Only minus are the ads This is the original WiFi analysis app. Super good and a top recommendation despite ads. I hadn't notice it even does recommended channels but I would just eyeball it in the past. But I'm now actually leaning toward other open source app because obviously no ads but it also graphs plateaus rather than arches which emphasises 'strength' rather than 'width' and so doesn't conflate the two -- a really strong signal arch may appear wide or like 2 channels.
Great tool The ability to see which wifi channels are most crowded is awesome, but the real gem is the app's ability to detect the optimal channel for your wifi hotspot. It's not always 100% accurate, since Android's hardware can only detect how many routers are on each channel, not individual devices, but the app does a wonderful job estimating. It's thanks to this app that I was able to fix the low signal in my back bedroom. Some neighbor's using channel 4, making 1 & 6 cut out there for my router.
Does what it should very well! However, when using 2.4ghz you should stick to channels 1, 6 and 11 in all but the least congested locations - overlapping signals is *worse* than sharing the same channel with other SSIDs. Floating between 1, 6 and 11 is antisocial, causing everyone more problems. Developers should highlight this in the interface.
Awesome app This app is great. I tell people to download it all the time. I work for a tech support group for a big communication company, that will remain nameless, and it is so helpful it showing the average user what wifi interference looks like and how it can be prevented. My only gripe is it's not on iOS because I can't tell the customers using iPhones to get it!
Lazy developers What's new? "Bug fix". I am not sure i can trust developers who are so lazy they couldn't be arsed to tell the users what changes they just made to their phones... "It's a bug fix, that's all you need to know peasants". Stay classy dev..
No support for multi-SSID routers. Has no support at all for multiple wireless networks that are managed by the same router. Could not figure how to tell it that 2/3/4 networks (all with different SSIDs and MACs) are actually managed by the same hardware and radio chip. Keeps suggesting me to change the channel because the current one is already in use by others that broadcast at similar power levels... WTF, really, Sherlock?... it's the same radio chipset so the router cannot use different frequencies for the different SSIDs.
