Wifi anazlyzer help.

[emil77]

So not to piggy back on the thread below, I downloaded the wifi analyzer app from the google play store. I'm also having a problem with WiFi connection. My fiance's IPAD barely has a connection in the house using wifi.

The wifi router is in our office with the living room being about 50 feet away. The wifi device is a Netgear N 300.I am looking at the analyzer and wifi channels the graph goes from 1-3. The signal strength keeps on jumping up and down. It ill go from -90 to -40 then back down. Does that give a clue as to what's going on?

Not really. It means the signal strength is fluctuating and inconsistent, which is why it's not working very well.

Nothing to tell you what's causing the interference. Likely it's just too far from the router.

The thing is I was sitting right in front of the router while running the analyzer.

50 feet is not that long. Netgear N 300 supports according to the spec 802.11b/g/n with indoor range of 115/125/230ft accordingly. It may be interference from wiring inside walls (just a guess). I have a small network at home and my kid's laptop on the next floor right above the WiFi router was loosing connection all the time. I resolved it by adding a repeater in another room. You may try to add another Netgear router as a repeater set to "n" for better bandwidth with your main router.

In simple terms how does a repeater work? I found this one on Amazon: http://www.amazon.com/Uspeed-Repeate...less+repeaters
I don't get the idea though, do I just plug the repeater in? Does it need wires ran to it? Can I buy a repeater, put it in my living room area and just plug it in to an electrical outlet and it's good to go?

Go check this out...

Once you set it up you can disconnect the Ethernet cable... Looks pretty cool to me...

There are a few possible issues there. What would be good to know is what kind of noise and physical errors the device is subject too. Are there other APs out there near the same frequency? db moving jumping from -90 to -40 is something that needs a little more looking into. Also is it an issue in a specific location(s) or everywhere? If you are in the same room as the router, what is it doing? The same?

It is just re-transmits the signal from your router making the signal stronger for remotely located devices. The repeater can use 801.11g or n with the router and 801.11 a or b with the endpoint device if the device does not support g/n. The easy way is to call the vendor's customer support for instructions. Does your iPad work reliably somewhere else (any other network like other office, Starbucks, etc.)? Sometime it can be a case of a malfunctioning device. These days mass production boards are typically not tested since it is cheaper to replace them then to test.

If your right in front of it and you see the signal level fluctuating that much it might be the antenna on the wifi router. If it has an external antenna make sure it's screwed down/plugged all the way on. You might try wiggling it around a bit.

Also, if you can swap the power pack for the wifi router it might be a problem with the DC voltage. If the power pack voltage is low (or to high) it will cause poor operation.

Turn off your router & walk around with the analyzer running. From your info I suspect co-channel interference (Too many radios on the sane channel) is the problem.

802.11 in the 2.4Ghz needs adequate frequency separation. In real world terms that means only channels 1, 6 & 11 are usable in most cases. Checking with your router turned off should provide a decent view into what may be affecting things.

Best bet, if your devices are capable, is to go to a dual-band (2.4 & 5 Ghz) radio. The 5ghz band uses narrower bands & is less susceptible to co-channel interference. Make sure your radio (access point or router) has a dual band radio (run both 2.4 & 5 at the same time) so all your devices will work.

There are some good tips about 11 minutes into this video. Little things link making sure the router isn't sitting on a steel cabinet, that there isn't metal between the iPad and the router, and that the router is facing the right way. BTW the aluminum foil trick works.

Change your channel on your wifi router/ap.

THAT might clear your problem up.

Long story short, I installed a CISCO RVS-4000 and a 4410N access point for wifi and connection was ****TY on two channels, but as soon as I moved to channel 7, BAM! Everything was up and no more inconsistent connections and slow performance and all that. All has been running nice and smooth for a while now.

Change your channel on your wifi router/ap.

This, and try to move other current away from the router: power cables, fans, bluetooth dongles, monitor, PS3 remotes, etc.

Thanks guys! I think that was it. I changed the channel to 11 and so far the IPAD works great! Hopefully this solves my issues.
