[Q] Restricting wi-fi to connect at 802.11g ONLY

Is it possible ? I have been disappointed with the browsing speed on my TP2 and thought it might be something to do with MTU settings or something like this. However, last weekend I decided to change my router mode from 801.11b/g to 801.11g only. WOW, suddenly my browsing was perfect (the same speed as browsing with my laptop)
So I wondered if it's possible to set something on the TP2 to allow it to connect at g Only - for when using in areas which have a Free Hotspot (like Cafe's or Hotels), since I cannot control the speed that they allow me to connect at.
It's very possible that my TP2 was connecting originally at g speed but that rates were in some way competing against each other.

WM will normally default your connection to the better of the two choices. If the option is between b or g, the connection would default to g. There are some things that could be affecting your connection, however. This is most likely a problem with your router broadcasting both signals at once. If you have no use for a b channel, then have it simply focus on sending the g channel.

This is exactly what I have done - shut down the b channel. However, I am trying to ensure that I connect with g ONLY whenever I find a Hotspot in public places.

Maybe the problem with browsing speed isn't your phone!
Better check if you are in an area with lots of wireless networks... Try to set your router to use a channel which is 3 channels distance from other WiFi networks.
For example if you have networks on channels 1,3,5,11 you should set your router to use channel 8.
Also try to set "802.11G Protection" to ON, if your router has it!

Any solution? (I know it's old, but I also want to restrict to 801.11g on my android tablet only and I have found nothing on the internet).

The issue is not with the phone in this case, but the access point. When running in mixed mode, data transfer speeds on wifi access points slow down unless they have multiple dedicated radios. If you want the faster wifi speed, just don't use 802.11b. It's antiquated anyway, especially considering we now have not only g, but n and ac standards on the 802.11 rfc.

i've noticed, however, my phone's (samsumg g-s5) battery drains much quicker when connected to 802.11n network compared to 802.11g. there is no real need for more than 54 Mb/s on my phone, but on my laptop there is. therefore, a way to restrict the phone to use only 802.11g in a mixed-network environment would be beneficial.

As far as I know, you can only restrict the mode of the access point, not the phone. I have yet to see any wireless client device, in fact, that lets me restrict which radio mode it uses, save perhaps some homebrew stuff running embedded linux.
EDIT: Pardon the grave-dig. I had been off the site for a while and only just noticed the above reply to my posting from last year after having last night posted a question of my own.

[Q] 802.11n?

I read that the Desire HD has 802.11n but when I've created a WiFi Hotspot it shows a 802.11g while most of the other networks around me are clearly shown as 802.11n.
Does the Desire HD lack 802.11n? Or does the WiFi Hotspot disable it?

I would say that when DHD is acting as a wifi router it doesn't have the capability (or it's disabled) to broadcast a 802.11n network but it can definitely connect to a 802.11n network.

Can you confirm that it does indeed only run as 802.11g when acting as a Hotspot? (Each WiFi adapter I have is the same so I'm wondering if its a issue with my adapters)
Also I see no reason why they'd limit this, my DHD is my router and I'd love to have much better WiFi speeds on LAN transfers!

Wifi cuts out when bluetooth is in use

Whenever I have both bluetooth enabled (and paired with any device) and wifi enabled, and I'm streaming music (Spotify in my case), after several minutes (almost randomly), the internet will stop working. Meaning, the WiFi icon will still show as connected, but it can't connect to anything online. I typically have to disable and re-enable WiFi for it to work, but then it would do the same thing again.
The strange thing is, my Galaxy S4 had the exact same issue/behavior. On both devices, I've seen this behavior regardless of the type of WiFi connection and/or bluetooth device (I've noticed it with my skullcandy headphones as well as my Sync in my car).
Do these devices share the same bluetooth/wireless chipset? Is it an Android thing? I'm forced to either use 4G with bluetooth, or WiFi with wired headphones. Thanks.
EDIT: this is using 5ghz Wifi.

What version of android are you on ?
carrier phone or unlocked. Some times these issues are carrier specific and non existent on others.
If you go into settings - wifi
Uncheck any option that says switch to data if wifi is unavailable.

I can confirm that this is an issue, I experience the same problem on my g4 818p

WiFi goes on 2.4ghz or 5ghz(most commonly on 2.4ghz) Bluetooth works on 2.4ghz. Unless you are 1m from router, BT is going to butcher your wlan. Had the same problem before. Solved it by buying dual band modem-router.
You could forcing different channel in wlan settings.

http://smallbusiness.chron.com/fix-bluetooth-wifi-interference-71008.html
idea here is reducing interference to bluetooth from competing sources.
- switch off wifi and use data which the OP is doing. Curious that the problems occur even at 5Ghz. Would have thought that band would be relatively immune to 2.4ghz sources.
- reduce the distance between bluetooth device and phone.
- move away from any sources of wifi interference if wanting to use bluetooth.
And now from the ppposite direction. Preventing bluetooth from interfering with wifi

Read the comments below. similar to the OP.
The key is more management of the problem rather than solution.

I'm using the Verizon variant.

this issue hunted me on all software version
Many options live
Router: Try another chanel
Router: Try only 2.4 or 5 Ghz
Router: Try only N or try only b/g/n mixed
App: Delete tunin radio
Last options send back service mainboard change.

i m facing the same problem but only when i do cellular call,
i am using realme wireless earphone , when i used to call my wifi speed gradually decrease , and after that stop working completely..,
after disconnecting the call i need to OFF and ON to work wifi again....,

My wife got the same issue with a Samsung A40 (and before with a Motorola), when using 2.4 wifi and Bluetooth connections (band and speaker for instance) the wifi is hanging. With wifi 5 it's ok. I don't have any issue with my phone using same network. It's crazy.

App That You Select 2.5ghz Vs 5ghz WiFi Frequency? Constant WiFi Authentication Issue

I am looking for an app that lets me control what frequency my phone uses for WiFi.
Alright....I am so sick and tired of all the issues I get with WiFi on my Nexus 5x. It seems like every new build I get more and more issues. Stock, Pure Nexus, and RR Roms have all given me issues.
I know that this was an option in the WiFi settings pre-Android 6.0. With how many issues with WiFi has been present in N and M, I have read that controlling what frequency has helped other people.
With the removal of the WiFi frequency option the updated WiFi code is going to try and secure the best connection. The problem with that is my Nexus 5ghz doesn't like connecting to 5ghz. The issue is that my works router has multiple Access Points that broadcast in 2.5ghz and 5ghz. My phone won't stay connected to WiFi because it connects to a 2.5 and then goes to a 5ghz thinking it is a better connection

Dual Wifi? 2,4GHz and 5GHz at the same time?

Hi, Can RN8pro connect on two Wifi bands at the same time? It should support dual band, but in some review is was not working.
And what maximum speeds do you have on wifi connection?

Not at the same time, I've had many phones with 2.4 and 5ghz and none have supported both conections at the same time, my speed for the 2.4ghz my RN8Pro gets a link of 86mbps, and for the 5ghz network the link is 433mbps, but I don't know if the 433mbps is the max speed that the phone allows or if the router is the one that is limiting my connection.
EDIT: However if you configure your 2.4ghz&5ghz networks with the same SSID and password in the router, when you connect to the wifi, your phone based in the signal will switch between 2.4 and 5ghz automatically.

Well Realme phones can connest on more bands of same wifi. RN8pro should be also able, but on TechTablets sad that i was not possible for some reason. I am asking if anything change with new ROM?
RN8pro shoul have also X antenas for wifi and some other tools.

In reviews, it was stated that the note 8 pro was able to connect 2 wifi connections at once. Is that true and how do you do you that?

Redmi Note 8 Pro should have Dual simultaneous wireless network, but it is disabled in software!
Realme X2 has doble speeds in Wifi. Can dovelopers unlock it on RN8pro?
