Wifi Acces from Android Tablet

I have just received a new Lenovo Thinkpad Android Tablet and am having issues with wireless access from it while at work.

The wireless access point is identical to what I have running at home where wireless is working from the Tablet.  The main difference between the two setups is that at home the wireless access point is also my DHCP server but at work it is not.  

Setting a static IP address at work does not resolve the issue.  I installed an app where i can perform a ping from the tablet and I get a "Destination is Unreachable" returned.

I have resolved this by setting up a new wireless unit.  The time to do this was more cost effective than pursuing resolving this issue.

Any chance they are using mac address filtering on the wifi?  Usually mac filtering would cause a client to not even establish a connection but I've seen some implementations where they will associate with the network but will not pass traffic.

Other than that, no clue and look forward to other experts ideas.

They could Have all sorts of stuff at work to not allow your tablet. Best thing would be to ask the network admin

MAC filtering is not taking place.  I can connect other devices such as iPhones, iPads, and Windows mobile devices without issue along with standard laptops.  I have no other Android based devices from which I can test.

I am the network admin and have not set anything up to deny devices connecting.

I agree with aaron, sounds like you work at a small company so chatting with the Admin shouldn't be very hard.

Well if your the admin then let's run through a few things.
Is the ip you gave conflicting?
What is the security setup? Wpa tkip or wpa2 aes? Mucin those is bad.
2.4 or 5ghz? If both then try the other.
What type of access point?
Radius?

I would prefer not to use a static IP but as the DHCP adress is not being handed out I thought I would try it.  The static address is not conflicting.  It is in a range that is outside the DHCP range and not within the range we use normally for static IP's. I have run a scan across out network and confirmed the static IP address is not being used.

The wireless access point is a Netgear DG834G.  it is set to use WPA-PSK (TKIP) using b & g mode.  Same device at home with the same settings apart from SSID and preshared key. The device at home works without issue.

The wireless settings on the tablet show as 'connected' but also 'acquiring address'.  The DHCP server is running Server 2003 and is also out DNS server.  The gateway server is a different address.

Can you turn off b? That slows stuff down, and can cause problems.

Does your key or SSID have spaces in it?  I know this sounds stupid but I've had an issue with a Motorola Droid 2 that would do some strange things until I removed the spaces in the wireless key and SSID.

No spaces in either the SSID or key.

Special characters?  I know this is venturing a little far but I've experienced an iPhone issue with a Linksys (E2000 I think?) with a ! in the key.  I have no real knowledge on this subject, just weird experiences... :)

Hopefully I'm not leading this in the wrong direction.

One more thought.  Are the firmware versions of your home and office devices the same?

iandjourdainAuthor Commented:
I would expect them to be the same as they were purchased from the same supplier at the same time and I have not performed any upgrades to either.

The key is a series of numbers and letters, no other characters.

Do you have any other tablets or Android Phones you can compare. If they all connect and the new tablet doesn't, its probably something with the tablet and not the wireless.

What I would do in your case is possibly create another SSID with open authentication and see if it works..

I just got a coleague who has an Android phone to test and his device is hunting for an IP address as well.  The phone is using Android 2.2.

Is it WPA/WPA2 mixed or just WPA?

iandjourdainAuthor Commented:
WPA only.

Kenmcse1969Commented:
Just off chance, have you looked at the firmware to see if there is an update? There is a possibility that the version and the WPA setup is having compatibility issues with the Androids.

Have you tested with an Open test SSID to be certain it is your security settings.

Sometimes there's no way around it and new hardware is the answer.  Thanks for letting us know.
