My home wifi network is currently very unstable. I'm working to improve it and looking for a little advice. This is a little long but I'm trying to provide as much relevant info as possible. Thanks in advance to anyone who can comment. First, I have Comcast cable internet performance package (6mbps). My internet speeds vary from about 3-10mbps. I use the Comcast provided cable modem (rented). From the cable modem I run a cable directly into an Airport Express 802.11b/g to create my home wifi network. I have a usb printer attached to the Airport Express for network printing. I have a second Airport Express on the other side of the house used to expand the network and pump music into my home stereo via air tunes. I use my network for general internet surfing, airtunes streaming to my home stereo, and itunes and bittorrent downloading. No gaming or other speed intensive applications especially within the home network. I have two problems - the internet drops out and requires a reset very often - at least once a day and the airtunes is very unstable. For the internet problem, I thought it was the Comcast internet but I've checked the quality of the cable signal and removed all unnecessary splitters, etc and it still happens. I think the problem is my Airport express. For the Airtunes problem, this clearly seems to be an Airport express problem. I'm thinking of going to a Linksys WRT54GL 802.11b/g as my primary wireless router and purchasing a cable modem (to save money in the long run over renting.) Here are my questions: 1) Based on my usage and my current Comcast internet package, my understanding is that 802.11b/g is fine for me. Is this correct? I don't think I need or could benifit from the 300mbps speed of a N network. 2) Can I still use the airport express for airtunes and printing on the Linksys WRT54GL 802.11b/g network? 3) Regarding the cable modem, is there any advantage to getting a more expensive DOCSIS 3.0 modem such as Motorola SURFboard SB6120? I've read that some people see significant improvements in their speed even if they have a slower internet service. Hope all this is clear. Thanks to anyone who wades through it. Cheers.
