Title: Trouble with WiFI with one SSID, but multiple transmitters ? Android issue ?
Post by: Dixit on September 30, 2018, 09:48:10 am
Hello forum members,

The Gemini is not very strong in receiving WiFI signals, but it becomes particularly troublesome when it needs to capture and hold a signal with the same SSID name, but multiple transmitters. Examples are:

- Free networks in the city, such as Antwerp Free Wifi
- Hotel WiFi
- The WiFi hotspots offered by my provider and transmitted by the other clients throughout Belgium, all known as "Telenet WiFree".

The Gemini's behaviour is the same. It shows a strong signal, but refuses to connect. Or worse: it has a connection and suddenly entirely looses it.

I think it accidentally switches over to another transmitter, but with a weaker signal. It then looses the signal.

Is this an Android thingy ? Is this a Gemini thingy ? Can it be improved somewhere in the advanced settings ?
My wife has Android 8 and does not have this problem.

Have you Googled "wifi boost app android"?

I see several WiFi boosting apps from Play Store, Android Authority and others designed to resolve that wobbly WiFi signal situation.

Cheers!

Another two cents: I assume you got the full boosted (Wifi+GSM) model and you got a data plan, which you never switch off. If Wifi is weak your Gemini starts to search for GSM-data, before deciding to switch back to Wifi. This kills any transfer speed . To alter this behavior open "Settings", open "Developer options" (if you can't find it open"About phone", tap on "Build number 7 times", go back one time and you should see the additional menu entry), scroll down to "Aggressive Wi-Fi to Mobile handover" and then to "Mobile data always active" and activate both. The third possibility is to alter Wi-Fi roam Scans. Please report back if it made your Gemini flying.

Hope that helps, bye for now Fred

Yes, it is an Android "problem". The issue is that you cannot select access point,  at least using stock Android GUI. I am having the same problem with UPC Wi-Free, where there is a limit of 5 clients per AP, but anyway the whole network is completely borked, with long periods of outages, misconfigured routes etc., and selecting an appropriate (working) AP often helps - under Linux, using the bssid directive under wpa_supplicant.conf, but seems to be nearly impossible under Android (the API to configure specific BSSID has been even removed in Android 8.0: https://developer.android.com/reference/and...n.html#priority (https://developer.android.com/reference/android/net/wifi/WifiConfiguration.html#priority) ).

Thanks for the confirmation, Radovan.

Though I read your message as "Problem confirmed. No solution."

Indeed, Telenet Wifree is the sister net of UPC and the quality throughout is doubtful. Same here.

Update after 2 something years: after thoroughly unpleasant experience with the UPC's customer service, like *completely* ignoring my reports for months until *I wrote a f*ing paper letter to them*, then asking several times for some details that I already provided them and ignoring my replies and asking the same details again and again, finally under pressure confirming they've received my previous e-mails (but apparently not reading them), and then... nothing happened for months. (sorry for the rant)

And then, suddenly, Wifree started to work and keeps working for maybe half a year by now, after almost 2 years of not working. Not that I need it that much, and I certainly *do not* recommend UPC if you have a reasonable other choice. And it does not solve the Android unable to select an AP issue.
