Wireless Routers for Congested Areas?
An anonymous reader asks: "I have been living close to campus at UW Madison for the past six months or so and have come across a problem. We, along with everyone else in the area, have a wireless router, both a Belkin 54g and a Linksys WRT54G. We have Charter 3 Mbit down/.25 Mbit up cable and 6 guys in our apartment. Just on our block about 15-20 people have routers. We are constantly plagued with problems connecting to the wireless, staying connected, getting connected after rebooting, hibernating, and so forth. We have to reset the cable modem and the router many times a day to get everything rolling again. I am thinking that the router is the problem, because my dad always told me that's why they have twenty dollar routers up to thirty thousand dollar routers. What router can I purchase that will help my situation and will work well in a congested college area?"
No, it' sonly illegal to go over the maximum power output regulations. As long as you do not combine and modify equipment to operate above regulation, it's legal. That's why you can buy higher dBm antennas in Walmart, they're designed to stay within spec. It's not illegal to boost power at all, it's only boosting power over regulation that's illegal. Here's a link to a Cisco support page listing some specs.

Your experience is par for the course. Get some CAT5 and your troubles will vanish.
Sort of like saying "SUVs are safer in a collision." Well, yes, if you hit someone smaller, but if everyone owned SUVs their advantage would disappear and we'd just be using more fossil fuels.
I regularly plug in my laptop when I have a lot of stuff to transfer, such as a full backup. Gigabit Ethernet still beats any form of 802.11.
It may seem counterintuitive, but one good way to reduce your interference to your neighbors' WiFi networks is to put more access points in your own house. This is especially true if you can't cover your whole house with a single access point. Above all, resist the antisocial temptation to get a power amplifier. Use the cellular approach instead.
Get more access points, spread them across channels 1, 6 and 11 and sprinkle them around your house. Set them all to the same ESSID and plug them into an Ethernet switch (if the access points have built-in routers, use no more than one so all the access points will be on the same logical Ethernet segment.) Your laptop will automatically hand off to the nearest access point when you move, just like a cell phone.
Even if you can cover your whole house with a single access point, having several reduces your average radio link distance and lets the links operate at a higher average speed. (802.11g runs from 1 megabit/sec up to 54 megabits/sec, depending on signal-to-noise ratio). Most WiFi transmitters run at constant power, so increasing your average data rate reduces your transmission time and the interfering energy you dump onto your neighbors for each megabyte of data you transfer.
Well, I wouldn't go this route, but you could easily go with A instead of G, then you won't have the cordless phones, microwave, people down the street, etc using the same frequencies. It may not be the cheapest solution, but is probably the best legal solution if you have to stick with wireless. If you want to stick with your wireless G equipment, I would go with directional antennas as they can be bought or made pretty cheap. Also, if you can stick your router in the basement and point the antenna upwards, then it will only receive strong signals from within your building. That should eliminate most of your interference. The best solution in my opinion would be to go with wired, esp when you are sharing all of your 'study materials' you will be able to transfer all of those educational videos a whole lot faster without worries about interference.
It's behavior like this that hurts open source software and hacker friendly hardware. Just because you can, doesn't mean that you should. Besides being a violation of federal law, it encourages the FCC to require tamper-resistance as a condition of type acceptance for more kinds of systems.
