Hello, this is a copy paste from my other forum post through Lenovo (my laptop brand). 

 

I have received my Lenovo IdeaPad Y510P back from the repair center and I'm now experiencing issues with download & internet connection speeds.

 

I am getting approximately 2mbps download on Wi-Fi and over 120mbps when connected to ethernet wire. I have tried the following to get speeds up to what would be somewhat normal for the service we pay for through Comcast.

 

-Uninstall the Wireless NIC Drivers.

-Roll back the drivers.

-TCP/IP Stack Reset

-Edited Power Management Settings

-Edited some of the settings within the Network Card (Roadming Aggressiveness, etc)

-Releasing/Renewing the connection.

-Flushing the DNS.

-Run & Install all Windows updates.

-Tried all the Windows auto troubleshooting wizards (network adapters, internet, network, etc)

-Resetting the Modem

-Turning off all devices that could cause interference

-Purchased an external USB Wi-Fi card (Logitech), which this produces another issue. We have a 2.4Ghz and a 5Ghz connection. I supposedly have a dual band card (Intel N7260) and I can only connect to the 2.4Ghz network. The 5Ghz

network doesn't even show up. It showed up in Windows 8 but when I got the laptop back they had it updated to Windows 8.1.

 

Really at a loss here. I have internet but very minimal (can't download anything, slow loading web pages, only showing the 2.4Ghz network). This is also happening to my brothers laptop and brother in laws laptop on the same network. All of our cell phones are connected to the Wi-Fi and are working just fine. All of the desktops that are connected via ethernet work just fine.

 

We installed a home wireless security system. When we unplug them completely the speeds to get slightly better but I still can't connect to the 5ghz network nor see it on my computer at all. I would like to see if Lenovo installed a different card because everything I'm looking at points to the NIC being only open to 2.4Ghz networks. What baffles me however is when I plug in the external USB NIC card it doesn't show any faster networks. My father in law can plug the external USB NIC stick in his computer in our garage and pick up the 5Ghz network easily. 

 

Here is the results from doing an ipconfig /all command in CMD (Admin)

There are 3 versions of that card  acording to the Lenovo forums your model laptop does not support 802.11n 5ghz. Also your wireless speed will depend on the slowest device on your network. If you have an older device connecting at 802.11g/b the network will only run at that speed.

I sincerely appreciate your response. Before I sent it in for repair it had the card that could connect to a 5ghz WiFi network. I will be calling them about this issue.

Can you get the Hardware ID  number from the Device management page? This will identify which model card is installed in your laptop.

  1. Go into the start menu and type Device Manager.
  2. In device Manager right click on Intel® Wireless-N 7260 under network adapters
  3. In the next menu select properties
  4. Select the details tab
  5. Select Hardware Ids under the properties drop down box
  6. Right click the top entry, Copy and past the Hardware ID in your next post

It appears that model is 2.4 GHz only. You will have to check with lenovo with your serial number to find out what was shipped with it. According to the support forums it should only be 2.4ghz.

That's weird because up until it being repaired for other issues (which have been consistent video display errors with this laptop and the issues reoccurring with it even after it being repaired twice) it has always been able to connect to our 5ghz network. 

This laptop & Lenovo's support has been nothing but a year long of consistent problems & headaches. 


Also what I find weird is when I plug in the USB stick that I know can connect to 5ghz networks it doesn't pick it up. Any advice on that?

What make and model router do you have? What is the make and model of the USB adapter? Are your networks labeled different IE: homework and homewifi5g?
