Add settings options to display/hide graph legend per graph type
Channel graph legend - default display false
Time graph legend - default display on the left

Hi guys.

Thanks for this great open-source tool. :-)

I think the channel rating tool may have a small quirk (or maybe I don't fully understand it?):

I fortunately operate the only AP on the 5 GHz band in range. I've set my OpenWrt router to spawn two SSIDs on the same radio, one which is my "main" SSID, then a guest SSID. Both SSIDs are obviously on the same channel, as they are provided by the same radio.

In this case WiFiAnalyzer should not recommend me to move to a different channel, as it should detect it's the same AP (same channel, same BSSID). But it seems to do so, as it always indicates the channel my AP is set to as "average" (yellow) or even "bad" (red), and shows "Best Channels: <all the channels I'm not using>".

Is that a corner-case you didn't consider?

Kind regards,

Ralf

Is there any particular reason why the project does not support Android 4.x? In particular, I have only one device (my cell phone) that has an Android that is newer than 4.

Is there anything that the program uses that is intrinsically only supported in newer Android versions or is it just a matter of convenience?

Thanks for making this great app available also on F-Droid!

Allow users to select country to show allowed channels

I'm not sure if this is available with root access though.

I don't know if this sounds as a good feature but it will be nice to have some zoom capabilities on the charts, especially on the tablet where is more area to view.
thank you!

If I try to install it through the android playstore website, it tells me that none of my devices can run/install this app.
What special requirements or android version does the app need/request?
I have a samsung galaxy ace 2 (adroid 4.4), and a xiami redmi note 2 (android 5.02), and samsung galaxy tab 2, and a blu dash 3.5.

Add channel bandwidth to each access point on the access points list.

In "Channel Rating" it would be nice if you could choose a WiFi AP that you would like to evaluate for best channel. Thus, so you don't have to be connected to the WiFi AP to find the best channel.

would you consider attaching the .apk file with your releases/ here on Github – so people running Google-free devices w/o Playstore access can grab your app? I'd then even offer to add it here, so your users can get updates automatically using the F-Droid client.

Thanks in advance!

Channel graph issues:

I noticed that pre 1.6.2 that a 2.4Ghz 40MHz SSID was displaying -1 channel of the actual and now on 1.6.2 it is -2 channels of the actual.

Thanks to https://github.com/arafey for pointing out that the extension channel is four channels lower or higher than the control channel.

arafey "A 40 MHz network wouldn't use 11+9. It would use 11+7. 9 is the center of the two channels. Some wireless APs will show 11+9 but they're telling you the primary channel and the center channel."

Channels 12 and 13 are not valid for Australia however show under "Available Channels" tab

Hi, I appreciate the amazing work you have done so far with the app,

I would suggest a small addition to the application:
On graph would be nice to have Access Point details.
When touching a specific chart, highlight and show details.

This application works very well, however, it needs to differentiate between 20/40/80/160 MHz channel widths in the graph. As of right now, a WiFi network operating on multiple channels will only show up as a 20 MHz network operating on the primary channel, which makes the auxiliary channels appear free although they're actually not.

Icon is very difficult to see depending on your screen background.
Add background color to the icon.

The current domain com.vrem.wifianalyzer (reversed) redirects to a hunting website which is awkward, considering what WiFi Analyzer is about.

At the moment you just need to many taps to switch between 2.4GHz and 5GHz. I counted and need 5 taps.
Here a suggestion that could reduce it to 3.

Inspiration via Transportr's sidebar where you can change public transport networks:

Here a quick and dirty mockup:

In the current implementation it could switch between 2.4 and 5 GHz but in the future if or when #48 is implemented it could enable/disable the frequencies separately.

If this was implemented the old settings option could be dropped because it is redundant.

It's difficult to match the color line in the legend to the item in the graph.

Is it technically possible to add a noise floor measurement?

improve scan cache handling

Allow scan intervals from 1 second instead 5 seconds

This is just a copy of my review on the Play Store. Let me know if you need any extra information.

Graph Legend font is too small, nearly impossible to read.

Add settings options to display/hide series title per graph
Channel graph series title - default display true
Time graph series title - default display false

Allow user to select first menu item at the application start up

Show true access point channel width.
This is possible only for Android 6+ (APK 23+)

By touching application toolbar switch between 2.4 & 5

Show only channels allowed in locale

In the dark theme some colors are not clearly visible as in the light theme.

Enhance channel graph 5GHZ navigation.
By Page? or some other way.
Too much scrolling

On channel graph add series title above specific chart

Display current country locale and channels allowed

When I perform this sequence of events, the scroll view on screen goes back to the top:

1. Open Side Drawer
2. Click on About
3. Scroll Down
4. Orientation Change

Travis CI integration

On some devices (this one is a MotoG (3rd Gen) ) the IP address gets squashed along the right side of screen, completely breaking the UI.

Two screenshots attached: https://goo.gl/photos/f3XNGhsfbce94Dv89

Switch to new version of GraphView 4.2.X

Please make an option to connect/disconnect from the selected WiFi network.

In Time Graph section, It would be great to highlight or make otherwise obvious to which AP is my device connected. It could be used to monitor handovers between APs based on signal strength. (Wifi Insight app does it in a nice way).
Thanks guys!

Add ability to export/email access points list

Some users running Android OS 6+ (Marshmallow) have reported that the location service must be enabled for the application to see WiFi networks. Marshmallow users may need to turn on the location service, even though WiFi Analyzer does not explicitly require it. This appears to be attributed to a potential issue in Android OS 6+ that requires location service in order to see WiFi networks.

Running gradle clean updates version information. I don't think that is supposed to happen?

Show more channels per page.

Toggle WiFi band in application toolbar reload application to initial state.

Is it possible to see all 2.4/5 GHz APs on the list simultaneously without switching band?
There is another "WiFi Analyzer" in the Play which can do it.

Also, it would be great to group visually several APs not just with the same SSID, but which are used in corporative network as one virtual AP (i.e. with transparent routing).
