[Q] Slow speed on WiFi - Galaxy S III Q&A, Help & Troubleshooting

Slow speed on WiFi
Hi, having some issues with my wifi connection. It usually tries to reach the slowest speed on the wifi link based on the usage. For example: when I turn on the wifi it connects at 120mb on wifi n, then it starts slowing down the speed down to 1 mb if I open the browser it goes up to 6mb but thats the max speed that it goes but on the real internet speed is about 3mb.
I alreday tried disabling the energy saving option with *#0011# but nothing changed.
My phone is stock with xxell4. It's from the baltic (seb) but I'm using it in Mexico. My internet is a 20 mb connection via fiber optic and the router isthe huawei hg8245
Do you think that flashing a different modem or changing to a custom rom would help?
Thanks and regards

Modem has nothing to do with WiFi that's a kernel swap to try .

Well just for the record I flashed the ella modem and both wifi and cellphone signal were improved, maybe its a placebo but the tests that I have done show better speed on wifi, still not reaching 20 mb but I'm getting over 10 mb

[Q] changing wifi speed?

hi, noob here.... I checked the forum and didnt see an answer so thougt i would post. I have a wifi connection capable of much faster speeds than my tab is connecting. Can anyone tell me how to change the wifi speed setting? Thanks
Good question, I don't see a setting anywhere for that option.
you mean the same as changing MTU for network cards on a PC? what does your LAN speed test show? For my SGS1, the wifi speeds and the time it takes to connect to a network differs from which modem I use.
I think OP means wi-fi link speed, e.g. 11mbps, 54, 150 or 300mbps. My 11n router doesn't show what speed my tab is connected as and it appears there is no information on tab either. But whatever link speed it is, it will be much faster than my internet connection speed anyway. So it really doesn't matter for me personally. If you use Wi-Fi Kies or other app to download video files from your LAN, it may make some small difference. I'm sure the default is a balance between speed and battery consumption.

Yes that is what i meant.... My tablet connects at 65mbps but my router goes up to 300mbps. I was hoping to link up faster but i dont see a setting for that...

Slow Wi-Fi download speeds?

Has anyone run into slow Wi-Fi download speeds? Speedtest which reports accurate results on my laptop running over Wi-Fi only reaches around 3-4MBit download speeds (Should be around 30MBit) but upload reports fine at 8MBit. It's not just a problem with speedtest and can also be noticed when actually downloading updates/game files. Wi-Fi settings reports a connection of 65MBit but shouldn't this be 130MBit (As laptop reports) when connecting via N Wi-Fi?
Any ideas?
Edit: Seems that channels were at fault, I changed it to auto and the speeds are now respective of the actual connection

ViperX+ tweaks

What does "wifi n force tweak" mean? Is there a toggle or what?

Standard WIFI speed is 54 Mbps for 802.11g standard, if you have WIFI N enabled router (2,4/5 GHz), you phone can connect with a bit higher speed of 65 Mbps or 72 Mbps .
But some operators in some country disable WIFI N support, so this tweak will force enable it back.
You can toggle it inside tweaks under "Misc" tab.

My modem does not support N wifi so how do I know if my operator disable Wifi N support on my phone?

Simple, try to connect to any WIFI N modem
Also, you dont need to bother about it, 95% of users have no benefit from WIFI N, you dont have that fast internet, even if you do, phone cant process that much data...
battery drainage
Won't the battery drain faster because of the higher speed?

Slow Network with 3G - H

I found out, if i have bad Network, the Phone stays in it. For example, at work i have a Zone were only "H" is available and very slow. Phone shows 3G and i have 15KB/s DL Speed, wich is not really usable.
If i move to a Zone were it is better Network, it still stays in "H" and i still have only 15KB/s DL speed. But, if i set my Phone in flight mode and back, then i have "H+" (Phone shows still 3G - wich is normal) and DL Speed increases to over 4-5 MB/s and more...
I think there´s a problem with Network Selection, so Phone does not immedialy take the fastest Network, it stays in slow until the user makes a manually reconnect with flight mode of on or like you described with choice of Networks.
This is really disturbing, because at work i always have to set flight mode on and off and wait till connection and then its possible to surf in the internet etc..... before its so slow that you wouldn´t really enjoy surfing in the internet...
Anyone has a solution or a fix for this?
Its really annoying all times to switch flightmode to have usable internet...
No Idea anybody or a tweak?

Slow WIFI and DNS

Compared to my browsing speed on tmobile's network which is very fast, if I switch to wifi it becomes very slow in loading a website with any browser.
For example It takes up to 30 seconds to load espn.com, seemingly spending half that time looking up the DNS, and then slowly loading the whole site.
Once I am on a site, browsing within that site is fast and I have a good signal and connection.
I don't have the same problem with my other devices on the same wifi so It can't be a problem with my wifi.
Deactivating Adguard does speed up the site loading on wifi somewhat but it is still much slower than on my data connection.
Just tested this myself. Loading espn.com (via Chrome) takes appr. 2 sec. from requesting the page until it is fully loaded. Access via relatively slow company WiFi (100 - 120 MBit/s).
If you've tested with different WiFis I expect it is still a (mis-)configuration problem and/or an app you've installed on the phone.
I changed my DNS to OpenDNS which made a dramatic difference ....so it looks like it is the [email protected] att dns service that's to blame
