[Q] Question about WiFi use in Europe... - myTouch 4G Q&A, Help & Troubleshooting

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

Wifi question

I searched the forums to no avail to the following question/issue.
It states on both the Samsung and TMO websites that the networking specs for the Vibrant cover 802.11 b/g/n. My router is dual-band and throwing both g and n signals because my ipod touch can only get g. My computer is connected to the n band. My Vibrant only sees the g band but I would love to connect it to the faster n. Is anyone able to connect to 802.11n? Why would my Vibrant not see the n signal if it is capable? Whadoido? TIA.
The Vibrant's wifi is, as far as I know, 2.4 GHz only, but a typical dual band router setup does b/g only on 2.4 and n only at 5.8. If you have the option to do b/g/n on the 2.4 GHz band it should work.
How do you check the wifi connection speed?

That doesn't make the internet on the phone faster since no way you can fully utilize the bandwidth of wireless g on a phone (someone correct me if I'm wrong).Try to disable both b/g on your router to see if it takes the n.
It's for streaming and file transfer from the server, not the internet. The problem is probably band frequency. Thanks.

Does the epic have wireless N?

I've noticed that my wireless N network doesn't appear on my epic is there a setting to turn it on it was advertised as having wireless N right?

im having the same problem. it says it has n in the specs, but my network dosent show up
Are you running at 5ghz or 2.4Ghz on your home access point? Does the Epic only support 2.4Ghz N?
It does support N right out of the box. My E3000 router shows an active N connectionn when I enable the phone's WiFi.
Im connected to my wireless g network and i've noticed that it disconnects for like 2 seconds and then reconnects right away

Shows up as N on my router. Interestingly enough, max throughput for both my Epic and Evo are approximately 11 mbps.

theres probably an 802.11b device on your network. The network has to drop down to the speed of the slowest device on the network and b devices operate at 11 mbps

Force it to run on N only.
"how do I do that?"
Manual or google specific model.
It would be specific to your router. My epic is connecting to my single band 2.4ghz router. To force it, you'll need to access the router through your browser, like you would to change the network id or password.

That would seem unlikely - most modern routers support mixed-mode operation. I can push over 80 Mbit on my N-based laptop over 2.4GHz with b devices connected. On the 5GHz band, I get closer to 112 Mbit, but that's a different point entirely.
Both the Evo, Captivate, and Epic seem to top out, for me, at around 9-11Mbit. This is probably a processing limitation, WiFi chipset limitation, or chipset bandwidth limitation more than anything else.

[Q] 4g tethering

Ok so I have been searching the forums for a few days now and have yet to find the answer to my question. So please don't bash me for not using the search function cuz I did. There is a good chance that my question has already been answered and if it has please direct me to the proper thread. Otherwise my issue is that my epic is rooted as of a few days ago cuz I moved into an apartment and I don't have any Internet yet. Not for a few weeks, but I am using the android wifi tether app. That's working good for me except I am not getting any 4g speed through it. If I'm lucky i will get maybe 1 to 1.5 Mbps but most of the time less than 1 mbps. Does anyone know if the wifi App supports wimax speeds or not. Yes I have 4g coverage in my area. Where I am sitting right now on my phone speed test results are above 3.5 to 4 mbps. But while using my iPad (which I am using to write this) via wifi tether app speed tests are dreadfully low. Same with all other devices I have tried connecting like my xbox or laptop. Any help or suggestions would be greatly appreciated. Thanks in advance.
Is that the results withe 4g on? 3-4mbs? I get that with 3g untethered 4g untethered is around 8mbs. Have you tried testing it in another area? You might just be in a 4g deadspot. With wifi tether I get 3-4mbs on 4g. I can't really tell you where to go for info but those numbers sound more like 3g to me.
Sent from my SPH-D700 using XDA App
Yes that is with 4g on. Where my phone is this very second. I have 2 bars of 4g signal. And it's working fine for me. Sitting side by side with 4g activated and wifi tethering on. My phone will get 4mbps and iPad will get 1.5mbps. From the same server on speediest.net. And I run the tests at separate times so they don't conflict for bandwidth.
Update: just ran test again.
iPad - 350ms ping 1.63mbps download .86mbps upload
Phone - 122ms ping 3.96mbps download 1.2mbps upload
This is a known issue..it happens in android-wifi-tether and mobile-ap as well..its definitely using the 4g connection and wifi should be capable of transmitting more..I mean even the lowest is capable of 11mbps..but N should be a lot higher.
As far as I know there is no solution yet...the EVO had the same issue at one point but it was fixed I hear..
Maybe it has something to do with the settings on your phone. I noticed with mine that my speed would just climb and climb then suddenly just drop at around 8. It wouldn't be a slow climb either it's like it's actually being throttled somehow. Try clearing the cache or something, but for some reason those number just don't sound right to me.

In their case it had to do with a routing table..but that routing table was for HTC devices so its not related to ours...
Both Mobile-AP and Android-Wifi-Tether experience the same issue as well :/..I do not think its wifi related either..it must be something in between the software and the sending to wifi.
Reason I say this is if you try the device with 4g on 1 bar, then 4g on 2 bars, then 4g on 3 bars on both the device and on phone you will see the speeds vary..example:
1 bar
phone: 4mbps/1mbps
laptop: 0.5mbps/0.03mbs
2bars
phone: 7mpbs/1mbps
laptop: 2mbps/1mbps
If it was the wifi speed, then the speed would not have dropped so much.. something in between is effecting it
Oh.. That makes sense. It's just too bad though. Thanks for helping me understand.
Probably the way the wifi and 4g radios are set up and how they interact with each other, maybe 4g has more priority than wifi. I'm just guessing though. I don't know much

Just FYI I too was getting slow speeds but with Sprints hotspot that I was paying $30 a month for. Needless to say I cancel the feature and will seek rooting my phone and add the free tethering, casue at those speeds it isnt worth it.
Sounds like the problem you are having might be caused by something that is the result of 4G and Wifi frequencies being the similar. If you are using both frequencies in a close proximity such as a room or house the frequencies have a high likeliness of causing interferences by reflecting off each other. A way to test this would be to compare wirless tethered speeds to wired ones on the same device.... Hope this helps.

Thing is its getting full speed on the device...at the time its using wimax..so wimax is not having the issue..not to mention..there is a relation to the wimax bars and the wimax speed which is strange...

[Q]5Ghz wifi

So I've been digging into this a bit the last couple of days, and as far as I can tell the Nexus 7 doesn't support wireless N on the 5ghz range, which is sad.
I dig into this, and find others are finding the same: http://forum.xda-developers.com/showthread.php?t=1803798 http://forum.xda-developers.com/showthread.php?t=1777431
However, I have also looked into the chipset, and AnandTech.com, http://forum.xda-developers.com/showthread.php?t=1749498, and the Ifixit teardown agree that it is using a BCM4330, which supports Wireless a/b/g/n 2.4ghz and 5ghz, as well as bluetooth 4.0, and fm radio. I took a look at the radio, and the creator of SpiritFM has concluded that the chip's antenna pin isn't connected, and thus why FM isn't working.
So, my question is then; is the lack of 5ghz on the Nexus7 a hardware or software problem?
It would be nice to have the 5ghz wifi range, as my college campus actually uses it a lot.
It's a hardware issue, and I don't think the lack of 5Ghz is a problem when you consider that the wifi chip only supports single stream at a maximum 65 Mbps. There are a few other devices out there that can support up to 72 Mbps, but that's about it. Tablets and smartphones are almost always a few years behind the standards because it's incredibly expensive to manufacture wifi hardware capable of the latest and fastest standards that will fit inside of a mobile device.
Is there any evidence that its a hardware issue? The chip seems to support it, as i said.
People thought the htc dream (tmobile g1) would never run ics or jb, guess what it can! Not well, but its possible.
So why isn't 5ghz possible? No offense, but 1 person saying its not without any clear evidence wont get me to give up.
I never said speed was an issue, its mostly compatibility, cant hardly connect to campus wifi if my device doesn't support 5ghz; and the 2.4ghz bands are crowded in my apartment complex, a single 5ghz router would do wonders.

The important part to note is the "or" in the middle of that statement, which means that there are two different versions of the chip. The HTC One X, for instance, has the dual band version. We've got the cheaper single band version in the Nexus 7.

Why is my LTE device displaying as HSPA+?

Hey guys. I Have a Samsung Galaxy Note 2 (SGH-I317M) and for some reason it fluctuates between HSPA+ and 3G signals rather than LTE. The device is originally locked to Rogers but I unlocked it and am now using it with MTS. I am running on jelly bean 4. 1.2 and CleanRom 4.0.5. Anybody have any ideas as to why I'm not getting LTE?

Yes I'm getting fast speeds but I can't help but wonder why this is happening. I mentioned that I'm with MTS so I'm not sure if that's what you're looking for. I live in Canada so it's probably not familiar to you. They just started carrying S3's which are running on their LTE network and they show 4G at the top of them when activated rather than HSPA+.

It is either the towers or your phone isn't compatible with the bands of LTE (there are multiple bands like there is with UTMS).

I'm pretty sure it isn't the towers cause my friends iPhone 5 is running off LTE and he live about 5 minutes away from my house. I've also been at distances one minute away from his house and did not pick up LTE then either. I don't know much about bands or frequencies but my carrier just launched the Galaxy S3's and they run off LTE and I'm assuming the Note 2 has the same hardware. S3: 700 (Band 17), 1700/2100 (AWS) MHz , Note 2: 700(band 17) 850 AWS 1,900(band 2). I'm clueless as to what those numbers mean but i'm guessing the important thing is Band 17, right?
Try going near his house then. Or have you checked the network settings? You may have to flash something.

I have to no avail. I had a friend try to help me out over the phone with network settings and his phone appears to have a setting that mine does not. When he goes into settings > wireless and network more settings > mobile network there is an option for him to toggle between LTE, HSPA+ etc. My phone doesn't have that for some reason. All that's listed is Mobile data, data roaming, Access point names, and network operators. Nothing to toggle between networks, which is probably what I need to enable LTE. I have no idea why that setting would be absent from my device. My friend was using an S3 on the same operating system as me btw.
From what i can tell it's the frequencies . The frequencies your device have seem to be different than the frequencies the s3 have on your carrier. If it's not that then you can check your apn settings.

What model is your phone, and what model is his phone. You said you brought your phone from a competing carrier who is likely using alternate frequencies that your phone might not be picking up either due to hardware or software limitations. Without knowing the hardware, and where it came from in the first place, we can't figure out what frequencies your phone is looking for and can't answer your question effectively.
download an app that will show you what is the type of connection you are actually on.
I think that maybe its the matter of incorrect icon.
