Can't connect to internet or LAN over WiFi

All worked fine, until I rebooted the system. The wifi is detected, and on. But I can't connect neither to internet, nor to the LAN.

1) I tried to turn wifi off/on, and it successfully detects the wifi network, and state the status as "Connected". The wifi icon in the status bar is shown, but is always gray. I also have an application called "Wifi Analyser" and it detects 2 networks (mine, and some foreign one). Both are ok and have strong signal.

2) Connection settings
Status: Connected
Security: WPA/WPA2 PSK
Signal strength: Excellent
Link speed: 2MBps
Proxy settings: None
IP Settings: Static
IP Address: 192.168.1.128
Gateway: 192.168.1.1
Network prefix length: 24
DNS 1: <internet provider dns # 1 goes here>
DNS 2: <internet provider dns # 2 goes here>

I tried to open web pages and failed. I also tried to open my router page at 192.168.1.1, and it does not open. In both cases the browser said: "Webpage not available ..." Notice, that I can open 192.168.1.1 from desktop, and I was able to do this from my device in the past. Also, I have ES File Explorer, that now can't connect to LAN resources.

I tried to ping device from desktop PC, and here the results:

Pinging 192.168.1.128 with 32 bytes of data:

Request timed out.
Request timed out.

Request timed out.

Ping statistics for 192.168.1.128:
Packets: Sent = 4, Received = 0, Lost = 4 (100% loss),


3) About device

Model number: Transformer TF101
Android Version: 3.2.1
Build Number: HTK75.WW_epad-8.6.5.13-20110925
Wi-Fi version: V5.2.63
Kernel Version: 2.6.36.3 (android@Mercury #1)
MobileDock version: EP101-0213


4) Reboot...
4.1) I tried to reboot it few times
4.2) Did factory reset (Privacy > Personal data > Factory data reset)
4.3) Did the "Cold boot"

No luck, wifi detected, I can authenticate, but no internet or LAN connectivity.

Any idea how to diagnose and recover from the issue?

Great and very complete explanation but I didn't see that you tried restarting the router.

Oh... That was that simple!!! I powered off/on the wifi router, and it connected. Thank you, @leeshor!

Rebooting the router is always my first choice.. We thank you Lee.. Job well done.

Welcome to the forum!

Looks like lee got you all squared away.

I will say I was quite impressed with the level of detail that you sent in.

Sometimes it is the simple stuff that we overlook. I once had a room mate in college that could not get his speakers to work. He went through everything trying to figure it out (even reinstalled drivers, removed and reinstalled the card) and the issue was the speakers were plugged into the microphone input. :disappointed:

Any other issues, let us know and we will get you back up in running in a jiffy!

An amazing amount of troubleshooting info you have got there!

But two points struck me:

1. How did you manage to get all that information? Especially the Connection Settings you are mentioning there.

2. You are saying IP Setting: Static - you mean you have fixed the IP address for the device - but I thought the device had DHCP by default. Just out of curiosity how did you fix the IP address?

Have you rooted your TF?

Number 1 - I have an app called Network Signal Info that can give all of that information

Number 2 - If you long press on the WiFi Network in Settings, you can choose Modify settings and change from DHCP to STATIC. This was a workaround for some routers that the TF would not obtain an IP address on some older stock firmware.

No need to be rooted.

The signal level was aquired with "Wifi Analyser"

The details about connection and static IP setup: Settings > Wireless & networks > Wi-Fi networks > Long-press on some connection > Modify network.

Hmm...I can't get to it!

Nothing seems to happen when I long press on any of - 'WiFi' or 'Wi-Fi settings' options that I have under Wireless & networks.

When I press 'Wi-Fi Settings' - I get toggle options to disconnect from the network or connect it back and another one for Network Notification - toggle. Nothing to set it to DHCP or Static - mine seems to be always DHCP. I also see an Advanced option which shows me the IP address and MAC address in use by the device - but still nothing to set static IP address.

I do have rooted my TF and am using a customised ROM - and this may be the result of the customisation the ROM author had done.

Brings up the next issue - on this forum we have lots of users who may be running custom ROMs for whom some of the option settings within the 'Settings' option may be different.

Oh dear! A support engineer's nightmare!

[EDIT]
Ooops! Spoke too soon - as per alex2k8 I need to long press on connection and then select Modify Network from the menu that pops up - and I do see the option to change to Static IP.
Thanks Alex!

I got connected to WiFi but can't get on the internet. I peep getting Webpage not available. I do not have this problem with my HTC Thunderbolt.
