Home network security when using a cell phone

[Easto]

Am I compromising my home network security when I give a friend my wireless password so they can use my wifi while they are at my home? Can I setup 2 different accounts on my Dlink router so that one has full access and the other only internet access i.e. from a cell phone?

I have some free time today and I'm thinking of resetting/tweaking my wireless router settings, so if I'm going to be in there I might as well setup an additional "cell phone" account. I have the link to the Dlink site that explains a lot about setting up the router, I was just wondering what setting I may have to look for etc.

I haven't seen issues by letting cell phones on the network. I suppose someone could have tools on a smart phone that would allow them to dig around your network intentionally looking to damage or mess with things. But as far as letting malware into your network, I'd not worry about it. If your router supports "Wireless Client Isolation"...enable that feature, it vlans each wireless client so they cannot see anything else on the network.
