I have a samsung galaxy chat B5330 device.

Whenever I try to connect it to wifi, I get various errors as follows,

  1. Using DHCP :- Here it shows a "obtaining IP address" message but never connects.

  2. Using Static IP :- It connects to wifi but then shows a "internet not available" error. I'm sure that internet is available as many others use it successfully using other android devices/laptops etc.

EDIT:
I found out that not all are able to use the wifi. Some do not get connected(stuck in "obtaining ip address"), some get the "internet not available" error, some connect and get internet but at very slow speeds(10 KBps download speed) while some lucky dudes get blazing speed(10MBps download speed)

Could this occur due to to many signals at same place? At any given place in campus, we get at least 2 strong and 1/2 weak wifi signals, not to mention some secured portable wifi hotspots from androids.

How do I solve this error.

Note that I don't own the router/wifi, it's open(No security, accessible by any student.)

  • Could that be a MAC filter on the routers end? Doubtful (if anybody else can connect fine with any device, even new ones which never had connected to it), but the first thing coming to mind.

  • @Izzy Could this be due to too many routers? There are 1 to 3 routers at every floor, so we always get at least 4 signals at any time(few from same floor and few from above and/or below).

  • I don't think so (or I would have the same trouble here, with always ~10 APs in reach). I'd rather say it depends on which AP the device tries to connect to, one of them might be the culprit. But that's rather not an Android specific question I bet. It better fits the "personal and home computer networking" topic covered by Super User – as long as it's not "specific to corporate IT support and networks" (off-topic there).

Seems DHCP is not enabled on WIFI router, you may need to ask others to obtain DNS address, to connect to internet, DNS info is required as well
