Lead-Lined House causing connection problems

Hello

I have a job lined up for Tuesday; a woman has been complaining of dropped connections, poor wifi signal, and the like. My first thought that it was no big deal, and that I could just extend coverage by adding another access point on the ground floor of her two story home so that the signal would reach all of the house. Her house is right on the border between Iowa and Illinois in a fairly rural area.

However, she also added that often times cell phones won't work in her home, and that all of the computers in the house will sometimes stop working if there's a sudden drop in temperature, a sudden change in barometric pressure (such as a storm rolling in), and so on. This had me puzzled, and then she mentioned that significant portions of the house (either in the walls or the frame itself) are lined with lead; her house is about 150 years old.

I thought of two routes to take, concerning the networking side of it:

1. Run a line from the router (in the basement) to her bedroom (ground floor) to connect her laptop directly to the router.

2. Set up another access point and just hope that it can reach everywhere.

Her main priority is reliability. She doesn't need a fast connection or anything, just something that works the first time, every time. Any help in accomplishing that would be greatly appreciated.
 
Is it really lead lined walls, or just a really serious amount of lead paint?

I'm not sure, but would it really matter? I don't think they'd be willing to repaint. They're an older couple living in a rural area, they don't like change very much.
 
No, it doesn't matter, I was just curious.

I'd go with trying a second AP personally.
 
Well i'd normally have said burn the house down and build another but I wouldn't want that lead in the air.

If it's at all possible I'd run hard-lines. If superman can't see through it. 802.11 isn't going to either.

just be careful of lead exposure.
 
Set up a multiple AP run with hard ethernet runs to the AP's to the main router. Make sure to do an analysis of the 2.4GHz and 5GHz, it doesn't need to be anything fancy, just use some analysis software and your built in wireless in your laptop(though if you have access to proper hardware and sniffer/anaysis set up, go for it), and find out what type of interferance, if any, from neighboring networks and other sources.

Reason I say to sniff both 2.4 and 5GHz is that 2.4 often has better penetration, if you can get a clear/noise free channel range. Other than that, make sure that when you do all this, that all her devices are at lleast 802.11G, or just go ahead and upgrade them all to 802.11n.

How much are they looking to spend anyways on the ultimate solution/system plus your time and labor anyways?
 
Is she really using wireless as in roaming around with a laptop? Or are there PCs around the house that are desktops/towers...so that you could go with a much more reliable setup like bridges such as MOCA or Ethernet over Powerline adapters.
 
What's the square footage of the house? Lead can and will mess up RF pretty badly depending on how much is actually there.

It's the other way around. 5ghz has better penetration (that's what she said :p) and 2.4ghz has longer range.

You won't be able to look at 5ghz traffic unless you have a card with 5ghz radios. If the house isn't huge, a single AP with 5ghz radios can solve your issue. Although nobody here can tell you exactly what to do. That's up to you and what the surveys and test results show.

She doesn't roam with the laptop, it just sits on one desk in her bedroom. She said her husband just surprised her with it one year for christmas, and she said if anything she wished he would have got her a desktop. I was thinking if the laptop isn't actually repairable, I'd just offer to build her a cheap i3 setup for reliable use.

I take it this would work just fine? http://www.metageek.net/products/inssider And I don't think they're too concerned about the cost. So long as whatever I do works, they're willing to pay.

I'm leaning towards this, to be honest. It's a bit cheaper and I know it will work.

I had another question though: for running ethernet cabling through their walls, does it need to be specially shielded in any way to keep the signal from messing up due to the lead in the walls? Also, is it very important to avoid running the cable itself near any other lines, like electrical or plumbing?

I appreciate all the help.

I'm not positive, but average square footage for a two story house out here is about 1800sq ft, not including the basement (if any).

FYI, no one actually lines their house with lead (unless this was a strange cold-war-era nut job owner). its probably aluminum siding that kills the signal, my friends house is the same way.

ethernet cable will not be effected by any lead in the walls (if there were any). you will not be effected by any lead in the walls (if there were any), unless you were to chew on it or inhale particles from sawing thru it or something.

Also, is it very important to avoid running the cable itself near any other lines, like electrical or plumbing?
its good practice to keep ethernet wires away from other high voltage or high frequency wires when possible, though dont go too far out of your way. you wont notice any performance hit on a regular ethernet connection on consumer grade network equipment.

So since she doesn't move around with it...she just uses it on her desk, I'd say screw wireless, make it easy on yourself, make it reliable for her, all while keeping the costs down..go ethernet over powerline or MOCA (if she has coax in the bedroom) to bring internet to the bedroom. Could even give some wireless roaming in the bedroom and sling an access point in there.

Quick 'n easy 'n reliable and you're done.

Would doing this be any easier than just running an ethernet cable from the router on another level of the house, through the walls and up into her bedroom?

My concern with using ethernet over powerline is that I'm pretty sure the house gets fairly dirty power, which is why all the machines stop working when storms roll in.

Well..takes a couple of minutes to plug in ethernet over powerline adapters.
As for how easy running ethernet is this ladies home will be...I can't answer that...I haven't walked into the house and looking from point A to point B and determined what my approach would be, construction, distance, options, etc etc etc.

Last home I lived in during my transition from prior town I was selling my home in, to current town where I just purchased.....in the meantime I rented an old 3 story farm house...very VERY old, horrible quality electrical..typical old (rental). Powerline worked fine.
 
If you're worried about powerline failing because of dirty power, wouldn't the routers, etc blink as well then, even if they are wireless?
