[SOLVED] All web browsers suddenly very slow

Wayne Bruce · 07-20-2012, 08:40 AM

Hi folks, I'd be extremely grateful for any help with this issue...

My Lenovo laptop is only 2 weeks old and was working fine until yesterday. Now all my web browsers (i.e. chrome & firefox) load web pages extremely slowly, or not at all, or occasionally I'm getting 'Error 101 - Connection was reset', or 'Error 105 - unable to resolve the server's DNS address'. Google searching brings up a results page quite fast although it takes a long time to fully load, but clicking on any link is when the real slowness starts.

It's not a problem with my wifi signal, the laptop is connected to a strong signal, and all other wifi devices like my PC are flying along on the internet nicely.

I've restored to a previous point when everything was fine, but the problem persists.

I've got McAfee, no problems there. Malwarebytes full scan no problem. Used CCleaner to clean eveything up & fix registrys. Plenty of memory space.

I've tried booting up in safe mode with networking, the problem persists.

It's a lenovo klaptop running window 7 home premium, SP1, MMD E-450 APU, 4GB, 64-bit Operating system

Hi and Welcome to TSF!

Please do not run any registry cleaners, even CCleaner's as it can cause harm to your computer.

If the computer stays on does it even lose Internet connection? How long does your computer go without losing internet connection? Are you WiFi or LAN?

Wayne Bruce · 07-20-2012, 09:14 AM

I'm on WiFi & the internet stay connected, no dropping out.

Does the problem happen on IE? Any redirects?

Is the connection drop on all websites?

Wayne Bruce · 07-20-2012, 09:37 AM

IE is slow as well, maybe a little faster than chrome/firefox.
Connection drop on all websites.

Wayne Bruce · 07-20-2012, 10:43 AM

I don't think there are any redirects happening.

Try running this Microsoft Fixit here:

Diagnose and fix Windows Firewall service problems automatically

Wayne Bruce · 07-20-2012, 01:27 PM

I ran Fixit. Which found no problems.

I had to make Microsoft Windows the firewall operator, so I uninstalled McAfee, which was probably a bad idea I guess. I'm installing AVG free for antivirus/spyware protection.

The problem remains the same, a random page loads slowly. Just tried facebook twice - got a error 101, then error 105. Tried twitter - error 105.

Thanks for all your replies Masterchief

Do you have any others devices connected, and are they having the same problem?

Wayne Bruce · 07-20-2012, 02:19 PM

Hi AJZnSD.

There are a few other devices on the network that are all working well and fast.

AJZnSD · 07-20-2012, 02:28 PM

Hhhmmmm, any chance you could test out the laptop with a wired connection? I would be interested to see if you have the same problem wired.

Wayne Bruce · 07-20-2012, 02:42 PM

I just tested it out with a wired connection and it worked great. So it must be some kind of wifi related thing, right?

AJZnSD · 07-20-2012, 02:46 PM

That would be my guess. I would check to see if there are updated drivers for your wi-fi card. Here is a link to Lenovo drive site http://support.lenovo.com/en_US/downloads/default.page. If updating the drivers doesn’t help let me know.

**Tomken15** · 07-20-2012, 02:55 PM

At the cmd prompt enter these cmds :-

netsh winsock reset catalog > Enter
netsh int ip reset reset.log > Enter
exit > Enter

Reboot when exited the cmd prompt.

**Tomken15** · 07-20-2012, 03:26 PM

Forgot to add that you'll need to run these cmds as an Administrator (probably because that's how I always run it

)

Wayne Bruce · 07-20-2012, 03:51 PM

Tomken - i did the cmd, which seemed to fix the problem for a minute, a few pages loaded fast, but it has become very slow again, and some pages are bring up error messages, i've had an error 7 and a error 105.
-And it just happened again, it's worked for a minute or two, but now it's slow and coming up with 'Error 105's again

AJZnSD- on the site it says the relevant wireless was last updated in February. So I'd guess my drivers up to date. Should I still download and install the driver?

**Tomken15** · 07-20-2012, 04:17 PM

Can you post a shot of the error 7 message as this could relate to a memory problem.

Wayne Bruce · 07-20-2012, 04:28 PM

I can't really post a shot because 'Error 7' only came up once. Right now it's 'Error 105 - unable to resolve server's DNS addres' that's coming up.

I used the Window network troubleshooter, which says it can't fix 2 problems:
-the comnection between your access point, router, or cable modem and the internet is broken.
-the default gateway is not available

**Tomken15** · 07-20-2012, 04:34 PM

May have been thinking about something else with that last post.

Follow these steps to repair .NET Framework 4.0 Windows 7 - .Net Framework version 4 needs to be repaired - Microsoft Answers to see if that resolves.

EDIT Wire up and enter these cmds (as Admin) from the cmd prompt :-

ipconfig /flushdns > Enter
ipconfig /release > Enter
ipconfig /renew > Enter

Noting the space before the forward slash.

Wayne Bruce · 07-20-2012, 05:25 PM

I repaired the .net framework stuff and ran the ipconfig prompts but nothing's changed.
