Lenovo Ideapad s10 - 3c wireless problem

by desibeats / January 19, 2013 8:09 PM PST

I have got a really weird problem in my Lenovo Ideapad - S10-3c. Please can someone here help me out. Problem is my wireless connection goes on and off at random intervals. Initially it connects, and I can surf the internet. At any random time it goes off. (System gives a red cross with the message: Not Connected - Connections are available.) After sometime it becomes normal again and reconnects by itself. My friends use the same wireless network and they dont experience any such problems - so the router is working properly.

The interesting things are these, during down-time:

1. When I use the troubleshooter for internet connection, the report says:

A network cable is not properly plugged in or may be broken. ----- Detected (!)
Plug an Ethernet cable into this computer ----- Not run
Problem with wireless adapter or access point. ----- Fixed
Reset the wireless adapter ----- Completed
Investigate router or access point issues ----- Not run
Refer to Windows Help and Support for more information about wireless connectivity problems ----- Not run

I don't understand why something needs to be plugged in for a wireless connection? Is it a hardware issue?

2. When I go to Control Panel\Network and Internet\Network Connections:

It shows me two wireless connections,

Wireless Network Connection 1 - Not Connected - 802.11n Wireless Network Card
Wireless Network Connection 2 - Not connected - Microsoft Virtual Miniport Adapter

I tried disabling the second wireless connection but the problem persists.. please help me out!!

My friends use the same wireless network and they dont exper

"My friends use the same wireless network and they dont experience any such problems - so the router is working properly."

You may have talked yourself out of a bug I'm bumping into. That is, we see Netgear's latest firmware to do this but folk have the hardest time accepting it. The fix is known but I will not debate this at all. I feel folk have to get past this and when they do, then we can try things on the router.

If you know the fix, tell me about it - because that is why I came here for help in the first place.

Secondly, I used the statement,
"My friends use the same wireless network and they don't experience any such problems - so the router is working properly."
because it's logical.

My friends share the same router and wireless connection.

Also, we have changed 2 routers due to this issue, the latest one being iBall Baton. The problem still persists

If you can, help me out.

You lead with your statements.
by R. Proffitt Forum moderator / January 20, 2013 3:26 AM PST

The issue is pretty well known but usually it's the Ipad in the discussion. For the Netgear models we roll the firmware back a revision. The lack of detail hurts here as well as the statements about it works for others.

Try free wifi hot spots and if those work, it's the router.

Thanks Bob for your reply,

I tried using free wifi in a mall nearby my place - however the problem is still there. It goes on and off.

Another thing, we never used Netgear router models.

Can this be due to some hardware issue in my laptop? Or driver problem?

Waiting for your take on this.

Don't need more.
by R. Proffitt Forum moderator / January 20, 2013 11:35 PM PST

So the netbook has issues. At the shop we'll ask the owner to backup their stuff then restore it to the factory load. If that fails we replace the WiFi card unless they think that's too expensive which we'll offer the option of a WiFi USB stick.

It's a shame you didn't reveal country. For example a laptop set to NA region will drop/have issues in non-NA regions. That has to do with the WiFi channels. Easy to spot as you look at the router's WiFi channel setting and then see if your laptop can do that.

In reply to: Don't need more.

I have been searching threads for this problem. Same machine. Trying to figure out if this is a software problem ( new/updated driver) or if I have to replace some hardware.. (not fun)

Whats up? Is is a free fix? Inquiring minds want to know...

Not the same problem.
by R. Proffitt Forum moderator / August 21, 2013 1:06 AM PDT

But I am encountering folk that install an OS other than what the laptop came with. They would post a problem like yours. The solution is simple. Install the factory issued OS.

Answer
Wireless Channel Problem
by DavidChaze / September 3, 2013 12:18 AM PDT

In this case the problem can be because of WiFi congestion problem, so all you need to do is just open your router setup in the browser. Go to the wireless LAN setup and change your WiFi broadcasting channel from 1-11/13. Lets say if your channel is being set to highest or lowest one the make it in reverse order to select a middle channel. In this way your WiFi congestion issue will be resolved. Thanks
