Red cross/Busy Blue circle sign on prefect working internet connection

Respected Sir,
Sevenforums,

HARDWARE- I have Win 7,Home Premium,64bit,Dell Inspiron 15R N5010.
My network adapters are: Realtek PCIe FE Family controller & DW1501 Wireless-N WLAN Half miniport adapter.
My ADSL modem + WIFI router is Netgear DGN2200v3 latest version of firmware v1.1.00.10_1.001.

PROBLEM- My network connection icon in task bar shows Red cross disconnected or revolving Blue Busy circle network on wired and wireless connection. But my internet connection works perfectly fine. Please suggest solution to enable network notification correctly. I will carry out every possible advise to enable correct network notification. Problem arise when I personally fiddled with router's security option like changing WPA2-PSK[AES] to WPA-PSK[TKIP] + WPA2-PSK[AES] and again back.
Right now is WPA-PSK[TKIP] + WPA2-PSK[AES]. I have connected my laptop to internet via LAN cable.

My Netgear DGN2200v3 provides WEP, WPA-PSK[TKIP], WPA2-PSK[AES], WPA-PSK[TKIP] + WPA2-PSK[AES], WPA/WPA2 Enterprise. Also please tell which type of network security option should I keep to avoid further conflict. So which should I choose?

I also have posted this issue in Microsoft community but didn't got expected reply nor solution, Please check this link about what Microsoft community answered:
Red X or Blue busy circle symbol on system tray connection icon even - Microsoft Community

I request Sevenforums to please clear my doubts and guide me till problem solves.
Thank you. :)

I read through the posts on the Microsoft Community page.

I would like to add more of the events regarding above issue.
Today morning when I ran sfc/scannow program again I got following message-
Windows Resource Protection found corrupt files but was unable to fix some of them. Details are included in the CBS.Log windir\Logs\CBS\CBS.logs


But again same problem arised that after typing findstr /c:"[SR]" %windir%\Logs\CBS\CBS.log >"%userprofile%\Desktop\sfcdetails.txt" I got 0 bytes file on desktop and original CBS.log file was of 4.42 mb .


From my layman point of view their is some thing wrong with my Windows OS and I want to repair it without crashing my system or re-installing Win7. Also I want to tell that recently before getting wifi broadband connection I had deleted my old restore points, disabled hibernation, disable pagefile.sys because on C drive had only 2 gb free space. After deleting them, I ran CCleaner & removed junk files,many unused programs, update my old software with 2013 versions. Then I ran disc check, defragmentation, completing this I installed Netgear genie software to control my newly establish wifi broadband connection. Then I created system restore point, at that time this Red cross or Busy blue circle was not issue. It occur when I personally decided to choose WPA-PSK[TKIP] + WPA2-PSK[AES] from WPA2-PSK[AES] (which was default set my bsnl network technician) security option to ensure good safety measure, even after changing it networking icons were working perfectly good. But problem occur when I switch back with WPA2-PSK[TKIP] and some other setting were tamper by me. Now I want to my networking icons to function normally with optimum security measure for my wifi.
I request you to guide my out of this problem.
Thank you.

I must advise you to never use a 3rd party application for WiFi connection management. There are security risks, and Windows 7 does a great job of handling these things itself. Disabling/uninstalling that would be my first suggestion. The next point of interest is the output you received from running "sfc.exe /scannow". If you have a Windows 7 install disc, boot from that and run the System File Checker with your Windows install offline. You can type "sfc.exe /?" to get the proper syntax. It should be something like:

Code:

sfc.exe /scannow /OFFWINDIR=C:\Windows /OFFBOOTDIR=C:\

Also, there is nothing to be gained from using anything other than straight WPA or WPA2 (unless you want to go enterprise and set up a RADIUS server, but that's a project in itself), so if you think that change coincided with when you started experiencing this problem, I would switch back to whatever WPA setup was working for you before. I might get some bad feedback on this one, but from an attacker's perspective, it would be just as hard to crack your WPA2 TKIP+AES pre-shared key as it would be to crack your WPA key. The method of attack is exactly the same; they would have to capture the 4-way handshake intact, and do endless Pairwise Master Key computations, and likely end up getting nowhere. Go WPA2 with AES if you like, since the only people to break AES (AFAIK) is the NSA. But then, I haven't heard of anyone breaking TKIP or CCMP. Anyhow, as long as you're not WEPing, you're golden.

I do not belong from technical background so please explain in complete layman style.

I'm sorry, I will try harder to explain myself more clearly

I have uninstall wifi management software like WeFi4.0,InSSIDer,Xirrus WiFi Inspector,Hotspot shield.

I am not familiar with some of those. Programs like InSSIDer are okay, but for the purpose of identifying the problem, you should not have any of these running, so that it will be easier to determine the cause of the problem. Make sure you disable/close completely all WiFi programs for the time being. As for Netgear Genie, I would suggest you exit that completely as well. I know that Netgear Genie has features that may be useful, but if you use it for connecting to wireless networks, it could be the cause of the problem. You should let Windows handle that. If I were you, I would uninstall it. WiFi connection programs are unsafe in my opinion - they can be a security risk. As far as I know, the built-in Windows wireless connection program has no known vulnerabilities, so it is the safest to use. Just disabling/closing Netgear Genie may fix the icon problem, as I have seen this icon problem fixed on other machines by removing wireless connection softwares.

Type "msconfig" in the start menu and hit enter. Under the "Startup" tab, make sure none of these WiFi programs are starting up and running hidden in the background.

You can also log in to your router directly by typing its IP address in the navigation bar on your web browser. You can find this IP address by first connecting to the Internet, opening up a command prompt (Start, Run, cmd, Enter), and typing "ipconfig /all". Your router's IP address is the entry that is labeled "Default Gateway".

"All that I want is to get working symbols of internet connection icon in taskbar. Not RED CROSS on network."
Now I have kept only WPA2-PSK[AES] security option, not WPA-PSK[TKIP] + WPA2-PSK[AES].
But does choosing any of above security option interferes with network icon representation in task bar?

No, the security setting shouldn't be an issue, as Windows 7 supports all of these options. Still, because the problem started right after you made the change, it is best to change it back to see whether or not its relevant.

Make sure you have Internet Connection sharing disabled (Network and Sharing > Change Adapter Settings > Right-click Adapter > Properties > Sharing), and also make sure that none of your adapters are bridged (Right-click adapter, the menu will say Add to Bridge or Remove from Bridge). Also, try running CCleaner and checking the tick box for the Tray Notifications Cache under the Windows tab. Many people are reporting that this problem is caused by wireless driver updates or other wireless utilities. If you've updated your drivers recently, try rolling back the driver to the last one that worked (Device Manager > Network Adapters > Right-Click wireless adapter > Properties > Driver > Roll back driver).

Also, Brink has some good suggestions on a similar thread:
Red X in network icon
To quote the man himself:

Double check to see if you have the Network Connections, Network List Service, Network Location Awareness, and Network Store Interface Service Services set to Started and Automatic.

Go to Start Menu, type in Services, hit Enter.

Assuming you have performed the sfc.exe operation, either from a Windows 7 install disc, or from within Windows, I'm betting it's no fault of Windows. You can boot in "Safe Mode with Networking" to confirm. Reboot and hit F8 repeatedly during startup to catch the menu.

When booted Win 7 Home Premium setup CD, I choose Repair>CMD> then I ran command as you said sfc.exe /scannow /OFFWINDIR=C:\Windows /OFFBOOTDIR=C:\ nothing came then sfc.exe /scannow /OFFWINDIR=D:\Windows /OFFBOOTDIR=D:\ (D its drive according to Windows 7 setup where windows files are stored) still nothing came.

The default drive letter for a Windows install is C. If your Windows 7 is installed to the D drive, you will want to use that in the command instead of C. I probably should have been more clear.

Also I am confused over command:-
sfc /SCANNOW /OFFBOOTDIR=c:\ /OFFWINDIR=c:\windows
and
sfc.exe /scannow /OFFWINDIR=C:\Windows /OFFBOOTDIR=C:\

When you run this command from your Windows install, you only need to use "sfc /scannow", but since you were getting error messages, we had to boot from the Windows install disc to run the command (this way your Windows install was not being used while it was being scanned, hopefully to get around the error message). The reason the command has to be entered differently in this case, is that when you boot from the Windows install disc, your 'working directory' is the X drive (created temporarily by the install disc). Because of this, it requires us to tell it the drive letter and location of the Windows install that we want to scan. This is likely why you weren't able to run "sfc /scannnow" without the extra file paths while you were working from the install CD.

Disappointingly "Safe Mode with Networking" neither showed the correct network status!

Hmm!
I am sorry to tell you this sir, but considering that, it would seem that the corrupt files in your Windows install found by sfc.exe may very well be the cause of this icon issue (but whether it's the cause or not, it is something you should take care of as soon as possible). I know that reinstalling may seem like too much to fix such a small issue, and I agree, but I would be very worried about corrupt system files (especially when sfc.exe can not repair them).

Before any of that though, please attach a copy of the "CBS.log" file that sfc.exe created. That will likely hold some interesting information, which could point to a fix which would not require you to do something as extreme as a reinstall of Windows.

I think you need to put the OFFWINDIR before the OFFBOOTDIR, but don't worry about entering it wrong, it will tell you if you do, and you won't mess anything up.
You should enter:
sfc /scannow /offwindir=D:\Windows /offbootdir=D:\

I got this response "There is a system repair pending which requires reboot to complete. Restart Windows and run sfc again" when I typed only "sfc/scannow" and pressed enter. So if I enter correct syntax, that may initiate test & repair thru install CD. What you think?

The error message is to be expected when you run "sfc /scannow" only from the install CD/DVD. I tried to explain this in a previous post:

When you run this command from your Windows install, you only need to use "sfc /scannow", but since you were getting error messages, we had to boot from the Windows install disc to run the command (this way your Windows install was not being used while it was being scanned, hopefully to get around the error message). The reason the command has to be entered differently in this case, is that when you boot from the Windows install disc, your 'working directory' is the X drive (created temporarily by the install disc). Because of this, it requires us to tell it the drive letter and location of the Windows install that we want to scan. This is likely why you weren't able to run "sfc /scannnow" without the extra file paths while you were working from the install CD.

Basically what I meant is, from the install CD/DVD you need to type the longer version, which tells sfc.exe where your Windows is installed. When you are booted into Windows 7 though, Windows already knows where it is installed, so that's why you can just use "sfc.exe /scannow" in that situation.

CBS report file in txt is 7.52MB, so I uploaded word doc file. But content of both is same. Please interpret it, but its vast technical going incomprehensible for me!!! Hope you decode it.

I will give it a look over, but 7.52MB is about 10 times the size of 880KB. Please make sure you have copied and pasted everything from the log file, save it to a new word document, and check the file size again.

I have a Netgear R6300 router that I got a couple months ago. It came with a desktop genie that is a crap program that was the root cause of hassles I was having with wireless dropping and popups of disabled/enabled internet connections.
I had to go into msconfig and also in services to disable it from starting up and running and don't use the desktop genie at all. I didn't uninstall it just incase but I access the router through http://192.168.1.1/start.htm without using the desktop genie.
I've had no problems since disabling that lousy desktop genie so I assume your Netgear DGN2200v3 router also came with the genie so take a shot in the dark, disable it and see if your problem goes away.
