Okay, I am looking around to see if anybody knows of a way to tether a Droid. I already run PDANet and it works fine, but it doesn't allow you to visit any secured sites, so I can't check Gmail, or Yahoo mail, or a few other places I go regularly.
The paid version allows this, but costs $29. I don't mind paying it if I absolutely have to, but I was wondering if anybody knew any other program that might work, at a lower price.
I use EasyTether on my HTC Evo 4G. That's another Android phone and I don't think EasyTether was made for the Evo specifically, so you should give it a try. I can't say off the top of my head whether I've visited any secured sites but I'm pretty sure I've used Gmail while tethering. In any event, it's worked pretty flawlessly for me.
Also, if you're willing to root your phone, there are a ton of apps that will also let you do wifi/hotspot tethering. This also assumes you can stomach the risk of your phone company finding out (not likely, IMHO) and penalizing you in some way.
I will second Easy Tether also, just moved to a new apartment last week and have been using my EVO as my internet provider while I get Comcast or whatever is available in the complex. I'm able to do most of the usual internet surfing, even did a fantasy football draft while using skype call, it bounced out a couple of times but it worked! You can still receive text, mails through the phone but if a phone call comes in it will disconnect.
Essentially, you have three options: 1) As mentioned before, use the CAT5 Ethernet cable(s). This will give you the fastest (and most realiable) connection speed. Due to you using a desktop, the cable makes sense because you aren't moving anywhere.
