Windows 7: Turn Windows 7 Laptop into Wireless Repeater with One Wireless Adapter

Actually, without wireless router, only a Windows 7 laptop can be turned into a WiFi hotpot or a wireless repeater. Many discussions can be found online regarding how to turn Windows 7 laptop into a WiFi AP or virtual WIFI hotpot, however, the internet surfing is based on a local area connection. If wanna extend a WIFI signal to an enhanced new wireless AP, generally two wireless adapters are considered.

Here, differently, with only one wireless adapter but without 3rd-party software, we can setup a wireless repeater in a Windows 7 Home Basic or Home Premium laptop with only one wireless adapter. This can boost the wireless signal to smartphones, tablet computers, or other wireless devices. Also, the mobility and flexibility allow extending the signal to a yard or a garage conveniently as you want.

It is known that a virtual wireless adapter can be created with a third party software or only Windows 7 built-in commands. But in Windows 7 Home Basic or Home Premium, usually the virtual wireless adapter cannot be created or a hosted network cannot be started. I found a specific approach to clear the issues.

We can follow the steps (successful setup in my two Windows 7 Home laptops),

1. Click Start, point to All Programs, click Accessories, right-click Command Prompt, and then click Run as administrator.

2. A virtual wireless adapter can be created by command of,

netsh wlan set hostednetwork mode=allow ssid=sameabcd key=12345678

where sameabcd is your new ssid of the virtual AP, key is the password for virtual AP.

If the virutal adapter named 'Microsoft virtual WiFi miniport adapter' cannot be created, we have a specific method here.
Delete all temporary point to point ssid at Manage wireless networks in Network and Sharing Center, and change all static IP to dynamic IP. Then bridge Local Area Connection to Wireless Network Connection (see Fig. 1), again run the command above, usually, the virtual wireless adapter can be created. If not, update the driver of the wireless adapter. If no again, it means the wireless adapter does not support hosted network. When the 'Microsoft virtual WiFi miniport adapter' is created, delete the bridge immediately.

3. Start hosted network by

netsh wlan start hostednetwork

If the hosted network cannot be started, similarly, we still have a specific approach here.
Delete all temporary point to point ssid at Manage wireless networks in Network and Sharing Center, and change all static IP to dynamic IP. Then bridge Wireless Network Connection to Wireless Network Connection 2 (as shown in Fig. 1), run the above command again, usually the hosted network can be started. Then delete the bridge immediately, and run the command again.

4. Go to Control Panel > Network and Sharing Center > Change adapter settings. Right click on Wireless Network Connection and select Properties. Go to the Sharing tab and check "Allow other network users to connect through this computer's Internet connection." Then at the "Select a private network connection" drop down menu, select Wireless Network Connection 2 and click the OK button.

5. Searching the new created wireless signal, you can now get your smartphone, tablet computer, or any wireless device connected to the new WiFi AP.

If do not need wireless repeater, just stop it by

netsh wlan stop hostednetwork

to stop the wireless hosted network.

This method is free and no any 3rd-party software is required.

After you set up the hosted network for the first time, you can just start or stop it by running following two batch files as administrator.


netsh wlan start hostednetwork


netsh wlan stop hostednetwork

Or only one batch file as attached. Attachment 233431

Hi I seam to be setting it up just fine with the netsh commands but I fear I might need to manually edit IP, Gatway on the 'Microsoft virtual WiFi miniport adapter' ? I dont know Im not sure could do with some help please.

Im running windows 7 Ultimate 32bit.

Im not connecting because any device to connect is trying to obtain IP address and gives up.

Internet works on the usb wireless network connection 3.

I found that I had to enable windows firewall before I could get sharing to work.

I run comodo firewall and tried to disable that and leave windows firewall running.

Some pics attached.

Where do I start to look for the issue?

Many thanks for looking.
