[Q] G2X and Wireless N

Has anyone been able to successfully connect to 802.11n? I have a Cisco Linksys E3000 Advanced Dual-Band Wireless-N Router and my laptop connects to N without issue. My G2x has no issue finding my G band and connecting to it, but the N isn't even detected. I'm not filtering by MAC address and the N band has plenty of ip's available in the DHCP pool. Additionally, Other devices can connect to the N band without issue. I saw someone had mentioned something about wireless N previously, but I can't find the post anymore.

I am the one having this issue also, but mine is with my dual band Time Capsule..Is there a setting somewhere how to activate the N on our phones?????

bueller? I'm just Curious. Seems we both are using Dual band routers. Anyone running strait 802.11n at home or the office?

Mine only saw my G band, not the N on my dual-band Linksys.

i am and its connected and blazing fast good luck guys belkin

I just double checked a few spec sheets, just to make sure, but this is what they all say...
Connectivity
Bluetooth:Yes
Wi-Fi: Yes (802.11b, 802.11g, 802.11n)
So I'm fairly certain I'm not all hopped up on crazy pills like Mugatu. Is it possible this feature is disabled like the FM radio?

working here - dlink dir655 connected over N.

Wireless N works perfect here, using, umm, no idea what router my office uses

I'm able to connect to wireless n router also a dlink.

nope its not picking up my wireless N band on my dual router (vizio), I think its more a froyo thing than anything
my mytouch wouldnt pick it up either, until I ran 2.3.3

Mine won't connect when I set my wifi (asus rt-n12 w/ dd-wrt) to wireless-n only. My nexus one had no problems with this.

I have a Netgear WNR3500L and set to 300Mbps.
Phone can only connect up to 72Mbps.

I have a Cisco/Linksys WRT400N and all the phones (Nexus One-Super AOSP 2.3.3, G2-CM7 Nightly #40 2.3.3 and G2X Rooted Froyo 2.2.2) connect fine. Only when I was changing kernels or something did I ever have an issue.

At most our phones can theoreticaly connect at 150 mbps, to do more than that you have to have dual band antenas inside of the phone which I don't know if there are any phones that even do that.

The phone does only 2.4 ghz N not 5 ghz N so check your routers to see what bands its using. Also 5 ghz N can go up to 300 mbps and 2.4 ghz N only goes up to 120 i believe.

It definitely supports N. I have a dual band router and my 2.4ghz radio was running 802.11G/802.11N and my G2X in Speedtest would hit 30mbps down and 20mbps up.
With JUST 802.11G the G2X maxes at 15mbps down and 10mbps up.
I've left the radio on 802.11G since it for some reason seems to take less battery and 15mbps is good enough for me right now

I'm connecting to my DIR 655 with no problems. What is everyone using to see what speed it's connecting at and whether it's connecting through B,G or N. I am showing a link speed of 65 mbps under network settings.

Linksys Dual Band N Router
Hmmm, I was looking up a problem I am having connecting to my Linksys Wireless N router and found this thread.
I am having the same issue... Can't connect at home over N, but connect at work over G with no issues.
Also I called TMobile a few days ago (had to return my original phone for another problem), but when we were trying to troubleshoot and I mentioned I had problems connecting at home, he asked if I had a Linksys wireless N router. I didn't think about it at the time until I saw this...
UPDATE:
Nothing I tried in these forums worked for me but I tell you what did. Using my old D-Link b, g router. Set this up and connected in no time, no disconnecting, no issues.

Working For me - fix is here
I had the same problem.
It wont show 5ghz / n by default.
First goto settings>wifi settings screen . click on menu and click advanced settings > Uncheck the wifi optimization.
And then scan networks. you should be able to find your n network.

P5100 a/b/g/n - Can't see my home 5Ghz network

The specs indicate that the Galaxy Tab 2 10.1 has a/b/g/n capability.
Why is it that mine doesn't see my home N (5Ghz) network? (the router is broadcasting the SSID and I can connect with other devices)
Anyone else experience this? or know the reasoning?
Thanks.

Why don't you try to change that wifi router?

802.11 N can use 2.4 Ghz and 5 Ghz (depend on hardware spec), and usually 5 Ghz spectrum are used in some high end / outdoor router. Almost all smartphone and handheld device use standard 2.4 Ghz, so you can set your router to use 2.4 Ghz and "n" network.

Ah.. I see. This must be it. My network is certainly set to 5Ghz. It's interesting to note that my older Atrix can see the 5Ghz network, but the Tab 2 cannot.

its because 5ghz was thought to be the next band standard but it didnt catch on as intended

Does Yu Yuphoria support wireless on 5GHz band ?

Hello all,
I searched everywhere but I couldn't find a straight answer for this issue. Does this phone support wireless ( Wi-Fi ) on the 5 GHz band ?
I don't care if it is 802.11n or 802.11ac standard but does it detect a wireless router running on the 5 GHz frequencies ?
Anybody who has a dual band router can test this out and see if the 5 GHz network is also seen or not.
I have a router which only works on 5 GHz ( single band ) so I want to buy this phone but I want to know if it will work otherwise I will look for something else.
Thank you in advance !!!

Nobody has 5 GHz wireless network near them to check ?

Thank you for helping out ! I look forward to your response.

Man,
I forgot how to check in the router for 2ghz and 5ghz wifi bands...
My router is showing the channels to be used only.... and wifi bgn ...
How do i check the 5ghz ??
I know i've read about this somewhere but cant recollect it now...
If you reply, then maybe i can check now since i am at home...

What model of router do you have ?
Change the SSID to be different for the 2.4 GHz radio and for the 5 GHz radio.
For example : name 2.4 GHz network like "MyNet24" and the 5 GHz network like "MyNet5" etc.
And if your phone can see both "MyNet24" and "MyNet5" then it is dual band and I have confirmed it.
Or you can use https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer&hl=en to check it !

Ok.. DIdnt understand anything much about making 2 ssid's so i used the app...
the app shows me 2.4 and 5 ghz channels... and in 2.4 all are ticked.... whereas in 5ghz a few are ticked...
channels in 5ghz
161 (5805 mhz)
157 (5785 mhz)
153 (5765 mhz)
149 (5745 mhz)
48 (5240 mhz)
44 (5220 mhz)
40 (5200 mhz)
36 (5810 mhz)
so i deselected 2.4 ghz channels and tried.... doesnt allow me to deselect all...
i have a TPLINK wr740n router.
tell me how to check more,,, or if this helps you..
Edit : in the wifi settings of the router i have only 2 channel widths 20 mhz and 40 mhz...and channels available are from 1 to 13.
I've kept both on auto... this i know i can change to a particular channel or even a channel width,, but i just let it be because my last router got screwed trying
to fix something in dd-wrt

Slow WiFi when connected to Bluetooth?

Hello guys !
As mentioned in the title, I am getting very slow WiFi speeds when being connected to Bluetooth.
I tried flash the factory image but the issue is still there. I am on the latest security patch.
Thank you
Henry

Is this happening while connected on a 2.4GHz or 5Ghz wifi network?

noticed the same when I updaded the OS of all my Google Pixels, Bluetooth is enabled and the speed on a 5GHZ Wifi was super slow. Took ages to download 500 MB while I have a 400 Mbit connection.

bluetooth operates on the 2.4GHz spectrum and can sometimes affect your wifi performance if connected on a 2.4GHz network. if your router supports 5GHz, try connecting to that and see if your wifi performance improves. if your router doesn't support 5GHz, try changing the channel in your router settings until you find a channel that offers the best wifi performance.

Help getting wifi 5ghz

Hello.
I an having an issue with my sm-g955fd phone. I need to use the 5ghz frecuency for wifi and I can't seem to make it work. Flashed Renovate Ice 9.5 and tried many different csc's but none enables 5ghz wifi. If anyone could point me to which custom rom to flash or csc to try. I would be most greatful forever.
Thanks in advance.

How's 5ghz work when on stock OS?

Does it support the 5ghz wifi (hardware wise)?
I know most devices are still on the 2.5 or 2.4 (don't know exactly which).

Yes of course it does. All Samsung phones have used 5GHz for years.
If there is a problem getting an S8 to work then it's either a (rare) fault, or due to the custom ROM.

5ghz didnt work either on stock rom. That's why i first tried changing it to a custom rom.

I think so. But i may be wrong. The model is sm-g955fd. How can I tell if the hardware supports 5ghz?

All S8/S8+ variants include support for 5 GHz WiFi. Are you sure you have properly set up your AP? Does the 5G connection work with some of your other devices? Try getting closer to the AP. If it does not work by then, it is likely a hardware fault.

I have tried with different devices and AP's. The phone doesnt pick the ssid of any of them.

As others have stated Samsung phones and other makes of high end phones have supported
2.4GHz and 5GHz wi fi for several years.
Although I wouldn't expect your problem to be caused by a custom Rom else other users of the ROM would likely have reported the problem , I would suggest putting a standard official Samsung rom on your phone at least until you get your wi fi functionality.
I would suggest a free play store app like wi fi analyser to easily determine which wi fi signals are seen by your S8+
https://play.google.com/store/apps/details?id=com.farproc.wifi.analyzer
Also be aware when you do get 5GHz working you will notice higher data bandwidth than with 2.4Ghz but less range from your router to your phone before signal drop out.

I did some research and on gsmarena I found that Galaxy S8+ uses the Wi-Fi 802.11 (https://www.gsmarena.com/samsung_galaxy_s8+-8523.php)
Went on Wikipedia and it seems that this 802.11 support communication in the 900 MHz and 2.4, 3.6, 5, and 60 GHz frequency bands. (https://en.wikipedia.org/wiki/IEEE_802.11)
Also, I checked my home network and the router is working both on 2.4 and 5, however, the 5 (which is set as another network) can't be used y any device (no laptop or smartphone).
I don't want to create confusion here, but it seems this 5ghz frequency is not as usual as the 2.4 one. And by checking my Internet connection speed on the 2.4ghz frequncy, it looks like there is no advantage of using the 5 frequency (my Internet speed on wifi is close to the Internet speed via Lan cable).

802.11 has a large number of subcategories
802.11a
802.11b
802.11n
802.11ac
and a vast number of others.
These have different frequency allocations and different channel bandwidth.
I could have explained better that in some cases 2.4Ghz will give adequate throughput (at or close to your internet speed)
802.11g is a 2.4Ghz standard with maximum of 54Mbps
However if internet speed is much higher as in my case then I get benefits from using
802.11ac 5GHz standard with single link bandwidth up to 500Mbps.
I would agree that wi fi using 5GHz probably not as common usage as 2.4Ghz which can have additional benefits as less potential for interference from nearby wi fi that uses same frequency range

I use 5G all the time..have high speed internet so see big diff. Since you say none of your devices can connect to 5G, you should play around with channel used..know there is a diff between US and Europe and channels used.
If you see same speed from reg wifi and hardwired lan line..5G will not make a diff.

Thanks to everyone i deffinitely cant get it to work. The reason I need 5ghz is cause i am using a slinstudio device wich works only on 5ghz frecuency and i cant connect to it. So i tried other 5ghz networks and found that i cant connect either. I guess i will have to change phones or something but its a shame i cant get it to work.

Another potential solution is to check your router's IP blocklist. I had the S7 Edge and now the S9+ and apparently the phone may spam the router with UDP requests making the router think you are performing a DDOS attack. Clearing the IP your phone is using from the block list may resolve the issue.

S8 on 5ghz WiFi
To get your device to run on 5ghz WiFi all you need to do is ...
Open WiFi connections ...
Add new network ...
Type out your SSID followed by a (space) and the number 2 ...
So ... if your SSID is homeWiFi ... you need to add homeWiFi 2 ... the pass key is the same and won't need changing

Your router is likely using a channel assignment that isn't available to your client devices, check the ETSI standards for acceptable use on the 5GHz band if you're in Europe.
