Reinstalled Wifi driver and now internet is really slow

Hello, I have an Acer 5755G Laptop (Windows 7) and one day, I couldn't detect any internet. But I fixed that, I just had to download a "Network Controller" driver. And I fixed it, now I can detect any wireless network. But now, the problem is my internet connection is really bad (only on this computer, my brother's internet works fine.). And in video games, one of the reasons internet is so important to me, I'm having 300-900 ping! Please help! If you have an answer give it please. If you don't..... well I'll just buy a new laptop

Thanks, Tib

 

Hi tib,
Please don't go and buy a new laptop
Try a different driver, sometimes older driver perform better than the newer ones, flush dns, Try system restore or if you have backup, recover from that.
3 Ways to Flush DNS - wikiHow

 

Thanks! I'll try it out.

 

More details needed here. What is the Wi-Fi card you're using? What driver version do you have installed? What is the connection speed for Wi-Fi as reported by Windows?

Also I moved this thread to networking as it seems to be more network-related than an Acer problem.

 

I can't really find an updated version of my Network controller "Qualcomm Atheros AR5B97 Wireless Network Adapter"... and I'm not sure what flush dns is...

I don't know if this helps knowing what wifi card I'm using but in the device manager under network adapters it is Qualcomm Atheros AR5B97 Wireless Network Adapter. In its properties the version is 10.0.0.274

As for the connection speed the ping is 388 ms
Download speed: 4.61mbps
Upload speed: 0.30mbps

 

Open cmd ( right click cmd select" Run As Admin"), type ipconfig /flushdns press enter. flushing dns clears the broken links.
Please provide more info as requested by downloads, in the mean time, here's a link for drivers:
Drivers for Atheros AR5B97 and Windows 7

EDIT: I have this driver in my 5750 and works fine, give it a try: http://drivers.softpedia.com/get/NE...os-WLAN-Driver-910334-for-Windows-7-x64.shtml

 

Please provide more information about the information I need to tell you guys.

I did the flush thing didnt really change anything :\

Hi umm, you know the download links? Yeah where do I put the files from the .zip? ( Sorry I'm quite a newbie)


Thanks, tib

 

You need to tell us about the Operating system (Windows 7,8,8.1 etc), what type of Router model.
Have you tried different drivers?

 

Windows 7
router: netgear DGN2200v3
Also look at my last post. Where do I put all the files the .zip gives me?

 

I wouldn't recommend roiling back to old driver for security reasons.

Here's the most recent driver I know of - 10.0.0.288 (you have to click on Télécharger to download)

The download is unreasonably big due to the fact that Bluetooth suite is also included so don't be surprised (239MB)

Extract the archive, and double click on "setup" and follow instructions from there.

 

Didn't help. At all. I wonder what could be the problem.

I'm guessing it's not about the driver, then?

 

What is the connection speed reported by Windows? Check Networking and Sharing Center (or whatever it's called) and click on the name of the connection.
It will show connection speed i.e. 150mbps or 300mbps.

Also is the connection strength OK? (those bars in the tray)

 

3/5 bars
144mbps

 

That's not bad. Do you have 3 bars right next to the router or at a certain distance?
Please make sure to reset the router and a modem too.

 

I have 3 bars from a distance. resetting the router doesn't help. And as I said the bad internet is only happening on my computer so I'm pretty sure it's something with my cmoputer

 

Yeah I know but I'm trying to eliminate potential issues.
Can you please run the same tests while connected to the router via an Ethernet cable? It's also (remotely) possible that it's not a driver or Wi-Fi issue but a software issue which would affect not only Wi-Fi but also Ethernet.

 

With ethernet cable:

[Windows center of stuff:
100mbps

speedtest.net:
384ms ping
download speed: 2.83mbps
upload speed: 0.30]

[I decided to do a test when I'm right next to it too, here are the results.
5/5 bars
144mbps]

 

try to disable all your power saving for the wifi, or just simply test it with 'high performance' profile, and connected to mains ac adapter.

 

As I'm not an expert in Networking, it would be much appreciated if you could tell my how to do those things.


EDIT: Umm it seems it has been fixed by itself? Maybe it just needed time. I will post again if it happens again

 

Nevermind. I didn't fix it only lessened I guess.

 

@Tib

Your benchmarks made while using Wi-Fi is pretty much the same as the one made with an Ethernet cable connected.
That pretty much rules out Wi-Fi as the culprit.

It's either something on your computer (AV software, firewall a virus/trojan, P2P app working etc) or it's a ISP/network issue.
Can you double-check bandwidth on your brother's computer to make sure that it's not the latter?

 

Huh on his from speedtest.net

Ping: 40ms
Download speed: 5.14mbps
Upload speed: 0.40mbps

Windows center thing:

86mbps

0.o and yet its better.

 

I think it might be fixed actually...

Now getting minimum 50 ping in video games

 

It cannot fox itself. There's clearly something wrong and I'm expecting another post from you that it's not working properly yet again

 

Hah I guess you were right. It's back to before. (High Ping)

Maybe I have some information you might want to know. On the speedtest.net, yesterday, when it worked, it detected me where I was (Italy, though I'm not Italian) and when it doesn't work (high ping) it says I'm in another country.

 

As a moderator I can see IPs that were used to make each post. I took a liberty of looking at the IPs you have used in this thread and apart from the Italian one there are at least 5 other IPs from two countries.

These are most likely anonymous proxys. When you're getting straight through to a website it's much quicker but when you are getting through a proxy it's slower hence the ping goes up.
I don't know if you have installed any proxy/VPN software or browser add-ons but that's the culprit.

If you're not Italian, yet are living in Italy, maybe you needed to use proxy to get access to some content that is only available in your country of origin?

 

Sorry if this is getting annoying but I need instructions. I'm not very good at these things. But you say it might be browser addons?

EDIT: Just cleaned up my addons using avast. Nothing changed

EDIT: Oh nevermind I don't really need instructions if I understand correctly. You're saying that there is software or an add-on that is affecting my proxy/VPN?

AND YET ANOTHER EDIT: Oh actualy I guess I need instructions, how would I find this software/add-on?

 

So you mean I need to go to configure the proxy server, go to LAN settings and enable it? 'Cause that's already checked.


EDIT: Currently it says I'm in LONDON, and it says my IP is 198.47.115.135, which it is not.
EDIT: Huh. on every site I go to it says that's my IP.... before it wasn't. That is the problem! (Which may be what you said , I don't know....)

 

No, you need to disable proxy if you have one enabled. Or figure out if you have a VPN or proxy software installed.

 

Ok I disabled. So it means there is software installed.

 

Thank you sooooooo much. It was this program called Hotspot Shield! so happy.
