Is there A New Thing That can Interfere With My WIFI ?

OK, this has happened to three of these laptops so I will temporsrily rule out a hardware failure

It says "Windows cannot find any networks". The problem is intermittent and can happen again in five minutes or five days.

As this is happening I am remembering something from the past. We bought a cordless camera and set it up and the cordless phones in the house would no longer work, unless you were within inches of the base. This leads me to believe it is some sort of interference. We are taliking three laptops here, and the problem is getting worse. And thsat is cannot find ANY networks means the wifi in the house is probably not going bad, or it would have found the other ones in the neighborhood.

I do not have a spectrum analyzer, but I do have an old YV woith a UHf band if that would help.

See now I am in a state where I don't want to call the ISP because if they semnd me a new MODEM they might say I have to but a new PC because mine is not compatible. I swear the next person who says such shit to me is getting a bullet in the brain. I will hunt them down even if they are in fucking Pakistan.

Last time I went into that it was about a router that I paid good money for and tech support said they no longer supported 98SE so they could not even give me3 a walk through on the phone on how to manually set up my internet access. I said "Hey MF, did my fucking money expire ?". What's more this was AOL on DSL and was $55 a month. But it wasn't their problem. the highest priced end user service in the world and they got nothing to say ? Hello ATT and goodbye AOL.

But anyway if nothing else I will just go buy a CAT5 cable, in fact two and get me old basement box back on the network. But it wouild ne nice to have wifi in the garage.

There is a way to get a quick and dirty SA for less than $ 20. You buy
one of the usb tv tuners off ebay and download a free program like SD
Sharp.

http://www.ebay.com/itm/Digital-USB-TV-Stick-FM-DAB-DVB-T-RTL2832U-
R820T-Support-SDR-Tuner-Receiver-HH-/111777588698?
hash=item1a0676a5da:g:xkYAAOSwVL1V~7Ma

That tuner is for the European type TV signals and not for the ones in
the US. It will turn any computer into a receiver from about 50 MHz to
2 GHz.

See if you can find a WiFi scanning-and-analysis application which
works with your variety of Windows and your particular WiFi card.
They're sometimes called "site analysis" programs.

Depending on the WiFi adapter, it may be able to read out the noise
level on each of the (overlapping) WiFi channels, as well as any
actual signals it finds.

Microwave ovens emit RF in the same ISM band that WiFi B/G use (2.4
GHz). So do many other devices, including many cordless phones.

Doesn't work with Wi-Fi. I've tried it. Two problems:

1. The tuna doesn't tune the required frequency range:
RTL2832U / E4000 64 to 1700MHz with a gap 1100 to 1250MHz
RTL2832U / R820T 24 to optimistically 1850MHz
There are other chip combinations, but I don't think any of them will
tune up to 2500MHz.

2. The maxiumum RX bandwidth is 3.5Mhz. The typical wi-fi signal is
25MHz wide with an option to go to 40MHz. You can try to
asynchronously sweep the larger frequency range, but the display will
be slow and ugly.

There are 2.4GHz RTL-SDR spectrum analyzers that do cover the range
using a modified DirecTV upconverter:

No experience with this, but it looks promising.

You can do better with a converted wireless mouse dongle:

I have the original Wi-Spy dongle. Works ok, but is not terribly

Before I spend any money, I'd go to the playstore and put wifi analyzer

Hardly. The three laptops have one thing in common. They're all

Ok, it might some kind of interference, probably being picked up by
your wireless router. Move it away from the window and put it behind
a wall that keeps your neighbors RF junk from trashing your wi-fi. So
far, the most common and obnoxious sources of interference have been
wireless video security cameras and wireless streaming media players.
You'll see the media player on a wi-fi sniffer, but the video cameras
require a spectrum analyzer. The most common "disconnect" or "can't
connect" problem is out of date firmware on the router.

As "Mike" suggested, sniff around with an Android phone or tablet
running "Wi-Fi Analyzer":
<https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en>

Here's a list of possible interference sources which I helped scribble
many years ago:
<http://wireless.navas.us/index.php?title=Wi-Fi#Interference>
The list is old so none of the modern abominations are listed (media
players, wireless TV cameras, portable hot-spots).

>But anyway if nothing else I will just go buy a CAT5 cable...

CAT5e is usually faster and certainly more reliable than wireless.

''well then that running out is even more temporary. The old router had a good wireless signal, and I had a problem with he interior net, but it would lose the DSL and thus the internet. Howeveer I went hunting around what these Women hooked up and it was quite possible there was a DSL filter in line with the MODEM. This would of course result in a low signal. But not RF. This is RF, I lose the whole network.

I might just pick me up some CAT5 cables and be done with it.
Nobody but me is using the RF, so maybe just shut the shit off.

Cheapest I found CAT 5s was online for like five bucks. At this point I need two of them. They are probably three times that much locally. Maybe I got some of that Yid blood because I really do not want to pay $30 for what I can get for $10.

Not to forget I need like about 75 foot of it.

This is not that much fun. The house has hardwood floors so any drilling is at the corners. I wish I was at MY house where I could just drop a drill wherever I damnwell please. Someone kill me.

Maybe I just go back to wire.

See if you can set up your access point and devices to use an 802.11
standard that operates on 5 GHz instead of 2.4; I don't know how it is
at your Old Kentucky Home, but in urban/suburban areas around here the
2.4 GHz band is crowded with trash.

There's a program/app available somewhere that lets you input your
home's floor plan and location/parameters of your WiFi router
and it will solve the Helmholtz equation in real time to give you an
idea of where in the home the signal will be strongest

Microwave ovens knock my connection *clean* out, even if the oven is 3
times further away than the 'puter from the wireless router. The
screening they use in modern ovens is obviously not very effective.
Perhaps the OP has a new neighbour moved in with a uWave?

Always amazes me how they put xGhz through CAT5 over *long* runs with
negligible loss. But TX line theory was never my strong point and I
really should brush-up on it.

 

[pfjw@aol.com]

Our neighbors just installed one of the wire-free security systems in their house, after which WiFi on that end of the house ceased to work, full stop.. For $22 from Amazon, we purchased a 'signal booster' that solved the problem quickly and easily. Our neighbors offered to pay for it, but we declined. They are very good neighbors, and we needed to do something anyway as the distance from one end of the house to the other is just under 60 feet. Add 11 feet floor-to-floor, and it adds up. Put another way, the west side of our house is closer to our neighbor than to our WiFi device.

But, it could be something as simple as that - a system nearby that is stepping on your network. And, that can be anything from a Roomba to a Nest thermostat - or one of the new wireless security systems.

Our very-vintage desktop is hard-wired and has no issues at all. The rest of the devices (cell phones, laptop and tablets) are WiFi, and fine, now, with the booster.

Cat5 doesn't work that well with 1000Base-T
Minimum requirement is Cat5e or better.
<http://www.cablek.com/technical-reference/cat-5---5e--6--6a---7--standards>

The "big thing" with the faster cables is the specified slightly
different "twists per inch" of the pairs to cut down on the amount
of cross talk between pairs.

Mpffff... we just got back from a tour of Cuba (mostly Havana), and after experiencing "High Tech" there, such complaints as I see here are laughable. We got 'internet' in the morning from about 7:00 am to about 9:00 am, when the bandwidth was sucked up by 'official' uses such as government and schools. Downloading a single page took perhaps an hour, and uploading - well, forget it. Cell coverage (ATT/Verizon/T-Mobile) was excellent, however. But at $3 per minute for phone, and $0.50 per outgoing or incoming text. But, one could purchase a SIM Card for about $10 CUC to solve that. We left our devices on Airplane Mode and enjoyed the quiet.

Yes, we did ride in several 1950s Taxis. One, a Buick with a Mercedes drive-train, the other a Ford with a Mitsubishi drive-train (both diesel). And, the rum, of course.

Are you allergic to supplying equipment makers names and model
numbers? It's really difficult to visualize your problem without that
information. Also, some routers have a reputationg for flaky
connections, such most everything Comcast calls a "gateway".

The DSL filter has nothing to do with the wi-fi connection.

Whatever works for you.

that much locally. Maybe I got some of that Yid blood because
I really do not want to pay $30 for what I can get for $10.

You don't know the first thing about being a Jewish negotiator. Around
here CAT5e can be found by the roll at the recyclers. The building
installers dump their surplus stock after each job. Typical is about
$0.05 to $0.10 per foot. However, I have to be careful so that I
don't end up with plenum cable, waterproof cable filled with sticky
goo, or shielded which never seems to fit the connectors. Caveat
Emptor.

>Not to forget I need like about 75 foot of it.

Buy 100ft. Having extra cable is always better than too short.
Measure twice, cut once. In your case, maybe measure 5 times.

This is not that much fun. The house has hardwood floors so any
drilling is at the corners. I wish I was at MY house where I
could just drop a drill wherever I damnwell please. Someone kill me.

Temporarily remove the baseboard trim near where you want the cable to
go through the floor. Drill as close to the wall as possible. Use a
drill that is much longer than you probably own so that you can go
through a floor joist if necessary. Notch the back of the baseboard
trim and run the cable up to a "muffin" jack (box with RJ45
receptacle). Replace baseboard trim.

>Maybe I just go back to wire.

There are also HomePlug adapters. Figure on about $80/pair.
<https://www.netgear.com/home/products/networking/powerline/>
I use these when I'm either desperate or lazy. They work but are a
problem if the wall jacks are on two different phases.

Nope. The "filter" puts the line pair straight through to the router.
What it is filtering is the voice frequencies for the phone.

Do it. It'll fix your problem for sure.

fuck's sake. Buy a 305ft reel, run the cable and terminate it yourself.
it isn't hard.
