

The patch includes instructions. What they forget to mention is that you need to disable or remove virus scanning/firewall software to get the patch to work. That's the first piece of advice.

I removed McAfee and NetQin anti-virus and finally got the patch to install. Worked well. I was finally able to connect to WiFi networks as before. 'Hoo-bloody-ray', I thought! Fixed at last (or so I thought!).

I have included the full patch update installation instructions at the bottom of this message. Now, my Australian purchased A500 was running the Acer_A500_4.010.24_COM_GEN1 system at the time.

The section of the instructions that related to the patch upgrade was:

"
C. Countries: Singapore/Malaysia/Thailand/Philippines/India/Vietnam/
Indonesia/Australia/New Zealand
- Affected OS versions:
Acer_A500_4.010.12_COM_GEN1
Acer_A500_4.010.24_COM_GEN1
- After installing the update, you are advised update your tablet’s operating system to:
Acer_A500_4.010.40_COM_GEN1
"

Note that the patch installation instructions recommended that Australian users upgrade their system after applying the patch. So, like an innocent newbie I decide that Acer can't be silly enough to make the same mistake twice.

....... WRONGGGG!!

Once the 40MB system upgrade to Acer_A500_4.010.40_COM_GEN1 had been downloaded and installed I found that I was back to 'square one' with the WiFi.

The WiFi is now dead AGAIN, and a new patch is once again required (as the old patch won't work on the updated operatng system).

So, by all means, install the update patch, but DO NOT, (repeat) DO NOT, upgrade to the next operating system! That's all the advice I have at the moment.

This problem at Acer has to be fixed. Not just the WiFi problem, but also the staff who let these upgrades, patches and dodgey advice be released. None of us in the research, IT and systems analysis community would condone the practices employed by Acer at the moment. Heads would 'roll'!

We require Acer staff to solve the wireless problem promptly and permanently, and practice what you preach (ie. test and retest your solutions, upgrades, patches and recommendations).

As a further suggestion, please consider finding a way to reverse system upgrades and allow for non-web-based system upgrades (for those without wireless access).


Cheers!

I am a new user, and appreciate the help you have given me with the same connection problem that everyone is having. Here is a little twist on solution from my location. I have 2 Wi-Fi hotspots in my home. The first is a Verisn router that provides a wireless G type connection, which I had no problem connecting to. My other hotspot is a Cisco Valet M20, with an N type wireless 2.4Gh connection that I could not connect to. I used the 2 reset fix with limited success. The tablet seemed to connect to the Cisco, but with such poor reception that it was not usable. I forgot the connection and retried a couple of times with the same poor reception results. I then noticed a drop down in the connection panel where you enter the wifi password that was set to manual. I changed the drop down to the push button setting, then went to my Cisco M20 and pressed the auto connect button on the top center of the M20. Almost immediately my Acer tablet connected and showed as excellent with better speed. I hope this might be of help to someone.

Jim, can you tell me specifically where that drop down menu is? I have to connect to the same type of router that you have, most of the time its a good connection and pretty fast, but some days it leaves a bit to be desired.

Thanks

This is what I did to setup my Wi-Fi connection. After performing the paperclip reset that was suggested while a connection attempt was authorizing, I did a Forget for my Wi-Fi name. Next I went Settings > Wi-Fi Settings > then selected my Cisco hotspot name. The connection box comes on screen. In the box next to Network Setup there is a drop down menu where I changed Manual to WPS Push Button. I then went over to my Cisco Valet M20 and 1) Pressed Connect on the Wi-Fi setup on my Acer, 2) I Pressed the connect button on the top center of the Cisco. I was done and have an Excellent connection. Good Luck, Jim.

I too have just encountered the wi-fi issue and looking for some help on resolving it.

I am running 3.1, Kernel version 2.6.36.3 and build Acer_A500_4.010.13_COM_GEN2.

I upgraded to 3.1 while back the the wireless working fine. I had not used to the tablet for a few days and when I took it today, the wi-fi was constantly trying obtain my IP address. When I try to connect the signal strength is at the maximum but then suddenly it drops to nothing (this is on the wifi networks screen). I turned the wi-fi analyzer and I seem to have good signal strength (around -44dBm).

I have tried the paper clip reset a number of times but to no avail. One thing I am noticing is at some point when I was not using, it has tried to update my apps, but was not able to and I see down arrow at 0% in the task bar, and I am not sure how to shut it down.

Any help is appreciated.

Do you use encrypting and if so did you check to make sure the paraphrase is correct?
Have you made sure airplane mode is off? Sorry I had to ask!

Yes to both. I also checked my wireless router logs, and for the tablets MAC address i see it getting connected then immediately after that I see "disconnected for reason: Received Deauthentication". I am using a Dlink DIR 655 router. I have also re started the router.

 

[splatoid]

Maybe you can set a DMZ for just the tablet and try to run through that.
My tablet and phone are OK but I'm having problems with my D link router. Seems to have quite poor signal. But not always. So I cant figure this thing out.
I have set it up many times. But that's another story.

Hi guys! This is my first post here so I just want to start by saying hi to you all.
I have a question about the a500 and wlan. I got the a500 last monday and the fist thing it said was that there was an update. So I downloaded it and then about 10 minutes later I relised that I only had one wlan bar and I was sitting about 3 m (10ft) from my wlan box. With in 10 min it lost connection two times. I went back to the store and they replaced it with a new one. I don't know if the first one I had, had a hardware problem or if it was the 3.1 software that I installed. The new one that I now have works very well but now I don't know if I should update it or not. What do you think? Is this wifi problem an "old" problem or do you still have it?! Just to make it clear I now have the a500 android 3.0 with no updates, and it is working fine! Thanks

 

[Graffen]

You do know that it is 3.2 now? There is a lot of improvements between 3.0 and 3.2.
I had never any problems with reception when I had 3.1 (I got the 3.2 a few days ago,and it's even better now).

Hi,

I am also new to this and I purchased an Acer Tab a500 two weeks ago and I have not been able to use it also. I have not been able to connect to my home and/or phone hot spot. This is very frustrating. Any suggestions. I am considering taking it back.

I had a problem with my Iconia Tab running android 3.1, where wifi would not connect. Acer put out a patch to fix this on their website. I had to download it on my computer and put to the root of an sd card to install the patch.
My wifi worked afterwards, but it required an sd card
