But what is your question?... Why TeamViewer does not connect or why the wireless adapter does not connect?

teamviewer doesn't connect as wireless doesn't connect

Assuming your wireless is not connecting and/or dropping, try 4 things:

1. Make sure in Power Management that the wireless card is set to Maximum Performance AC and Battery. In Device Manager, properties for the wireless card, uncheck the setting to Turn this card off to save power.

2. Try deleting and then re-making the wireless profile for connection. It could be damaged.

3. Try upgrading the driver for the wireless card.

4. Try upgrading the firmware in the site router.

hello thinkpad _ user

 done

 it is a PC connects to enterprise wireless , but this PC wants to access remotely through team viewer . when wireless becomes "fair" signal it doesnt connect and it stays without connecting

JohnBusiness Consultant (Owner)Commented:
So if I understand this correctly, without Team Viewer, this PC connects with "good" or "excellent" signal and stays connected.

Then with new wireless driver, new wireless profile and enterprise firmware, the signal stays "good" or "excellent" without Team Viewer.

Now we run Team Viewer and the wireless signal drops to "fair".

I have to say I have not seen a regular application kill wireless in about a decade of wireless use. Strange.

Have you checked for viruses?  Viruses are exceedingly common and account for a large number of "strange behaviour" symptoms.

Have you tried uninstalling Team Viewer?  Then restart and install it fresh.

Sounds like the laptop(is it a laptop) is far away from the router - how far is the laptop from the router exactly?

How often does the signal show 'excellent' and how often does it drop to 'fair'?

What is 'fair'? 3 out of 5 bars?

@techp - Your most recent post says wireless signal strength has nothing to do with Team Viewer. That was certainly unclear before.

So concentrating solely on wireless and you did everything I asked of you (4 points), then there must be 1 of the following:

1. A range issue - too far away.
2. Incompatibility between router and wireless card (e.g. old router, new card).
3. A weak wireless card.
4. A weak router.

all above are invalid.....another computer is connecting automatically

A range issue - too far away.......it is questionable matter...as sometimes it connects proper.....sometimes no

Is this a laptop? If so you may have a lose wifi cable in the laptop - there are 2 cables that connect the card to the aerials in laptops - black and white

I've opened laptops before and seen issues where one of the cables aren't connected...that could explain it

That another computer works properly does not invalidate my suggestions. I have seen it happen.

You need to get a better understanding of wireless cards.  The wireless card could be defective  (weak) in the problem computer. That does not extend to another computer.

Yes, if another computer works, the router is probably not weak.

But if the router is G and the problem computer is N, it is easy for there to be an incompatibility.

Wireless is as much an art as a science.

changed wireless usb adpater

changed wireless usb adapter

That was a very helpful test. You know the other computers are fine also.

So at this point, there may be something wrong with the operating system on the problem computer.

1. Scan for viruses and malware including Malwarebytes.

2. Consider trying a Repair Install. The method for Repair Install is related to the operating system. What operating system is it?

3. If you are so inclined and wish to save time, you can consider backing up the computer and reinstalling Windows.

Ok, can you give us this info...

1) When its working - have you 5 bars on the signal strength?
2) When its dropping - how many bars are showing for signal strength?
3) Are there any microwave ovens in between or close to this area? Cause they cause interference
4) Wireless phones - any in this area? They also cause interference...

If you've 5 bars and its dropping to 2-3 bars I'd guess interference from another source...

Is this a single router providing the wifi? No other access points in the network anywhere?

good questions


Ok, can you give us this info...

1) When its working - have you 5 bars on the signal strength?  when signal is excellent . disconnecting when it is fair
2) When its dropping - how many bars are showing for signal strength? may be 2 or 3
3) Are there any microwave ovens in between or close to this area? Cause they cause interference ....no microwave
4) Wireless phones - any in this area? They also cause interference... ofcourse...people have smartphones....they may connect also

If you've 5 bars and its dropping to 2-3 bars I'd guess interference from another source...

access point signal strength is excellent sometimes

smckeown777Commented:
'access point signal strength is excellent sometimes' - this doesn't answer my question

Do you have 1 router providing wifi?
Do you have other access points in location providing wifi? If so how many?

Could it be that you are between 2 wifi points? Need more info on your setup if you don't mind...

Also by wireless phones i meant the wireless handsets you see in houses - not smartphones...wireless handsets will cause wifi interference

Ok so that itself is an issue...because its possibly you are jumping from one AP to the other...

Same SSID on both? So they can roam between?

Ok so that might explain it...

Ways to verify/test

I assume you can access the web interface on the router - when the client is connected and excellent signal login to the router to see if they are indeed connected to it - there's usually a DHCP client section or a 'Connected client' section to review all active connections to the router(what model do you have?)

If you see that they are infact connected to it then that's a starting point
Once they lose connection do the same - login to the router and check the connected clients list - I'd guess you'll notice they AREN'T connected to it...in which case they are therefore connected to the Access point...

Again this is the best way to determine where the issue lies...if you see they aren't connected then at least you then know its connected to the weaker AP...

What's the fix? Move the client either closer to the main router or to the AP...or move the AP further away

That's how I'd troubleshoot it anyways...sure let us know
