I'm setting up my newly purchased S9+ and I'm wondering about the "APN protocol" settings which, by default, is set to IPv4. I found some discussion on that in other threads and I tested both settings: IPv4 - only and IPv4/IPv6. Not knowing much about it I might be biased(placebo effect) but I thing I'm getting just a little bit stronger signals(wifi & cell) around a different places at home as shown by 'Network Cell Info Lite' app when I set it to ipv4/ipv6. Looking for a good explanation to a question: is there any merit in that, setting it for ipv4/6?
I am wondering the exact same thing ...
I noticed on Tmobile Community ...some recommend IVp4/IVp6 ....some say IVp6.
I am trying to test dual stacking on Metro PCS /Tmobile but only amateur trial and error .
I wonder IF it gives a slightly 'wider ' footprint on Web.
I wonder IF it gives a 'wider ' bandwidth in transmission and reception for the Device -and consumes slightly more power ?
Meaning - is it like a transceiver transmitting and receiving on two channels at once [or wider bandwith on one channel ] ?
I am not a Dev....so keep answer simple or include a summary -,thanks .?

I found an answer, my phone is set on IPv6 connection through the router settings. I don't have the S9+ anymore so, the details to enable IPv6 are here:

Odd, IPV4 vs IPV6 should make no difference on your signal strength. It's just the IP Address version being used.

Just a reminder to get it on top of the list again
It is becoming rather difficult to compare all the different statements about Wifi performance and the speed results determined with Speedtest.Net
Don't use the bars at the bottom of the screen.
These are just a graphical image representing that something is going on with Wifi. If the parameters in the firmware are changed you can get as much bars as you want.
Furthermore the bars don't say anything about the quality of the Wifi connection.
Don't use Speedtest.Net
Speedtest.Net doesn't measure Wifi speed but the speed of the connection you are having with a remote Speedtest.Net server on the internet. The speed it indicates is the speed of the weakest link in the routing. So congestion on the internet (not your Wifi) is represented in a slower speed.
When your family or housemates are streaming Youtube the speed it indicates is the speed for the remainder of the bandwith that is left over for you.
Use only Iperf!!! (it's free)
With Iperf you set up a server and a client in your home network . By executing Iperf with different parameters you can get a lot of different info about your Wifi like bandwith, lost packets, jitter, sent and recieved data, etcetera.
For the noob it seems complicated but it isn't. There is a good tutorial on http://openmaniak.com/iperf.php
Please do me, the community and yourself a favor.
Use Iperf.
That way we can get data we can compare.
And maybe someday it will get us somewhere
Thank you very much in advance
PS: Don't just do one test. Do multiple tests. This is something you can automate with Iperf. Set it to do 20 (or more) tests and get some coffee.
using -c<ip> -d I get the following in the same room of my 300mbps wireless n router:
Client connecting to 192.168.1.100, TCP port 5001
TCP window size: 8.00 KByte (default)
------------------------------------------------------------
[256] local 192.168.1.102 port 49792 connected with 192.168.1.100 port 5001
[ ID] Interval Transfer Bandwidth
[256] 0.0-10.0 sec 8.52 MBytes 7.13 Mbits/sec
[280] 0.0-10.1 sec 36.1 MBytes 30.1 Mbits/sec
[288] local 192.168.1.102 port 5001 connected with 192.168.1.100 port 58706
i'm going to assume that this is bad...
Edit: Another test doing -t 25 -i 1:
I get an average transfer of about 4.4 MBytes and Bandwidth of an average of about 38MBits/sec

Lot's of people asking the same question
Guys,
What {protocol : port}s need to be open for WiFi calling to work?
I can see on my home router:
TCP:any -> TCP:5061 - to register with WiFi calling server
UDP:any [high port]-> UDP:any [high port] – to place a call
I’m complete newbie on WiFi calling (and many other things).
Does anything else need to be opened?
Anyway to configure WiFi calling to use some shorter UDP range?
Not everybody is comfortable with opening whole UDP high port range, even if it’s for outgoing & single IP only…
If it’s relevant, I’m on 1.43.531.3
To mod: I did search forums, but there is nothing about exact ports for WiFi calling…
Ports can be whatever you set them to be. It shouldn't matter if your phone is already connected to your home network though

Another alternative you can do is set up a static IP for your phone. Make sure you set a IP address that is a bit higher, such as 192.168.0.30 (this is only an example). You want it to be a bit high so DHCP won't accidentally assign the same IP to someone else that you already have. After that, just put your entire phone in DMZ in router settings. Meaning, it would make your phone (with the specific IP address) wide open to the internet, not anyone else.
ALSO, from what I've looked, you will have to open up UDP port 500 and UDP 4500. You don't need to create a range, but just set an individual rule to allow these ports.
Hi, I wonder if it's possible to force a manual specified mobile data connection to be used.
e.g.
I tell the App that it should force "G" to be used instead "E" even if edge would've a better signal strength. because sometimes I am able to have "G" as data connection with 2or3 from 4 stripes but it switches randomly between "g" and "e" and "edge" has most of the time 4 of 4 stripes.
I just don't get the unnecessary switching between the two GSM data connection types. it's unnecessarily annoying because it's also stop the data transfer. it just su**
especially Samsung devices do a lot of unnecessary mobile data connection switching
we already can force between GSM and WCDMA. but we should be able to force within the different GSM data connections too.
so, would it be possible to code such an app? or is there something like that already available somewhere? did a lot of Google research but I end up with no results.
well, I can understand that this would be some sort of lower priority mod/app but whoever can effort the time and has the skills to write such an application could add the complete set of option to it.
- switch between e, G, H, LTE etc.
- set times when which data connection should be in use
- tell the App to use only GSM when the overall traffic is near a specified amount of data.
- a watch dog for established connections would be nice to and some sort of firewall to deny connections or other way around to have to specifically allow every connection
I have a 5GB high-speed data plan. and I would like to swap automatically to GSM only once I wasted 4GB of it to save a few bytes when I really need full speed.
I am not sure. maybe such a tool is kinda pointless on a smartphone but I would love to see such a tool.
thanks for the read
regards
Hello, I stumbled upon this app but I can not find more information about it.
Was wondering if someone could check into it. Main goal for this is to get better performance out of the wifi, but im not sure if it's good or bad.
If anyone uses it please let me know
Here's the link to the app:

Don't even think about doing so!
A maximum transmission unit (MTU) is the largest size packet or frame, specified in octets (eight-bit bytes), that can be sent in a packet- or frame-based network for example Internet. The Internet's Transmission Control Protocol (TCP) uses the MTU to determine the maximum size of each packet in any transmission. Too large an MTU size may mean retransmissions if the packet encounters a router that can't handle that large a packet. Too small an MTU size means relatively more header overhead and more acknowledgements that have to be sent and handled. Most computer operating systems provide a default MTU value that is suitable for most users. In general, Internet users should follow the advice of their Internet service provider (ISP) about whether to change the default value and what to change it to.
If you do so your normal Wifi range might get tweaked leading serious issues such as frequent wifi disconnects, no connection, may result in loss of the Wifi Direct Feature.
Phone may be soft bricked and phone may reboot every time any wifi network is availble. I suggest don't use this app until you are a developer!
Wifi range or speed can't be increased by any app. It depends upon hardware. Wifi a/b/g/n is usually faster than Wifi b/g/n so prefer buying a new device rather than using this app. It is purposely for developers.

Question: Is there a way to modify Android WiFi settings, even if rooting is required, such that the radio ignores all channels but one, say 165 in the 5ghz WiFi spectrum?
I know there is a way to limit the channels for a radio because this must be done for each country. I was just wondering if there is a way to augment the country specific settings by eliminating even more channels. The reason I would like to do this is to take an Android TV stick with Miracast Sink capability and limit the channels to one that is unused in my environment without relying on some sort of network negotiation. We have a wireless network that is quite dense and it seems to bog-down Miracast solutions. One like the Netgear PTV 3000 works fine at home but is really flakey at work. Also, the wireless network guys and security gurus don't like the idea of a wireless device that can't be tuned. This is just an attempt to remove one hurdle. Another hurdle would be to reduce the power setting of each radio but the channel selection is the most important.
