Hi guys, I've been experiencing some internet access problems. From time to time (quite regularly actually) I will suffer from severe internet slowdown or more often complete loss of internet access. I have broadband, use a wi-fi connection and share internet access with other flatmates. Initially, I thought the problem was because of peak time access, or my flat mates were hogging the bandwidth but I've found that his problem has reared it's ugly head when it's midday and they're not here. Plus, it seems that I am the only one experiencing this issue, when it happens to me they are having no issues at all.

 

Looking into this problem, I thought it was initially because my IPv6 read 'No Internet Access' while my IPv4 was working fine. But after a bit more reading it seems that I needn't be concerned about IPv6. 

 

Things I have read and tried:

 

  • Multiple restarts on the router (hard and soft)
  • Disconnect and reconnect on my laptop
  • Using the Windows diagnose issue (does occasionally work - screenshots of when it doesn't below)
  • Uninstalled Bonjour
  • McAfee AV issue (I have removed all traces of this now)
  • Changed the TCP/IPv4 properties to obtain DNS server address automatically
  • Having a fixed IP address rather than obtain automatically 

 

The following commands in cmd:

 

  1. netsh winsock catalog reset - netsh int ipv6 reset reset.log
  2. /f route
  3. ipconfig /release - ipconfig /renew (screenshots of what I get below) 

I have a feeling this might be revealing the route cause, but I don't know what that is:

ipconfig /renew screeny

I would very much appreciate any and all help with this thanks!

Have you tried connecting to the router via Ethernet.?

Agree - try Ethernet.

 

Assuming Ethernet works, update/download a wifi driver refresh.

Ethernet works perfect, unfortunately I can't use it all the time. I am looking into the wifi driver refresh - I have a few it seems? Intel, Dell, a couple of MS Virtual ones and a Realtek one. Do they all need to be updated?

At this point it would be nice to know the make and model of this computer.

 

If this is a desktop you are most likely using a sub wifi adapter.  If this is the case go into the Device Manager and double click on Network Adapters and see if there is a yellow warning icon or red error icon.

 

See what the driver is in the Network Adapters and download it online.  Then uninstall the driver in the Device Manager, now install the downloaded driver.

I have a Dell XPS L502X - 2011 from what I was told by the Dell check.

 

I have updated just the Intel driver so far and there 'may' be a slight improvement. When my connection goes to crap, it still runs albeit very slowly. Will need to do more testing.

Go to this Dell website page.

 

Click on Network to open the downloads available.

 

Click on Download for the Intel Centrino Wireless-N 1030/Advanced-N 6230 Driver.

Thanks. I guess I should make sure the rest of my Network devices are updated with the latest drivers as well?

You initially posted that the problem was with the wifi connection.  This being the case I would install just that driver and see how it goes from there.

 

I was out of town yesterday, I apologize for not being able to get back to you sooner.

No problem. Still having some serious slow down issues at times. I'm going to check again and when it happens see how my tablet fares with the connection because this is just crazy.

I did indeed. I even used Intel's Driver Updater to make sure I got the right one.

I posted the link to Dell's download for that driver.  That is where you should have downloaded the driver.  You always want to use the manufacturer's site to download drivers.  The exception is if the device you are looking for a driver was not installed at the factory.  Like a dedicated graphics card.

I see, my apologies. I did look at the site, but my hardware was a bit different to what was listed - I have a Intel Wirelss Centrino N-1000 whereas on Dell it lists Intel Centrino Wireless-N 1030 so that's why I thought maybe it was best to get the the exact driver from Intel. Should I go ahead and get this one instead?

I see...  It would have been helpful to have mentioned the fact that you had made this change.

 

Try the driver for the N-1000.
