• The Device Manager windows will appear.
• Click on the sign next to Network Adapters and expand it.
• Right click on the Wireless Card and click on Properties from the drop down menu.
• Click the Power Management tab
• Uncheck Allow the computer to turn off this device to save power.

Also, change plan settings for the selected power profile. Here are the steps:

• Click Start > Settings > Control Panel.
• Double Click on Power Options.
• Click the Advanced settings.
• Set all option to maximum performance under Wireless Network adapter.

Observe the system performance and check if it makes any difference. Please reply with the information, I'll be happy to assist further.

I bought Dell vostro 3560 ~ 7 months back. It has a problem getting connected to internet ever since I had bought it. The problem is there while using both wifi and brodband. It keeps disconnecting every 30 sec. Whereas on other laptops the same connection works smoothly. 

Unfortunately, I bought Dell vostro as I have used Dell vostro 1400 for 5 years and the best part of that machine was that wifi used to work extremly well in that laptop. That was the only reason I selected  vostro laptop this time as well. Becasue of the internet problem I am not able to use my new laptop anymore.

• Type in 'devmgmt.msc' and click 'OK'.

Hi Saharsh,

I could not update the driver from the link that you have provided above. I have tried couple of times and here is the message that I kept getting everytime:

But I have done all other changes you that you have listed above. I  will let you know in case I see any improvement in the internet connection.

I am sorry I am ignorant about these things, but I also want you to know that I am having similar problem using LAN connection as well and I use a LAN cable/wire for it.  Will that also be solved by doing things related to wireless adapter only?

Hi Suruchi,

Please share the results of the system performance. Also, you browser to download and save the drivers instead of using Dell Download Manager. Here are the steps:

• Click on the link shared above.
• Click on Download File.
• The file will be download on the system
• Double click on it and follow the onscreen instructions to install the drivers.

Hope this helps. Please reply if you have any questions.

Hi Saharsh,

I am facing the same problem while downloading the updates as well. But I could download the drivers and re install it .  Also I realized after making  the changes suggested by you as above. My wifi stopped working at all. But than I figured the problem was with one particular change.

• Change Locally Administered MAC Address to 1234567890AB (This step is important)

At my work place we can access wifi after giving our MAC ID to the IT department. And I am assuming that doing this particular change changed MAC ID of the comp. So I did not do this change.

At least for last two days internet is relatively OK. I am not sure though what helped most.

Hi Suruchi,

Thank you for sharing the results. You may ignore changing the MAC address if it is a requirement for accessing the wireless connection in your company. The above shared changes and reinstallation of the updated drivers may have resulted in stable wireless connection. Also, please share which updates are not getting installed on the system and the exact error message that you get.

Please reply with the information, I'll be happy to assist.

Hi Saharsh,

I was able to install the updates as well. Presently the internet is working fine.

Thanks for the help.

Hi Suruchi,

Glad all is sorted for you. Feel free to reach out to us if you need any assistance in future.

We too have wireless issues with our Vostro 3560's. We have 10 of them running Windows 7 Pro SP1. They have the 1901 wireless + bt card in them with the latest software. They do not stay connected to the wireless access points, while our 12 Latitude 2120s. and the Ipads and Ipods do. Installing an external ASUS USB-N10 adapter fixes the problem. This is not the best solution as these laptops are used by middle school students. The access points are Ubiquiti Unifis and Cisco 4410s.

For me updating the device manager as suggested by Dell people helped.

But I still feel that the inbuilt WiFi adapater/card with this model is not great. I will buy ASUS USB-N10.

Thanks.

We've updated the network driver, the bios, and it still didn't help. The laptops will connect at first, but then not work on the network or internet.  The access points are using wpa psk for security. Right now I have them on the wired network. After we get past online testing in the schools I am going to contact Dell about this.
