Where is wifi N?????

Videos for the htc desire show it with wifi N and the spec sheets show wifi N. Does anybody know if any G2 tear downs show that it does infact have the hardware to run N? Are the devs working on enabling this?

Yes it does. I have wifi n at home connects just fine.

I have tried wifi n at two differ locations.. my gf doesn't pick it either and neither does my friend's g2. What we doing wrong? Our laptops pick up the band easily.

Wifi N can run on either 2.4 GHz or 5 GHz. The G2 only supports 2.4 GHz, but many people run their N routers on 5 GHz to avoid the congestion on 2.4GHz.

You need to go to Menu-Settings-Wireless & Networks -Than Wi-Fi Settings to connect to nearby networks. I noticed when I turned on the wi-fi at first it did not connect right away. You need to view the wireless networks in order to connect. Once you connect it automatically saves. So each time you turn on your wi-fi it connects automatically.

It took me forever to figure this out with my N1. I went through all of the trouble of reconfiguring my router to use N on 2.4GHz, and it didn't make much of a difference anyway. Went back to 2.4GHz for b/g and 5GHz for N (my router has 2 radios).
I actually get a faster/better connection over HSPA+ (up and down) than I get through my router and cable modem.

Most dual band routers running both b/g and n will only allow n to run on the 5ghz band. You can only switch frequencies if your router is running the n band alone.

[Q] Widget to toggle 5ghz/2.4ghz

Hiya folks I am hunting a widget to toggle between 5ghz and 2.4ghz, I am running a Carbon Rom and my router supports dual although my lovely Nexus will only connect to my 2.4 network if on auto, I have to use advance settings in wifi and select 5ghz only, so I would like to turn on 5ghz whilst at home at a flick off a switch!
cheers all43

I have a dual band router, and it has 2 separate SSID's - one for 2.4 GHz and one for 5 GHz. Can you just "forget" the 2.4 GHz network on your phone, or do you only see one network?

My 2.4 has better range (of course not speed) and all my 'other' wifi spots out and about are 2.4 only, also when in auto network my Nexus only sees 2.4ghz.
Edit
Bad manners...forgot to say thank you for your reply.

Wifi problem - what router do you use and what is the configuration?

Some people have no problem, while others like myself have issue. So let's figure out if this is a router config issue, since most Wifi problem with Android have to do with the router itself. I'll start off with mine.
Tablet date of purchase: September 12th
Router: ASUS RT-N66U dual-band (2.4 & 5 Ghz) with latest firmware
Wireless configuration:
- 2.4 Ghz for B/G
- 5 Ghz for N only
Distance from router to tablet: less than 50 ft
Issue: sporadic network connection. I got full Wi-fi signal bars, good Internet connection, but then cut-out and no connection. Back again after 10-20 seconds.
Fix(?): Changed the router configuration for the 5Ghz radio from 20/40 Mhz to 40 Mhz. This seems to tame the problem. I still have sporadic connection, but far less and connection is back again after a few seconds.

I have a TP link single band N router configured for b/g/n. Both my shield portable and shield tablet have issues with wifi. My nexus 7 and my moto g are perfectly fine on it.
I think in my case I've narrowed it down to the router, though. I have a second router upstairs, also tp link single band N (different model). It is configured in bridge mode for the main router. Both shield devices are perfectly fine when connected to it. Unfortunately it only serves a small portion of my house and is much slower over all.

A robust wifi area will hide most any weak wifi. Catch is most areas are not robust.

What do you mean by robust? Not crowded?

Strong signal with minimal set up conflicts.

I'm using a similar setup, but an ASUS RT-AC66U instead of the N66. A frequencies are mixed-mode, and my 5GHz is 20/40Mhz. I can pull a consistent 20 Mbps down usually, without any issues. 50 Mbps down if I'm the only active network user at the time.
Wifi signal is usually at 2 bars, but I'm getting the same signal level out of the Shield Portable, my Nexus 5, and Nexus 7 on my 5Ghz net. My 2.4Ghz net is usually always full strength.

That's interesting. I wonder if my N66U is unable to maintain a stable and consistent 5Ghz connection. So you have no problem with the connection like mien?
Do you use DD-WRT or stock ASUS firmware (what version?). I may end up buying the AC66U just to test it out.

Using a virgin hub which is a netgear i belive, 2.4 is solid even two stories away from the router. 5g is still there 2 stories up but will drop out, only 1 story up it's 1-2 bars but never drops out. 5g band on router set to 38-40ish range.

Don't you need 5Ghz to play GRID? If I use 2.4Ghz, GRID will "complain" and won't start any game I selected.

I have the AC66U as well and have no problems at home but have severe wifi difficulties at work or when hotspotting to my mifi which is annoying.

Stock. Whatever the latest version of firmware is too- I update when it's available.

When I had problems with my Luxor tv connecting changing channel on router from auto to one of the numbered ones fixed it, perhaps it has the bug where your device ends up getting the same IP as the router. Worth a go!

Advanced Wifi - Auto vs 5 ghz vs 2.4 ghz

My download speeds at home on the 5 ghz band setting are around 225-235 mbps, which is the same as my laptop. On the 2.4 ghz band setting my speeds are 85-95 mbps. With my phone set to Auto it always selects 2.4. Can this be fixed? Should I set the phone to always run at 5 ghz? Or should I just forget about it and leave it on auto?

My modem have 2 different wifi
1- Yavuz
2- Yavuz_5G
I'm connect 5Ghz wifi channel always on my device
You must connect 5Ghz channel

The question was for general purposes, like getting the best speeds when I'm out and about, not just for when I'm at home. Sorry I wasn't clear on that.

Samsung Galaxy A20 5ghz Wifi not working.

To be clear off the bad, its not the router. Every other device in the house that connects to the 5ghz band works flawlessly. This is a brand new international phone being use with AT&T in the US, calls and texts function fine. Phone is fully updated and so is the router.
Wifi however is only picks up 2.4ghz bands. Not 5ghz.
Wifi analyzers pick up 2.4ghz but when switching to 5ghz I get a messages stating my phone does not support 5ghz. Anyone else with this issue?

@aq3e No. It doesn't have 5GHz.
2.4GHz has better penetration through walls anyway.
5GHz is really only good if you're in the same room.

The A20 does support dual band, but it's disabled. I tried to enable it by replacing the mx140_wlan.hcf file located at /vendor/etc/wifi/ with the one from the A30 and it worked, but there's a problem.
For some reason the signal range is terrible, to detect a 5 GHz network the phone needs to be next to the router, if it gets some centimeters away the signal drops at the point where the network is not detected anymore.

5ghz wifi is certainly not only good in the same room, check online heatmaps of 2.4 vs 5ghz to compare, it's not a huge difference. Given how much less interference you will get on the 5ghz it often works a lot better than 2.4ghz even at longer ranges. Fix peoples internet for a living and I've seen thousands of peoples speeds double or even triple from changing to 5ghz even when router is on the first floor and they use it on the second.

It shows that 5ghz suffers from greater attenuation rates than 2.4

(I know this doesn't help much with the OP's question but to dispel hearsay I felt it needed to be said.)
I know you don't know me, but I said I resolve peoples internet problems for a living both on supplier and consumer side and have tested this with thousands of customers but you trust a random article with very little info more and don't even bother to look at heat maps? This article has been made by someone who read a blurb about wifi, but they did get one thing right...
"A lot of electronic devices and appliances use the 2.4 GHz frequency, including microwaves, baby monitors, and garage door openers. If you have many of these in your home, or if you live in apartments or condos surrounded by other people, that 2.4 GHz band is likely to be congested, which can damage speed and signal quality."
That list is very short, it also includes lots of computer peripherals, security cameras, smart home devices, walkie talkies, radios, remote controls, wireless handsets (landlines, not mobiles) basically every wireless device you can think of uses 2.4ghz and even your microwave! all these devices on a long range signal means your neighbours devices also overlap to combine together to make the 2.4ghz band for most consumers a disaster for anything requiring more than slow speeds. This goes without even mentioning that the 2.4 ghz band only has 13 channels (3 none overlapping) to spread every wifi device out on to stop interference, in most residential are this is simply not enough. In many cases this is so bad that even next to the router people can lose 80 - 90% of their speeds or have so much interference that even loading webpages takes a long time due to the amount of data being lost.
Like I said before, even if the 5ghz DOES have shorter range, it is not so short that you have to be in the same room, what would be the point? That is a something people assume because it's a "shorter range signal" but it's not that short! the 5ghz is usually faster due to it's naturally higher data rates and more consistent due to the lack of interference from intermittent signals. Most things that interfere with 5ghz are constant and therefore it's much easier to test and know what speed you can get in other rooms away from the router, unlike the 2.4 which has the same issues with passing through anything only with a load of other issues on top too!. The 5ghz also has the advantage of having over 100 wifi channels to spread networks out on to avoid them interfering with each other, a vast upgrade to the 2.4ghz.
Here is an example of a heatmap comparing 2.4 and 5ghz but just looking at any article that goes beyond a very brief description will show you why the 2.4ghz is often so much worse than the 5ghz.
What's the Difference Between 2.4 and 5 GHz WiFi?
What do these numbers actually mean? Does it realy matter? Is one better than the other? How many questions are we going to ask in this description?
socialwifi.com
2ldr - It depends on your house and nearby networks, test both bands with different devices in different rooms and compare speeds, outside of doing more thorough testing with other apps and equipment this is the easiest and quickest way to see which will work better.

You have 2 choises use BT modem BT modem Plan A: one Device in 5GHz network one device sharing Internet from BT modem feature. +Advance use Open Garden mesh client for better Internet throught BT modem. Construction of my plan:One or two devices in 5GHz WiFi network and 3 devices creating PAN network trought Bluetooth.if Your Bluetooth version is 5.0 you can use Mesh network profile. than using Mesh network structure. Mesh Bluetooth network structure helping one device to other. but you need to know you will use 2.4GHz trought BT modem and Mesh networks.

I fixed this issue on crDroidAndroid-13.0-20221126-a20-v9.0 by copying both mx140_wlan.hcf and mx140.bin taken from this a30 git. Works great on my a20.

No luck. I still have the signal issue

Do it again in the following order maybe ?
1. Download both mx140_wlan.hcf and mx140.bin from the git I gave you above.
2. Turn your wifi off.
3. Reach /vendor/etc/wifi folder using your favorite file browser ( Mine is Mixplorer ).
4. Overwrite both files.
5. Reboot your device.
6. Turn Wifi back on.
7. Do a Wifi speed test ( Wi-Fi Sweetspots app for me ).

I use a Magisk Module instead of directly overwriting the files, but this should make no difference. I believe it may be a hardware difference between our devices. On the schematics the 5GHz antenna seems to be marked as optional, maybe that has something to do.
I tried to put my device next to the router, and when I did it the network got detected (with bad signal tough), I could connect and the download speed oscillated between ~50-200 mbps (my network has 300 mbps). Once I moved further from it, the WiFi disconnected as the signal was lost.
