Solved Why is my laptop not on the home network?

August 7, 2014 at 14:44:32
Specs: Windows 7
Until one week ago I could print from my laptop to my wireless printer. Now I can no longer do this, although two other laptops on the home network are successfully communicating with the printer.
I have gone to the device manager and found that the network adapter to be turned on and updates are ok.
The error message is that the laptop is no longer on the home network. How? Why? How do I get it on the home network. The troubleshooter does not explain this.

It may be simply that you need to uninstall and then re-install the printer to "your" laptop. I have had that situation happen on the odd occasion.

Is your printer wifi only (no ethernet/cat-5 option)? Or does you printer provide for a cat-5/ethernet connection too?

Your other laptops can communicate with the printer (via wifi...). Can they also communicate with each other; and also with you? If not - did they ever?

However you say that "you" appear not to be on the home network (lan); which"may" actually be the reason why you can't print either..?

Can you actually see the home wifi lan - its SSID - in the list of wifi access points available? If not... and the other laptops can...

Have you considered uninstalling and then re-installing the drivers for your network card(s)?

Is your home lan "all wifi"; as in do you normally connect to your router (and thus home lan) by wifi only; or do you connect to it via ethernet/cat-5 too?

No bearing here on your "not on home lan" aspect - but useful to know any way... How is your printer included in the home lan; is it via cat-5/ethernet cable into the router - or is the printer only wifi in itself (and no cat-5 option)?

Does your router use any form of access control - besides the usual password/access key to allow you to connect to it via wifi? Access control is a specific area within the wifi management/setup of the router. Typically it has these options.

No security at all - no password required to connect (which means "anyone can connect..."); not at all wise.

Security password required to connect.

The SSID is either hidden or (not); or can be changed and then broadcast...; and in either situation the password/key is again an option (or not).

There is a section call MAC - Media Access Control. This is where you have three options: no MAC invoked/used; allow only those devices (computers etc.) who are listed to access and use the wifi; bar/block those listed etc. from using the wifi.

The computers/devices listed are identified by their network card i/d (also conveniently called its MAC); and each is unique/fixed (for the most part...).

What make/model printer; and while you're at it the router too?Also make/model of your laptop; and confirm the OS. Did you download any updates recently after-which the two problem(s) appeared as you describe?

✔ Best Answer
Try this.

1: Go to Network and Sharing Center in Control Panel.
2: Click change adaptor settings on the left hand side.
3: Right click the network adaptor (if you have more than one you may need to do this on all of them).
4: Select "Properties" from the list.
5: In the "This connection uses the following items:" select "File and Printer Sharing for Microsoft Networks".
6: Click the "Uninstall" button.
7: Click "Yes" when the confirmation box appears and wait for it to uninstall ("File and Printer Sharing for Microsoft Networks" will disappear from the "This connection uses the following items:" box once uninstalled).
8: Click the "Install" button.
9: Select "Service" from the "Click the type of network feature you want to install:" box.
10: Select "File and Printer Sharing for Microsoft Networks" from the "Network Service" box.
11: Click "OK" and it should install in less than a few seconds ("File and Printer Sharing for Microsoft Networks" will reappear in the "This connection uses the following items:" box once installed).
12: Restart the computer.
