[Q] Question about WiFi use in Europe...

I just moved to France and while I do have new mobile service with a local provider, something bizarre happened that I'm racking my brain trying to understand.
My Mytouch 4G works fine around town with local WiFi providers. But I'm in an apartment that has wireless service via a provider called "Free". The WiFi signal it sends out is seen by my laptop and works perfectly fine with it but the MyTouch can't see the network at all.
We couldn't figure it out. We got our new phones from here, checked for the apartment's network and there it was. So, clearly it was something about the MT4G that was preventing it from seeing the WiFi network.
Does anyone have any clue how this could happen? Doesn't seem to make any sense to me. If it was a regional thing then why does my laptop see it no problem? But with the MT4G and incidentally the Galaxy Tab I also have, neither can see this apartment's WiFi? I just want to understand this because I'm so curious what causes this!
Thanks!

WiFi 802.11n network, perhaps? And MT4G ROM that doesn't support it?

All mytouch roms support N, most support dual band. What's even more interesting is that the galaxy tab wasn't picking it up either. Could a laptop connect to it?

While I would agree the stock ROMs for the MyTouch have support for the 2.4 and 5 GHz bands for Wireless N, I have found only a couple MyTouch ROMs support the 5 GHz bands. In fact, when I would use a different kernel with a rooted stock ROM, I would lose the 5 GHz band. It could be the issue is with the 5 GHz band. If the WiFi network is transmitting in the 5 GHz band and the laptop WiFi card supports both bands, but the ROM does not support the 5 GHz band. If memory serves, Faux123 kernels support 5 GHz wireless N band
If you would like to test my theory and remain rooted, perform a backup then flash this ROM at the link provided.

This is so unbelievably bizarre. It's tested every ounce of knowledge I have about wifi.
- The tablet and phone ROMs don't even see the network in this apartment. Both can handle b/g/n connections.
- The laptop sees the network here and connects fine. Perfectly smooth Wireless-N
- When we're out both the tablet AND phones can connect to public, restaurant, and cafe WiFi
- We get our new local phones, turn on WiFi, immediately the apartment's network shows up on the top of the list
Of course, we already have local phones but I now HAVE to solve this mystery because I will probably learn something at the end of it. So, I'm on a mission now. :laugh:
I hope it's ok for me to post this...
Here's the tablet's ROM: http://rootzwiki.com/topic/11697-rom-cdma-aosp-ics-cm9-build101-0418/
Here's the phone ROMs:
ARHD 7.0.4 - http://forum.xda-developers.com/showthread.php?t=1504718
Virtuous Unity 1.29 - http://forum.xda-developers.com/showthread.php?t=1143177&highlight=virtuous
I don't see anything that could cause this problem in any of them. Any thoughts?

Both Galaxy Tab and MT4G have problems recognizing 5GHz 802.11n. Just google.
Not all kernels work, not all ROMs work. On MT4G specifically, as 4Orr correctly stated, very few kernels do.
99.9% that it's your problem. Do what 4Orr suggested and test it. It takes exactly 15 min to do it.

Cool, thanks

[Q] N900?

I need to buy a new WiFi router. Would the N10 be able to take advantage of an N900 router over an N600 or N750?

Hi,
Got a 900 router, ASUS RT-N66U, nice router BTW.
I did test the tablet in all variations.
On 2.4 GHz it runs 2x2 single channel (20 MHz), 130 Mbits max link rate.
On 5GHz it runs 2x2 dual channel (40 Mhz), 300 Mbits Max link rate.
If you only use the router for the tablet 900 is overkill.
Having that said. I would definitly go for 600 at least.
Avoiding the crowded 2.4 Ghz is worth while.
I looked at smallnetbuilder and checked out routers.
Settled for the RT-N66U because it has excllent firmware support (look for RMerlin) as well as excellent reach on the 5 Ghz band.
Good luck.

Yeah, I've heard nothing but great praise for that Asus. I don't really need a router right now, but am considering getting one because of what I've heard. I think Morfic (Trinity Kernel) researched them all at one point & settled on that one.

Based on the reviews here and elsewhere I went ahead and ordered the rt-n66u today. With some luck it should be here before the weekend.

Have a look at http://forums.smallnetbuilder.com/forumdisplay.php?f=37
Check out the Merlin subforum, best firmware, stock with bugs ironed out and a few extras.
If you dont have many walls or distance to cross us the N10 on the 5GHz band. rocks. Otherwise make sure you force the 2.4 GHz to single channel (20Mhz) otherwise the N10 seems to get confused.

I usually use dd-wrt. I actually verified compatibility before ordering. I might try this other firmware, but what is the advantage of merlin? I've never heard of it jefore.

Its specific for a few Asus routers, excellent wireless performance and close to original Which is tomatoe based . Have read the through the thread other. Suggest we keep there as it really no longer relevant to the N10.

802.11ac highly underrated with Galaxy S4 launch?

I personally think that this is a major milestone for any mobile phone yet, no one seems to be talking about it. Why is that?
Isn't this sort of stuff supposed to make waves in getting 802.11ac into mainstream use? These are the type of headlines that should be discussed to death and made a big deal out of yet it just had a little mention in the launch and not a lot of new stories about what draft it was and which routers today would be best suited etc etc.
Discuss please?

Ok agreed, this is a monster on paper, but it will be suitably replaced next year with a 16 core device maybe. or better yet, some sort of cloud service driven by LTE network speeds with hundreds of supercomputers working in tandem, only to fall back on local CPU power if the cloud is not available or loss of signal (I love speculating).
BUT !!! and its a big BUT!, 802.11ac will be here for a good few years, way past the Galaxy S4's shelf life.
This phone will drive the prices down for ac wifi routers and hotspots, however I dont think that this is the final version of 802.11ac which is why they are all hush hush about it?

Launching
I can't wait till April. The launching of the new Samsung Galaxy S4 is one of my most awaited event. This phone is taking us to the next level folks!

I think most of us doesn't have an AC router yet. But it's definitely futureproof with AC. My PS3 still uses Wireless G for god's sake.

Are you saying that there will be no 16 core CPU's in the future? Its like Bill Gates saying back in the 80s that no one will ever need more than 8kb of RAM. If you are referring to the S4, yes, I know 4 cores for processing and the other 4 for battery saving lighter tasks. This however has not stopped Samsung marketing the device as an 8 core beast.

Does anyone know which draft of 802.11ac the S4 has? IEEE have not yet finalized the standard yet. Is there a possibility that this ac chip that Samsung have sourced for the S4 may become redundant if IEEE change the AC specs?

Only because they are bloody expensive to buy. What if the S4 can turn this around and make these affordable for all? With the launch of this device, maybe, just maybe, the following happens
1. Demand intensifies
2. Competition want to offer the same functionality and hardware (APPLE, HTC, NOKIA, HEAIWEEEEEEEEEE, LG)
3. Hype and buzz intensifies
4. News stories pop up all over the place faster than ever about the AC spec and how amazingly super fast it is
5. A lot of manufacturers trialing and testing AC routers and hardware
6. Prices become affordable as volume units start making their way worldwide
7. Price come down futher by retailers trying to outsell each other with deals / discounts / coupons / promotions
8. Eventually ISP's start giving these out for free to their ADSL and fibre customers
9. People begin to reap the benefits of up to 1.7GB speeds over wifi
10. The whole world forgets about 802.11n like it never existed

Please stick to the topic now?

Wonder why this thread has made its way to the Q&A troubleshooting area?

To be honest 802.11ac in the first wave is going to be kind of pointless. In reality it is basically just 802.11n with wider channels. 802.11b ---> 802.11g are big changes. 802.11g ---> 802.11n are big changes. 802.11n ---> 802.11ac, not so much.
It doesn't say buy I am guessing it is going to be a 1x1:1 like the SIII. I would rather have a 2x2:2 802.11n that a 1x1 802.11ac
Here is how it works out.
SIII - 802.11n 1x1:1 at 40mhz = 150mbps
Nexus 10 - 802.11n 2x2:2 at 40mhz = 300mbps
S4 - 802.11n 1x1:1 at 80mhz=325mbps
the Nexus 10 has two antennas and radios compared to the SIII or S4. It should be able to hear and transmit better.
WiFi has a **** load of overhead so you normally get about half of your connection rate in real throughput. With that said I only get about 90mbps with iPerf when my Nexus 10 is connected at 300mbps. It is like the bus on the thing can't hang. Copying files from a server with ES file explorer is super slow.
I haven't played with an s4 but the bottleneck on the other devices isn't the wifi.

AC router
I currently own an AC router... Since I live in the UK and Broadband Speeds are just well totally b**l s**t, there's not really much of a point of ac on that basis N is more than capable of reaching speed of up to 300 mbps
Till broadband speeds dont catch up with the N there's not much really any point of ac
only time i think ac will actually benefit a user is particular when media streaming or wifi file-sharing and that also having the actual host connected via Ethernet or ac.

So what? The majority of internet service providers in most countries don't even provide enough bandwidth to saturate 802.11g.
802.11n and 11ac are good for transferring huge files from a desktop to a laptop, but really, not of much use on a phone. g alone is sufficient to stream a 1080p H.264 stream.

I'm located in the USA and currently using a Netgear R6300 AC Dual-Band Router and can only get the S4 to connect at 802.11G @ 54Mbps. I see no options to change the band speeds to 2.4Ghz/5Ghz which 802.11AC runs on the 5Ghz band. Very disappointed on Wifi and feel Samsung made false advertising... I realize AC is technically [draft] but the S4 should atleast connect using 802.11N.

Nexus Play does not like 5ghz N network..disconects

I posted about having trouble the first time getting it connected to my 5Ghz network but i got that to work finally.
Now the issue is it will say it is connected and it will work fine....until i leave it for the night. when i come back to it the player will say im connected to the network but there is no internet. have to disconnect and reconnect for it to work. Going to try it on my 2.4ghz network tonight.
They need to get to squashing these bugs!!!

mine has been running on my 5ghz n network since I opened it up a few hours ago no issue....then again it is like 3 inches from the router. If your router is a good distance from the device 2.4ghz would be better as it generally has a longer reach than 5ghz or at least that is my findings as anything in my bedroom has a hard time connecting to my 5ghz as apposed to the 2.4

Well my router is right next to my Nexus player... Maybe it's the router that is the issue. Have to check more into it. Been meaning to upgrade to an ac router anyway

You and me both especially since I have at least 3 devices that support AC.

if you are a fan of linksys/belkin, the wrt1900 is a tough router.
i currently use a ea9200 (ac3200) which is a tri band router. 2 5ghz bands and one 2.4. i would seriously consider moving up to ac1900 based routers...

Wifi issues?

Hi!
My S4 simply won't connect to my 5GHZ AC Wifi (but succeeds on the 2,4), unlike my Nexus 5 which connects to both.
Thanks =)

Which 5GHZ band are you using on your router? The 20 MHz or 40 MHz band ? Be more specific.

I would have been more specific, but I did not even those bands existed in the first place.
So I have no idea, sorry!

20MHz or 40MHz are settings on your wireless router.
To answer this question you need to check your router settings.

Try this
You may have a faulty S4 like mine. My phone would say it has a good signal to both the 5GHZ and 2.4GHZ but would only connect to the 2.4GHZ signal. I could connect to the 5GHz signal only if I stood beside the router. When I borrowed someone else's S4 and stood a reasonable distance away, it would connect to the 5GHZ signal no problem, whereas my phone wouldn't (standing in the same place).
Try connecting to someone else's 5GHZ router or using a different S4 to test and compare. If its the phone, I would get a replacement phone or send it in for repairs, if it's still in warranty and not rooted or modded.
Also remember that 5GHz has a shorter range than 2.4GHZ and that the Nexus may have a better antennae than the S4.

I'll definitely give it a try, thanks a bunch!
