No access to Internet - Limited access for both wired and wireless

[sp33dyk]

Hi i am new here
My Original post is here - No access to Internet - Limited access for both wired and wireless - Microsoft Answers

I have seen most of the threads going un-answered so i feel that i can get help from here!

My HP Laptop:
WIndows 7 Professional 64bit
Intel Dual Core 2 Ghz
Ram - 3 GB
Atheros AR5007 802.11b/g WiFi Adapter
Yesterday i was working on my laptop and in background the AVG antivirus client was downloading the files.
I have Avira installed and had planned to uninstall it after AVG client would be done with toe download.
Suddenly i faced a blue screen and when i restarted Windows, the AVG setup was incomplete...i couldnt uninstall it...so i did system restore but i was given some kind of bad image/sector? error...i dont remember that exactly....
but the programs and features now didnt show any AVG installation.
i have gone through Windows troubleshooting steps and searched a bit on various forums but none helped.
I face this problem on wired network too.
the router seems fine, as now im connected on my desktop from the same router.
And i know how to install the drivers and all connection settings part.
-----------------------------------------------------------------------------------
Ok, i just formatted the system drive..
reinstalled Win 7 64 bit again and still i face the same problem!
I can access my router(with wire and wireless) but can't connect to internet
I also did router reset just to try in-case if it'd work...but it didnt

I just accessed wireless internet on another laptop!
So i am sure we need to do something with the laptop.
Thanks

Welcome to SF,

Have you tried connecting your laptop to another Wi-Fi network or hotspot or somebody else's router and do a wired connection?

How about a wired connection to your Modem? What's the outcome?

I don't normally work on HPs but when I rebuild most of the computers where I work, I usually have to download the adapter drivers and install them before I can connect to anything. (Using a USB stick and another computer)

I'm not sure what exactly happened to start all this, but since you reinstalled Windows, you might give it a try

Not yet...will be trying at a friends place/college.
And i have mentioned above that wired and wireless both don't connect to internet but just the router.
So for wired and wireless i face the same problem

I don't know if it will work, but i have installed 7 a couple of times and never had to install any drivers for Wired or Wireless LAN.
Though giving it a try is not a bad idea.

Thanks for quick response

Just, i searched my old DLink router, configured it and it worked with the laptop! It is a simple router with 1 LAN port.
So the router and my laptop aren't coordinating with eachother
My wireless router - DNA-A213(it was given by my ISP)

 

[seavixen32]

You've got two choices now.

Continue using your old Dlink router or pester your ISP to replace the faulty router they sent you.

If those two choices don't suit you could always go out and buy a new up-to-date router.

 

[sp33dyk]

I have already complained them about it.
But why does that happen? the laptop restarted and since then there is no access
+ that router is supporting Wireless internet on Acer laptop which has XP installed.

 

[seavixen32]

Have you tried resetting your ISP router's settings?

It sounds as though the router is faulty so your ISP should rectify it.

If they won't, ask for your MAC number and tell them you're going to switch to an ISP that has better backup.

Yes i did reset the router. And they WILL give me a new router/fix this one.

 

[seavixen32]

Just the job. Let's hope it cures your problem.

Yep, sounded like a faulty router. Please keep us posted.

I faced a new problem!
Yesterday i was working on my laptop with internet ON via my old wired router, and suddenly the LAN's LED light disappeared and i was disconnected. And in Network Connections(ncpa.cpl) i could not see that LAN. Also in device manager i could not see the driver associated with my ethernet LAN(Realtek RTL8102E/RTL8103E Family PCI-E Fast Ethernet NIC). Then i plugged out the cable and plugged in back but it didn't work. I had to restart the laptop...it didn't detect the connection till i manually installed the drivers back. But the configuration on Windows was retained back.
I don't know what's the matter
But it's sure thing that my WLAN router and laptop don't work with each other :/

EDIT: I think i got the reason for that! - Allow the computer to turn off this device to save power
Will see if the problem persists

Thanks

Oh this is ridiculous!
I can't figure out what's the problem!!!!!!!!!!
I disabled allow computer to turn off..... but still sometimes i get disconnected...either the device is un-detected or it shows Limited Access! ... and REPAIR the driver and that too doesn't work, then i restart windows.
So i can't figure out what's wrong....
Am really confused...
The ISP's sent their men at my house today for router replace, but no one was at home

Is this for both wired and wireless connections? I guess, you'll just have to wait for the ISP Tech to show up and please keep us posted.

Have you ever tried my suggestion in Post# 2? Connect to another Hotspot or Wi-Fi Networks? You've mentioned that you were going to give this a try, then I don't recall or seen an update.

 

[sp33dyk]

No i didn't get time to connect to 1 wireless spot
But the shocking stuff is i connected to internet today(with that router without any fix by ISP's)..in both wireless and wired!
I don't know what is/was wrong...i did some changes with network settings and others in Windows...
When i figure out the exact issue i will post it here so someone with similar problem will get help.

Still i face that wired connection problem...the driver goes missing anytime!

A question: Can Power Saver Plan cause all these problems? Though the Power Saver Plan had Max priority to Network Adapter, can it be the reason?

Thanks

If you are getting disconnected try to Disable the problematic network adapter's Power Saving Mode.

Yea i know...i did that before too but still it disappears..sometimes Scan for Hardware changes works and sometimes it doesn't, then i need to restart windows.

What AV or Security Software do you have running?

Let's try something else:

If you have Bonjour installed, please uninstall it.
Completly Uninstall and Remove Bonjour Service and Files (mDNSResponder.exe, mdnsNSP.dll) for Windows « Amarjeet Rai’s Blog

Install and run Malwarebytes:
Malwarebytes Anti-Malware - Free software downloads and software reviews - CNET Download.com

Click on Start and type msconfig, locate the Start up and Services Tab, disable any Apps and Services that are unnecessary to run.

Run sfc/ scannow:
http://www.sevenforums.com/tutorials/1538-sfc-scannow-command-system-file-checker.html

If none of the above helps, you might want to consider a restore to factory default of your laptop, try a different Network Adapter or a Clean O/S install....don't know what else to suggest.

 

[sp33dyk]

executed sfc /scannow ... and will remove bonjour later...
And yea, Malwarebytes has been with me since 2 years
Tomorrow, will let you know if i still face any problems.

Thanks
