[Q] SGT + 802.11n: Not enabled?

I just junked a netgear router with misbehaving wireless and nabbed a new one (Linksys WRT120N if you're curious) with N capability last night. I was hoping to get my SGT to connect at N speeds but unfortunately it keeps wanting to connect at G speed (54mbps). I've tried setting the router to N-only mode and the tablet still sees the AP, but it attempts to connect for a moment then goes back to scanning for APs. Yes, I've got great signal strength since I am sitting ~5 feet from the AP (the SGT icon shows full blue icon, my dbm is -34 for those of you that understand what it means).
Is the tablet's N capability disabled? I double checked the specs of my SCH-I800 on Verizon and Samsung's site and both say that the tablet has b/g/n wifi capability.
If you're nosy and want to know why in the world I'd even need N speeds, I have half a dozen computers in my house and some of them (thank you Microsoft) can't see the others for file transfers, so I copy the files over to my tablet from the source, then to the target. Not the best solution but I'd rather not toss up applications on all the computers and I haven't bothered buying equipment for a NAS device yet.
So... any revelations?

Dunno, I've got mine running on N just fine... Some of the lower end linksys routers have issues with N. You might look into dd-wrt and see if your router is compatible..

I've got a Linksys E3000 running Tomato, and my Tab connects. Notably, however, the Tab only supports some of the 5GHz channels and not others.

Pretty sure it only supports the 2.4ghz range of N. I could be wrong, but I doubt they would have included the 5ghz range of N wireless capabilities..

No, it supports 5Ghz range as well, just not all channels as I stated. My router is dual radio, and I have one SSID running at 2.4 and one SSID running at 5, and the Tab is connected to the 5 one.
It noticeably scans the 2.4 range before the 5 range, so first the 2.4 access points appear, and then the 5.

My personal experience was that I was able to achieve much much better download speeds by setting my router (WRT310N) to G mode only.
Before hand, when it was set to mixed I was getting speeds of like 1mbps download tops. Now I get 15+.

Would you mind mentioning 'some' of these channels so I don't have to manually go through all of them one by one to see if it'll work with my SGT?

[Q] Does anyone knows if it has 2.4 and 5ghz wifi?

As posted...it has the 2.4 only or the 2.4/5.0ghz wifi?

From samsungs note specifications site:
"Wi-Fi 802.11 a/b/g/n, Wi-Fi Direct"
WLAN a-band is 5ghz area, so I think it has 2.4 and 5ghz.

thanks

of course, my old galaxy s2 can connect at home whit the 5ghz wlan, so its very close that galaxy note can the same..

Hmm, anyone with a note actually able to use 5ghz wifi? I have so far been unable to.

hmm.. mine doesn't see the 5GHz radio on my Netgear WNDR3700.
Weird.
As a side note, i do think connecting to the 2.4GHz radio is a better idea as it has better range, and the Note won't be able to utilize the extra speed of the 5GHz channel anyway.

yes it works 5.0ghz also, with d-link routers.
its faster than on the 2.4 crowded band.

Mine connects to the 5 Ghz coming out of my WRT610N running dd-wrt

Works fine on my old Belkin G router (2.4Ghz) and the new Belkin N router (5.0Ghz). So yep.

The note has only antenna, so yes, it won't fully utilize it, but I get much faster speeds on the N router than the G oh and the speed drop off at the edges of reception is much less with N.

Hmm, well my 5ghz doesn't seem to be showing up. Anyone have any idea what troubleshooting steps I should take?
---------- Post added at 11:52 PM ---------- Previous post was at 11:38 PM ----------
So just an update for people. I figured out the issue. 5ghz doesn't seem to be supported on 1xx channels, but works just fine on the lower frequency xx channels. I wonder, is this an European thing? Would there be a firmware tweak to enable the higher frequency (and higher output power) 1xx channels?

+1 on that. I would like to see it able to be used with the higher channels

I think it depends on whether the router utilizes the 20MHz or the 40MHz band. I bet the note can only see the 20MHz one.

OK ppl its the channel your router has set for 5ghz. European basebands only see 5ghz channels provisioned on Europe. Check Wikipedia, specifically here: http://en.m.wikipedia.org/wiki/List_of_WLAN_channels
Simple fix... change router 5ghz channel to match region of your baseband
Using a higher or lower channel means nothing. Its finding the channel that is least crowded and has the least amount of interference.

Worked!

I wasn't able to connect with my netgear wndr4500, but this fixed it! thanks!

Or you can always flash a firmware which supports your local 5 GHZ frequency in case you have other devices which use this frequency range. I noticed that Asian firmware supports NA 5 GHZ frequencies.

I have a Linksys E4200. I tried using WiFi analyzer and put it to scan for the exact frequencies available in the E4200 5Ghz configuration, the S2 is unable to detect any 5Ghz channels. I also tried selecting all channels, but it did not work.
EDIT: Just found an answer on another thread that worked, I manually set the channel to 36. The phone immediately detected the network. Its odd that in auto the phone cant detect it.

[Q] How do you prioritize wifi access points on the N6?

Here's the problem. I have an 802.11ac router at my apartment, with two access points, one of them on the 5GHz band, the other on the 2.4GHz band.
I want my N6 to be forced to go on the 5GHz AP every time, and shun the 2.4GHz AP. This is because at my apartment complex, everyone's got a 2.4GHz router, so even though my N6 thinks it gets a stronger signal in the 2.4GHz band, it will get ****ty bandwidth from the 2.4GHz bands, because everyone in my complex is watching Netflix at the same time. The 5GHz bands are clean, so I get get far more bandwidth there.
So how do I force my Nexus 6 to use my 5GHz AP, and not my 2.4GHz AP?
Yes, I know, you can go into the settings, and tell it to use only 5GHz APs, or only 2.4GHz APs. I'm looking for the setting that says "Strongly prefer 5GHz APs, and only use 2.4GHz when absolutely desperate." That way, I don't have to remember to go into the settings so I can get wifi when I go out for coffee.
I don't want to constantly fiddle with my phone. I want an automated way to make my N6 Do It My Way.
I used to be able to prioritize access points in Kit Kat, but Google thinks we're idiots, so they omitted that feature from Lollipop.
Also, being able to prioritize access points means your phone doesn't log into your neighbor's ****ty wifi that you used once when you went over for beer, when you'd prefer it used your own wifi.
Are there any Lollipop 5.1 compatible apps that let you do this?

Can you go on your router and rename the 5ghz band to a different ssid as the 2.4ghz band.
After that only have the nexus connect to the 5ghz ssid.

That's already done, though I found that the N6 "helpfully" automatically adds the 2.4GHz SSID, since it automatically detects it's going from the same device as the 5GHz AP.

How can it connect to the 2.4 channel if you remove it?
Like I said, make it only know/trust your 5ghz channel.
Completely remove the 2.4 signal

5GHz WiFi?

Just a quick question. Specs I found say a/b/g/n but my 5GHz won't show up. I searched the forum and found some people saying that 5GHz works, others say it doesn't.

Tablet WiFi specs : WLAN Wi-Fi 802.11 a/b/g/n, dual-band
The Tablet works well with 802.11 n 2.4 GHz and 5 GHz.
5 GHz is a frequency, it all depends on your area and the Interference Level. Everyone's router setting would be different.
Select 2.4 GHz for longer range, 5Ghz for shorter range but faster communication between router and tablet.
The most important of the two is that the selected channel interference level is acceptable.

Hey thanks for your reply but that wasn't exactly my question. I'm just confused that I can't connect to my 5GHz network. I seperated them in the router settings, so it should show up in the list but it doesn't. Only 2,4GHz.

Check your router settings:
All routers works differently.
It should be 802.11 Mode n
Band selection 2.4 GHz or 5 GHz
Bandwidth (20 Mhz for 2.4 GHz) (40 NHz for 5 GHz)
Channel ( select best with intererence level of acceptable )
Make sure SSID Broadcast is enabled.

Question 5ghz wifi problem

Hi - I recently updated my OP10Pro 5G to the NE2215_11_C26 update, OOS13, US,, and my 5ghz wifi is now really slow - 40-50mbps down - unless I toggle wifi or airplane mode. Speed goes back up to normal, then goes down and stays there. Other devices in 802.11ac work just fine on the 5ghz band
Any idea what's going on?
Thanks

I had exactly the same problem and went through a "chat session" with OnePlus support about two weeks ago. I was asked to send my phone in for "repairs". The way their agent responded to my issue suggested that it is a common problem.
Edit: Sorry, my phone was running OOS 12 at the time I experienced the problem. I don't recall the build number and I don't have the phone now, so I can't check.
So, my phone has been "under repair" now for two weeks. No status update, no idea when it might be repaired or replaced. Meanwhile, I'm using my previous phone, a Moto One Ace 5G, and wondering why I bought the OnePlus at all.

I think I figured out my problem. I have Verizon FiOS, and have a G1000 Quantum Gateway AC router and the matching extender. The extender had the same SSID for the 5ghz band as the main router .. so the phone would hang on to the router or extender no matter where I moved in the house, no matter whether I checked the "switch Wifi to stronger network" box. I created a 'sub' SSID, and now the phone will (usually) switch to the stronger network, and seems to work ok.
I didn't have this with my AC Wifi OnePlus 7 Pro, or with my AX laptop. But this did seem to fix the issue with the OP10. I wonder if the new FiOS wifi 6e router + new extender would work better with my 10 Pro if extender is broadcasting same SSID?

As long as the 2.4GHz and 5GHz bands will share the same SSID that's l;ikely the phone will pick the one with the "strongest signal".
If you want to make sure to always connect to the 5GHz one, using a different SSID is the only option. Doesn't really matter which AP/router/repeater/extender you use.

Yea.. the issue was that I had the 5ghz band on the SAME SSID being broadcast by both router and extender.. forgetting the 2.4ghz didn't do anything, nor did ensuring that the "switch to stronger Wifi network" toggle was on. My OP10Pro would connect to the router's 5ghz signal when entering the house, then stay on it when moving around the house without switching to the stronger 5ghz signal with same SSID emitted by the extender. By creating TWO 5ghz SSIDs, one for router and one for extender, the OP10Pro now - usually, it isn't perfect - switches between the router/extender 5ghz SSIDs depending on the signal strength, though Android13's cutoff for defining "weak signal" seems either arbitrary or very forgiving. I'm wondering if Verizon's new Wifi 6E router + extender will fix this issue and allow me to just clone the SSID on both devices.. i read somewhere that wifi 6 and 6e devices can do this natively.. not sure as I'm a novice at best at networking. Thanks.

Other than the actual "sensibility", that's not a 10pro specific issue.
2.4 and 5 GHz bands will behave differently and the phone will "perceive" one or the other as the best choice based on various factors and the overall quality of the signal.
I had the very same issue on my laptop.

OnePlus support had my phone for 3 weeks to fix my 5G wifi speed problem. They report that they replaced the motherboard under warranty and the phone has been shipped back to me. I should have it in a couple days and will certainly test to confirm that 5G wifi speed is similar to other devices connected to my network.
I've defined separate SSIDs for 2.4g and 5g wifi in my gateway, so I can control which SSID I connect to. 2.4g was always consistent with other devices connected at 2.4g. The problem with my phone was related only to 5g.

I received my "fixed" phone about a week ago now and I've been monitoring its wifi performance. Bottom line: 5G has been generally slow, much slower than my laptop or my Moto Ace 5G, but the speed is highly variable and quite fast sometimes. I just ran Speedtest on my laptop and OnePlus. Both were connected to the same 5G SSID. The laptop performance was 304 mbps down, 172 mbps up. The OnePlus performance was 48 mbps down, 205 mbps up.
I switched both the phone and the laptop to my 2.4G SSID. Laptop performance was 43 mbps down and 15 up. Phone performance was 116 mbps down and 88 mbps up.
After the 2.4G test, I switched the phone and the laptop back to the 5G SSID and immediately retested wifi speed. I observed performance of 339 mbps down and 373 mbps up on the phone. The laptop speed was 248 mbps down and 148 mbps up.
I know that my gateway broadcasts 5G on two different channels for the same SSID and I have no control over what channels it picks. Maybe the phone picks a congested channel sometimes and the slow observed speeds are due to that, whereas the laptop (and the Moto Ace) always seem to pick the less congested channel?
The other thing I read about was "randomized MAC address" versus "device MAC address" and someone, somewhere (I don't remember where) suggested that using device MAC address resulted in improved speed. I just made that switch for the 5G SSID. Speed is very good now, and I'll monitor it to see if it slows over time.
Sorry for the long message, but I'm thinking that the "fix" really did nothing to improve 5G wifi performance and there is something not quite right about the OnePlus's handling of 5G wifi.
