Wi-Fi connected, no internet access. Other devices work

Hello,

I have moved into a new apartment and my laptop connects to the wi-fi network but there is no internet access. The apartment is on a school if that makes a difference, I'm not using a home router. My Mac, tablet, phone etc all connect to the same network without any issues. The connection to the network works fine via an ethernet cable but I no longer have access to the port to connect this way.

I have tried going to cmd prompt to type:
"ipconfig/release" and then "ipconfig/renew" to no avail.

I have also tried the following commands with no resolution to the problem:
ipconfig/flushdns
nbtstat -R
nbtstat -RR
netsh int ip reset c:\resetlog.txt
netsh winsock reset

I have uninstalled my third-party firewall and tried selective start-up and no dice there either. I have also made sure that the IP and DNS address are obtained automatically.

Anything I can post here so someone can identify the problem please?

Thanks

can you connect by cable and post the ipconfig /all - just to check the ipconfig /all when it is actually working

Thanks for your help.

Sorry but I can't post ipconfig/all when connected via ethernet as the ethernet port has been blocked/turned off (long story) so I can not get access via ethernet cable either.

I copied and pasted that command prompt: echo > 0 & PING 172.16.40.1>> 0 & PING 46.228.47.115 >> 0 & PING google.com >> 0 & tracert google.com >> 0 & echo [/php] >> 0 & notepad 0

But I am not getting anything after pressing Enter, just the text above stays on screen with the cursor flashing beneath it?

For your information only
these tests will check various stages of the connection, the first ping test, ping default gateway checks to see if you still have a connection to the router.
The next two Ping google.com & Ping 209.183.226.152 tests the connection to internet. google is to test by name and the ping test using a number is checking that a connection exists without DNS.
these tests then confirm if there is a dns issue on the connection.


if you see on the results a
"general Failure"
PING: transmit failed. General failure.
This sometimes means a firewall issue
What firewall / security suite or anti-virus do you currently have on the PC - or you have ever had on the PC in the past - any trial ware - like Norton, kaspersky or Mcafee or any free security suites like zonealarm, AVG , Webroot etc

Oh man, that is the exact driver and site I used to update the wireless on the laptop! And obviously no luck.

This connectivity issue is bizarre. Normally I can solve what's up after a couple days but this is something else. For what it's worth, here's some more info that may be useful to someone: when I try to load a page, it times out and error message in Chrome is Unable to connect to the proxy server.

Weirdly, the laptop did have some kind of wireless connection earlier (before I made my first post on here) after I flushed several settings in CMD and used CCleaner to clear temp files and fix registry issues. I was able to load one web-page but since then, there's been no connection.

Dunno, seems unlikely but perhaps the school is using a newer wireless standard and my 2012 laptop doesn't get a good connection through it? All the devices that work are from 2014 onwards.
 
#22 ·
It may be time to find out the backstory as to why you are not allowed to use wired. It may play a part in this.
 
#23 ·
Probably a good idea. I remember I was using wired connection no problem with the problematic laptop and also another desktop. I come home from work the next day and no wired connection is even detected from LAN port. My girlfriend says this is because the school disabled unauthorised connections via ethernet cable as they don't want the school's students (not including us adults - my gf is a teacher here) connecting via ethernet.

However, even before this, my laptop couldn't connect wirelessly. Everything else did and still does - two phones and a MacBook.

I'm going to get her to talk to the tech guy here but from previous experience the guy can treat you a little like a simpleton with basic advice. But bless him he probably gets bombarded with a lot of really easily solvable issues. I'll definitely post my updates from these steps tomorrow.
 
#25 ·
IMHO, (and Terrynet and etaf have forgotten more networking than i will ever learn) the 'disabled unauthorised access' part most likely is playing a part in this. I will defer to them, obviously, but I would start there.
