Wired and Wireless networked together

Hello,

I think that you should check first that your computers have shared drives and the printer (supposedly on your sister's computer) is shared too.
The second problem could also come from a firewall.
If you have one installed you should allow the computers' IP addresses to be accessed.
Mixing wired and wireless computers in a router (that is equipped with both) is no problem.
Good luck.

Your problem is most likely in the way that you have setup the Wireless Router since you can see her machine but not access it the most likely thing is that the router is blocking the connection.

I'm taking it for granted that you have shared something on each computer as well because if you haven't you should be able to see both computers in Network Neighborhood but no shared components so you can not access the files or printer if that is what you are trying to do.

Because you are using a wireless connection you'll need to pay particular attention to [b]Security[/b] as well because once you have this up and running you don't want anyone to browse the contents of the HDD's involved or worse still use a unsecured Wireless connection to access your ISP and download restricted data which the account holder will be responsible for. It doesn't matter if there is any copy of the data on any of the networked machines the fact that it's been downloaded through that connection will make the account holder guilty of an offense.

Best case scenario is that someone will run up your ISP bill and you'll be hit with excess charges and it gets worse from there with the possibility of jail time involved and the account holder being placed on [b]The Sexual Offenders Register[/b] or worse depending on what has been downloaded through the wireless connection. Remember that this has a range of 500 meters so someone doesn't even need to be overly close to gain a connection to your wireless network and Internet through the wireless connection.

Once you have the router working so you can share data between computers engage the WEP security that is built into the router and restrict the number of computers that it will allow to connect. While this is not positively safe it at the very least will keep out all but the professional hacker.

The most likely reason for this is that you have different workgroups or the router isn't set to allow transmission from the Wired to Wireless side of things.

Routers can be painful to setup sometimes particularly when you combine several different technologies in them like the DSL Modem/Router/Wireless Hub.

If you have access from your sisters computer and not yours and everything was set exactly the same way in the Network Setup Wizard that only leaves the router preventing the wired side of things from seeing the wireless side of things. As your sister can access files and see your computer.

Can she transfer files to her computer? If she can see them but not transfer them over the network that would point to a problem in the router setup that needs to be addressed as well.

The MS networking won't broadcast over the WiFi, just like it won't broadcast over a WAN connection.

You will need to set this up by the static IP address of the system you want to share out.

As you have chosen to put the printer on the laptop, this will make a few obvious problems.

First, if she takes her laptop anywhere, you can't print.

Second, most wifi is set by default to DHCP as it makes it easier to come and go between networks.

Move the printer to the desktop that will always be in the same spot and give the PC a static IP address. Then on the laptop when you go to setup the network printer you can put in \\192.168.1.100\hpprinter Or whatever you share it out as. I STRONGLY recommend NOT putting any spaces in the name under the "share this as".

I do this regularly and it works like a charm.

Another option is to get a wireless printserver so it will become a networked printer, not dependant on either system. Linksys has several affordable options.

Good luck!

These two sites helped me when I was setting up mine at home:
Comcast.net and networkmagic.com
Best of luck
