Ask Slashdot: Updating a Difficult Campground Wi-Fi Design? 237
MahlonS writes "I am a retired network hack wintering in my RV in a campground in southern GA. 3 years ago I reconfigured the Wi-Fi system to a marginal working ability; It's now ready for a serious upgrade, prompted by a new cable net connection replacing a weak DSL. 5 dual-radio HP Curve access points connect to a 6th via single or double radio hops (effectively a Wireless Distribution System) in heavily wooded space. Unidirectional antennas at the APs (the APs are in water resistant enclosures) are placed on poles above the RVs, about 15 feet above ground. Primary hops are about 300 feet to 3 of the APs, secondary hops about the same. Signal measurements indicate that there is adequate RF between the access points. In 2008, average user count averaged about 30 users; newer devices (smart phones, etc) will likely increase that number (winter population total is about 80 RVs). While the old design worked OK when lightly loaded, I suspect that the single DSL line generated so many packet resends that the APs were flooded. This is a quasi-State Park, so money is always an issue, but there is enough squawk from the user community that a modest budget might be approved. The main AP connects to an old Cisco router. Burying wire is frowned upon, due to shallow utilities, and campfire rings that float around the campsites — sometimes melting TV cables. Since I'm not up on current Wi-Fi tech, are there solutions out there that would make this system work much better?"

Ah, getting back to nature and disconnecting.

Your opinion is valid. It's also subjective and irrelevant. And GP's post was rightly modded down for the same reason.

Putting wi-fi in a campground is contrary to its purpose. I don't care if the asker and the editors failed to notice this. I don't care if that rains on someone's little parade. It's a dumb idea. Whatever you're doing there, it isn't camping. It's using the Internet outside. That's my genuine opinion, and not only is it as valid as the asker's, it's more valid because it's more consistent with what a campground is for. Some ball-less soul-less sack of shit will mod me down anyway because he hasn't the guts to argue against me, but that's okay.
Except that a lot of people in RVs full time. That means their RV is their primary, and only, home. As such, they need access to their bank accounts, friends, relatives, news. For most people who full time, a campground with wifi is essential, at least once in a while.
My sister lives aboard a sailboat. Full time, all over the world. Wifi is huge for her. Without wifi, we do't know if she's alive or not. We have an RV; we don't fulltime but after 9 days it's nice to do laundry and catch up on world news.
We also backpack and spend a lot of time in the wilderness, so I'll stack my "camping creds" against yours any day. When was the last time you were in the wilderness, with a 2 day hike-out to the nearest trailhead? Are you spending your thanksgiving next to your computer, or in the high desert 20 miles from the nearest town?

Gives you something to do when it rains. Been there, done that. Not just directly, but indirectly, now a days you internet search for the closest stir fry place or whatever. Oh look we ran out of propane and the onsite general store sells one pound cans for $10 a piece and walmart 2 miles away sells them for $2 and we could pick up some more food at the community grocery store.. road trip!
Much as its nice to momentarily disconnect and go on a walk in a park, sometimes on vacation its nice to momentarily reconnect.
My parents mostly used it to upload pictures. "see, he caught a fish" that type of thing.

I don't think "communing with nature" is the point. I think cheap accommodation is. People like to be able to travel around the country in a moving "house." I once met, for instance, a guy who drove around the US for a year with his wife, with a camper hitched to the back of a small pickup, in order to see the country and, among other things, decide where they'd want eventually to settle down. I get the impression that many retirees, likewise, buy campers and go touring. It seems like a reasonable enough thing to do. I'd be curious to know what would be cheaper: that, or traveling in a fuel-efficient sedan and staying at Motel 8s.

It sounds like you don't exactly know where your problems are, so how can you solve them?
My advice would be to do some serious analysis of what's going on in your network. Hook up an ethernet sniffer to your internet connection and see what's going wrong. You suspect it's a lot of retransmissions do to the DSL, well find out if that's true. Consider buying a cheap spectrum analyzer (wi-spy can be had for under $100). Track when you get problems, and where. Throwing money and equipment at the problem is more likely to waste money and equipment than solve the problem. Since you're retired, it sounds like you're more short on money and equipment than you are on time to analyse and diagnose the problem.
Once you actually know what the problem is, then you can go out to the wireless community and ask for a solution. K You're seeing a lot of very, very different solutions here because people are guessing what the underlying problem is, largely based on what's worked for them. Obviously you can't follow all of them, but which one should you try? Knowledge is power, and ignorance is folly.

Stop being lazy and run freaking wire between the locations. you already have power there so you can run wire. you can use phone wire which is cheap and use ADSL modems for the links, again cheap.
Honestly there is no magical wireless setup that will handle the load, you have to run wire if you want to avoid performance issues.
