just a basic question on wifi, is it possible that not all AP can be detected?

Hi, i thought this falls under hacking so I posted it here. First off, allow me to mention that my device is an O2 Atom. I work for a corporation w/c has it own internal security implementation. I'm not sure, if the said corporate security is the reason, that I could not detect any access points(AP)? But my pc w/c also has a custom corporate build, can detect and successfully connect to the APs. Can the corporate restrict or hide it from an unauthrorize personal device, like my O2 Atom?
The wifi in my atom is working fine, as I could verify this by connection from my brothers house, w/c has his on personal internet connection w/ wireless access point(AP) setup. I've also used several wireless detection applications here and there, but still could not detect wifi in the office area. Kindly advice.

The Atom (as far as I'm aware) only supports Wi-Fi 802.11b
One reason is the network you cant see might be a 802.11g or n, which is not able to be connected to.. you can nicely ask your network admin to enable .11b backwards compatability.
Another reason is because they are maybe not broadcasting the network name SSID, your device cant see it - even though it is actually there. I don't know if the Atom has the ability to specify a network connection it cant see.
Hope this helps.

can a registry tweak enable this 802.11g or n thing? i saw in one of the threads here the said registry tweak and sk tools has this. i tried both but still no luck would you happen to know if it is hardware or is it really possible to strech this capability on atom?

the g/n wifi options are hardware specific, so unless you want to buy a new phone you might be out of luck, sorry to say.
I'm surprised your network admin has not enabled 'b' compatabilty, but there's so many different security concerns he may have done it for the right reasons. Talk to them, it's the only way to be sure (be warned though - a lot of admins wont like you using non-offical hardware on their networks)

hi snachez, our network admin verified that our APs are running on B and G. i've also verified that my unit is B compliant. btw, my device is an O2 Atom. i think i mess it up with the registry tweak i mentioned before. apparently is it for another device. my mistake this is the said registry tweaks:
HKEY_LOCAL_MACHINE\COMM\TNETWLN1\PARMS: dot11SupportedRateMask=1
HKEY_LOCAL_MACHINE\COMM\TNETWLN1\PARMS: dot11SupportedRateMaskG=8

Your problem is probably that the SSID isn't being broadcasted, so you'll have to connect manually.

btw, i'm using a cooked rom. maybe there is somebody out there that is still using the official wm5 for o2 atom, please verify and post the default(O2 Atom official wm5) registry of HKEY_LOCAL_MACHINE\COMM\TNETWLN1\PARMS: Thanks in advance...

WiFi Connection Not working

I have today taken the plunge and downloaded Android for the HD Mini. First of all, thanks to anyone and everyone involved, it is wonderful to have Android on the HD Mini.
I initially had problems getting the HD Mini to connect to my WiFi router, even after following the advice of setting the IP address manually.
I was double checking my IP settings when I noticed that the MAC address of the 'Android' HD Mini is different to that of the 'WM6' HD Mini. As I have MAC address filtering enabled on my router, the connection was being rejected by the router as having a non acceptable MAC address. Adding the MAC address of the 'Android' HD Mini into the MAC filters of my router was all that was required.
Thought that this information might just help anyone else having WiFi connection problems.

this is a known issue see here http://code.google.com/p/photon-android/issues/detail?id=19
p.s. you shouldn't open a new thread...!

Thanks for pointing that out. Unfortunately, I followed the instructions here:

This in turn led me to here:

19 Defect Accepted Low ---- [email protected] Wifi fake MAC addr
***
And then I went here:
***
What steps will reproduce the problem?
1. launch adb, type ifconfig eth0
What is the expected output? What do you see instead?
Wifi MAC address is static (11:22:33:44:55), it should be unique to each phone. This might cause issues when connecting to Wifi network.
Hint: need to make it dynamic in wifi NVS driver
***
Sadly I was too stupid to make the link between my problem (unable to connect to a WiFi router) and the problem detailed of 'Launch adb, type ifconfig eth0'.
The MAC address indicated is also missing the leading octet of '00:' (making the correct MAC address 00:11:22:33:44:55) which could easily confuse another simple soul like myself.
I spent well over 2hrs messing about with this and getting very frustrated. I thought I'd take the time to help others and save them the same aggravation. I do think my description better fitted my particular problem, and that I presented the solution in a clear and concise manner, to allow anyone suffering similar problems to not only locate the problem, but a suggested solution too. As there seemed not to be a thread with this problem/solution, I did indeed start a new one, I apologise if trying to help is not acceptable behaviour.

The point of my post was that while you might be aware of this problem, it wasn't found by a search of this forum. It was only located after following three external links. Once at that final link, was there any mention of needing to alter settings on a WiFi router with MAC address filtering switched on?
I don't feel this was obvious in any way and therefore still do not believe my post was futile.
Perhaps My post title could have been: 'WiFi Connection Not Working Correctly on Routers With MAC Address Filtering Due To The Android MAC Address Differing Between Android And WM6' ? But that didn't fit on the page.
People constantly criticise members for 'useless posts' and not using the search, I merely thought if I entered a post detailing the problems relating to MAC address filtering it would save other people from asking the same question again.
I wasted my time, please remove my posts and this thread.

relax, please understand that we have been discussing many times about wifi connection issues since almost begining of the year, so you can understand people may slightly lose their patience when they see this topic started by a newcomer on the forum
like you said, this case will be helpful for those who filters MAC on their routers.
if you have ideas to help porting, test or report issues feel free to post, just be sure it has not been discussed already
of course you are most welcome in the "mini" community of hd mini

[Q] Able to connect to many different WiFi Networks except school ones

Hello all.
I can connect my Nexus 10 to my home wifi (password protected), my girlfriend's home wifi (password protected), and the wifi at public places (I've only tried ones without passwords so far). My only problem is when using my University's Wifi. They have one that you use with an account and password, and one that is free (though you need to sign in using an email via a website. Kinda like hotels).
This is surprising to me because I have a Galaxy Nexus running the same OS (4.2.1) and it can connect just fine. When my N10 tries to connect, it says "connecting" for a second or two, and then it just says "Saved" but never "connected" and it never shows a wifi connected symbol at the top right.
I have read multiple posts about wifi problems from 4.2 but couldn't find any specifically buggy wifi problems like this. Have any of you heard of this or a solution to it? Any help would be appreciated!

Have you tried a reboot? Also check to see if your frequency band is set to auto under advanced wifi settings.
Gotta love university security and logins... they can't leave stuff simple

Oh yes. I have rebooted many times and tried using auto, as well as both frequency bands separately.

Hmmm...are you on stock?

Yes I am. Stock on both my Gnex and N10.

I wonder if using a third party wireless manager would help. Search the PlayStore and try one or two. Before you do that, go into your normal WiFi settings and click "forget this network" on the university one.

Hi there,
I work at a University in the midlands and had the same/similar problem. It's to do with certificate revocation in Jellybean (and also the latest ios my colleague tells me). For example on my Nexus 10 I was able to see the network and obtain an ip address but the webpage where you login wouldn't redirect or load. I don't know what Uni you go to but we are advising people to give the IT dept a call and give them your mac address and they can create a fixed profile.
Hope this helps

I'll definitely try the third party app. As for telling the n10 to forget the WiFi, I tried that many times too
Well that's why I mentioned my gnexus because they're the same android versions so if it works on one it should on the N10. I actually work for tech support at my university and my boss couldn't figure it out or suggest a process like you described. Thanks, though!

Oh yeah you did mention your Galaxy Nexus, my bad! let us know how you get on with the third party app. You could try giving your N10 a static or reserved IP if you have access, as a workaround!

Hey guys,
I'm from France and had such trouble with my Motorola Milestone and my HTC HD2 (and friends too with Samsung Galaxy S2 and Sony Ericsson Xperia Active) with my school's network. If it's an Eduroam network, try Eduroam Fixer from PlayStore, it helped all of us except one Samsung Galaxy S2. Give it a try
https://play.google.com/store/apps/details?id=nl.luqq.eduroamfixer&hl=fr

I wish I could use that app, but it says I can't use it in my country (USA)

Make sure you have the EAP set correctly and check if you need a phase 2 authentication. For example, here at UofM we use PEAP for eap and mchapv2 for the phase 2. If you don't have details like these, your tablet won't connect even if you have the proper login.
You will find them at the top of the page you use to login to a secure network.
Hope this helps!

Yes, that is exactly how the secure WiFi is set up at my University, too! What should I do in this case?

Edit: Nvm, Just noticed this was already tried
I had a similar issue with my One XL. It was a frequency issue. I switched it from 5ghz to auto and all was good.

Okay so I found out that my N10 is able to connect to the exact same WiFi network when in another building. I believe there is just an issue connecting to the specific router used at a computer lab. Will update when/if a resolution arises for that lab.

Nexus 4 Wifi Issues - connects to router but no internet

Just want to know who else on XDA has a similar problem to me on the Nexus 4.
Recently moved country and took my Nexus 4 with me, got a data plan, no problems there. I was also was given the stock router for my ISP (Movistar) when taking out my broadband contract and my Nexus 4 is the only device that won't connect to wifi.
So here's what happens:
1) Network can be seen on the Android 4.2.2 Wifi Settings
2) I can connect, either by WPS or by entering the password, and Nexus 4 shows connected with indicator
3) Indicator instead of being the standard blue is grey, which seems to be no internet connection. I can get some access but at very, very slow speeds (about 9kbps)
The Nexus 4 is the only device in my house with the issue, no problems on PCs, iPads, etc.
Google have acknowledged this is a bug and there is a fix which involves root, but I don't want to root at the moment. Google also say it'll be fixed in the next update, but they've said that and we've seen 4.2.1 and 4.2.2 come out in the meantime.
Google Support also sent me a rubbish response to my questions about when it'll be fixed, telling me what Wifi is and how to turn it on and off..
So just want to know, are you having the similar issues with certain routers on 4.2.2 (stock)? I know I'm not the only one but I couldn't find any other threads.
Thanks!

I started having this same issue man! care to show me whats the root needing fix?

There are a lot of fixes in the Android Development Section.

Typically this can be a DNS problem if your router is not correctly set up to relay DNS requests (windows/OSX tends to be a lil smarter about it if it can't get the appropriate response from the router).
You could try to set a DNS yourself such as google's public ( 8.8.4.4 and 8.8.8.8 ) in the advanced properties when you long press the SSID you're connected to and see if that allows for internet access. If it does, then maybe you just need to log into your router and correct the DNS info.

Thanks for the responses guys

Tried that I'm afraid :/ No luck. According to Google it is the fact "they have no drivers for that router" considering they will probably have a generic driver for the average user to connect whatever the router.
Sadly I've had to practically try everything to get it to work. Thanks so much for your response though!

Hi! It's an annoying issue, I'm currently tethering through Mac to get it to work. The root fix does work but drains battery life a lot more (instead of 0.5% per hour drain it's 5%). If you want to look I'll pass the link, but wouldn't recommend it.
Thanks!

See if you're able to do a traceroute from within android when connect to the router to see where it's failing.

Mine got fixed by changing the routers channel, weird cos' no other thing connected had a problem, not even my sister's nexus 4

Hi, tried this and have no problems. The only issue is it takes too long to complete, which is the 9kbps download issue I was having. I'll attach a screenshot of the traceroute if needed. Thanks for the reply, much appreciated!
And about changing routers, not possible at the moment. I've just moved abroad and have my old router somewhere too hard to find. Google are no help with this which is the problem, but if it persists in the next update I'll get a new router whatever the case.
It's strange since my iPad and all my other devices work with no problems!
Good luck, hope yours works now!

Just to get an idea, what router models are you using? I'm on Movistar's stock router - ASL-2665 - common issue with this router. I've also heard big brand routers having similar problems, anyone got any problems with a particular router?

The Nexus is a great phone, just a few odd issues which hopefully will be fixed.
This issue is persistent but dependant on the router. For example, my extender works perfectly whilst the main router doesn't - let me know what your router model is and I'll check to see if this will be common for your router

Hi!
Taken a quick look and doesn't seem to be any problems with your router. What you can do is to purchase the device and test to see it works on WiFi.
If it works, you're good to go!
If not, try some troubleshooting, so change channels, IP address, or even just a reset of the router could work.
Still not working? You can try what I did and buy an extender, but that'll set you back a bit of money.
You could wait until this is fixed, which we don't know when yet, or if you can't fix it you have a return period on which you should get a refund from Google.
Let me know what you decide to do, personally I'd try it out since it's likely to work, but I would return if not. But the Nexus 4 is a great overall device for the price.
Hope this helps!

OP, have you checked to see if this is an issue with the wifi access point of your router, or actually a routing issue?
To do this, set up ftp services on your computer or phone and login from the other device and copy a file from one to the other. If the bandwidth is good, your problem isn't with wifi but rather a routing issue that can likely be addressed in its settings.

I'm about certain this is to do with the router itself and not a routing issue, this is a common nexus4-my router problem and various other models.
I've adjusted every setting possible in the router settings to no avail, and all of my other devices which include other android devices work perfectly.
Sadly it seems to lie with a Qualcomm driver from what I've seen, and hopefully Google can fix in the next update

If you don't bother to check if you have good throughput over your LAN, you'll never know whether this is a wifi issue or a routing issue.
Drivers talk to hardware, i.e. Your wifi chip. That is all local, and has nothing to do with the routing (Internet) part of your router. Without knowing where the actual issue lies, you're just guessing if a new wifi driver will help.

Sorry, you seem to have misunderstood me and you're obviously making the assumption that I haven't already checked for routing issues.
As I said, my Nexus 4 is the only device in my house with this problem, all others work perfectly. From what I've gathered from these issues, it lies within the drivers of the phone.
WiFi works perfectly on every other router I've used with my N4, it's only my home router with the problem. It's a Movistar default router and other users have the same problems with this router (the brand is fairly unknown).
And I'm definitely not guessing that it's a driver issue - I've had this problem for over a month, I've tried everything I can: changing router settings, resetting, etc. So I doubt this is a routing issue but more an issue with the device, and from what I've read on other forums, this could be down to a Qualcomm driver issue.
Thanks for your help anyway!

I am not assuming anything. Simple troubleshooting 101. You're not getting a decent Internet connection. Could be wifi or router. I merely offered a simple method for determining which one.
Don't know who you spoke with at Google, but first couple of support levels don't have the stones to try and solve these things. And while I have no doubt other folks with the same setup are also experiencing this issue and that Google has recorded this info, that doesn't mean that a workaround is impossible.

[Q] Bizarre DNS Server issue post-root

Hi all,
I've tried to resolve this using pre-existing threads, but it seems that this may be a very specific issue that hasn't really arisen too much.
I am in the process of creating my own website and wanted to check what it looked like on different platforms; it loads fine on Windows, Mac OSX, iPhone and iPad. It'll also load up on my Galaxy S4 when connected via wi-fi.
I tried to show a friend while I was out and connected to 3G mobile data...and both Google Chrome and the inbuilt browser are returning DNS errors. This is the ONLY website that it is happening with.
I've checked the backend processing and due to it working on other platforms I've ruled that out as being an issue. Has anyone any idea what may have caused this, and why it would only affect a single website?
