    Hi all,

    I have one of those phones that have the ability to work as WiFi hotspot (adhoc), but as you all know, Android does not let us connect to any adhoc hotspot out of the box, you have to first root and unlock your tablet (which I've successfully done), and then do some tweaking.

    Problem is that all the different 'wpa_supplicant' files that I have tried in my several attempts don't seem to do the trick with the Nexus 7 (since they were tweaked for devices prior to this new tablet) and I was wondering if any of you guys has managed to have the Nexus 7 be able to sniff and connect to an adhoc wifi hotspot (i.e. the nexus 7 accessing the Internet using the 3G connection of your phone). If you can direct me to any webpage that specifically describes the procedure for the Nexus 7, I would be extremely grateful.

    In advance, MANY thanks for any insight you can provide.

    Sounds like you are only trying to tether your tablet to the phone. Doesn't require any hacks on the tablet, only setting up the phone hotspot, which does need hacking if you're trying to do it for free. Once that's done you just connect you're tablet to it like a wifi network.

    Um.. No. I have an unlocked phone and I have a data plan, and the phone came with this hotspot function that allows me to connect my laptop to the internet and use my phone as the "modem" (a mobile hotspot device).

    You said that I don't need to tweak anything in the Nexus 7 to be able to do just what I describe above... How are you certain? have you done it already? Have you seen this being done? You are aware that the Android OS does not support connecting to an adhoc wifi connection, right? (or correct me if I'm wrong and I beg of you to direct me to the page that describes this or let me know how you managed to connect your nexus 7 tablet to your phone and get to the net through it).

    Many Thanks!

    Unless I am misunderstanding you..... You are trying to use your phone as a mobile wifi hotspot, as you have stated. You do not need any hacks on the tablet in order to use the hotspot feature from your phone. As you said, you use it to connect your laptop to the internet, its the same principal. The phone broadcasts a wifi network which you connect to with your laptop, or in this case, your tablet.

    I used my phone (galaxy nexus) as a hotspot just today to activate my tablet when I received it, so yes, I have done this, lol. I activated hotspot function on my phone, it broadcasted a network (I believe called "androidap" by default), I set a passcode for the network, then on the Nexus 7 I selected that wifi network and entered the passcode. It was as simple as that.

    Again, if I'm misunderstanding you then try and clarify and I'll try and help further.

    It seems to me that your nexus phone is broadcasting a regular wifi signal, whereas my Nokia N9 broadcasts Adhoc wifi signal, which does require Android devices to be modified in order to be able to grab such signals.

    Yes it seems this is a more complicated situation. I just spent a few minutes skimming the link you provided and Googling some information on my own, and while it seems it should be possible, unfortunately it's beyond my expertise right now, and its late for me to start learning it tonight, lol. I did see a lot of information in my preliminary searching, so perhaps you will be able to find what you need for this specific request with some research if no one else on this forum is able to assist. Hope you are able to get it worked out.

    EDIT: Even a quick search of the Play Store for "adhoc" brings up a number of apps that could be useful for configuring your tablet as you need it. While I can't recommend anything specifically, you might be able to find something by reading the info and the reviews and combining that with the research you do on the subject.

    Sounds like the issue I had while on holiday with a friend. I had a Nokia phone (5800) with a WiFi hot spot. He could use it from his iPhone or iPad but I couldn't use it from my Android Archos 5! Luckily it supported bluetooth tethering to the phone - poor old Nokia had a hard time. I don't seem to have the same issue now I'm using an Android phone running CM 7.1 - must be creating a different kind of WiFi network. Sounds like you got to the bottom of it anyway.

    Trust me, if I decided to post here, is because I have exhausted all the suggestions that you saw in your quick research with google (as I said, the several versions of the wpa_supplicant file out there don't work with this new specific tablet. Also, what you saw in the playstore are apps to make your tablet be the one that shares its connection (tablets with 3G/4G antennas), which is not the case of the nexus 7.

    I hope one of the experts around these forums might come up with a tested procedure to do this... a Nexus 7 tablet that can only connect on coffeshops or places with traditional wifi hotspots feels like a handicapped tablet to me.

    Have you tried a forum with Nokia folks? I had no idea there was even a difference until you described it.

    Unfortunately, the sheer majority of the users here will have only the "traditional" setup, so for us, that's really the extent of our expertise. There might be one or two here with experience in this field (it's MeeGo, right?), but I would suggest focusing your search from that perspective.

    I have to join in;
    I think there are hundreds of us with this problem. Well, everyone with a Nokia phone. I just don't think people search or post questions using the word 'Ad hoc' and it was only by chance that I thought it best to search for that in google. As of such, I find your post that really does explain the same issue I am having.
    "The Nexus 7 is limited to only connecting to non ad hoc wifi signals. "

    We need an app, solution or hack that allows the wifi settings to search for wifi signals that are classed as ad hoc (a few people call them device wifi's, as effectively, they show up as devices on some computers).

    As the majority of Nokia users, use Joikuspot, it might be a case of asking the team at Joikuspot.

    Alternatively, I am not aware of a way to connect the Nokia via bluetooth tethering to the Nexus 7, either. Does anyone have any instructions for that slower, but temporary solution?

    It's left me feeling lost and a little frustrated.
    I promise, that if I find a solution, I will post it here. Can I ask that everyone else with this problem, does the same. Thanks.

    I had to downgrade my phone to a gingerbread so the phone would tether with 'infrastructure' mode hotspot instead of adhoc only. The nexus 7 is infrastructure wifi only at this point. hopefully someone will find a wgasupplicant file that fixes it.

    Brand new 7 and first time android user. Liking it so far and enjoying tinkering with it. I thought i would add my experience. My Iphone 4 JB/Unlocked 4.3.2(just recently moved to straight talk) and PDAnet WiFi Hotspot work fine. It actually turns the 7 into a really nice GPS (got the holder someone mentioned here or XDA for the car). Not trying to waste anyones time as i am very familiar with Adhoc and networking in general and it might not help anyone limited to only Adhoc network creation via their mobile device, but it is an option on the Iphone and working for me. I think PDAnet has also reworked the network stack for its latest.

    Just got my Nexus 7 and first time Android user and also need to get access to ad-hoc networks. I had no idea that Android can only connect to infrastructure WiFi networks. I have a Nokia/Symbian phone and it creates ad-hoc hotspots using the Joikuspot app; Nokia phones are incapable of making infrastructure hotspots, so I'm limited to using ad-hoc. I've heard about the wpa supplicant file, etc, but is there any solution out there that is known to work on Nexus 7, or Jellybean? Thanks in advance.

    There seems to be a big misunderstanding here. This has nothing to do with the device that is being used for the internet connection - such as OP's Nokia, an iPhone, Nexus, whatever.

    It is clear from the previous posts that the Nexus broadcasts its network connection as an Access Point/in Infrastructure Mode much like any router that you have at home. However, the type of network that we need it to connect to is an Ad-Hoc/Computer-to-Computer/Device-to-Device network. Therefore, the discussion has more to do with the capabilities of the N7 than it does with anything else...hence OP's post. Seemingly, you cannot use an N7 with stock settings to connect to an Ad-Hoc network. Can anyone speak to whether or not a workaround exists?

    Why would we want to do this?
    For those of us who are iPhone users (but N7 tablet users) who have not opted to jailbreak, the only option is to allow tethering is to install an app that circumvents the system - a la handy light or iProxy. These applications require that you create an Ad-Hoc network between the N7/Computer/Laptop and your iPhone so that you can tether. Then through editing connection settings in the browser, you can route the traffic from the N7 through your internet-connected device by using the device as a proxy.

    I'm having the same issue, can't seem to get a wifi tether from my HTC Rezound to my Nexus 7 to work. I've tried several programs for wifi tether to no avail.

    I have been able to get file sharing from my Rezounds ext_sd to my Nexus 7. With both on my home wifi network, I can use X-Plore or another root file manager to get them to see each other.

    But once away from wifi I need to have internet access.

    Any thoughts or help would be appreciated.

    Rezound, rooted, CleanROM 1.7, Amon Ra custom recovery, VZW network. Nexus 7, rooted, stock ROM and Recovery.



    Edit: Found this link: http://forum.xda-developers.com/show...ht=wifi+tether that allowed me to set up my Rezound with infrastructure. Probably this won't work for Nokia, just thought I'd put it out here (and couple of other places) for people to find.

    This is not an issue with the MeeGo platform, nor with the manufacturer Nokia. The issue is Android not allowing (by design) connections to adhoc WiFi out of the box (as usual, I suspect the phone companies have something to do with this). For a better explanation, I refer you to the post above shared by CheckMateMCS where he expresses exactly what I would just end up repeating.

    My sister's Non-Nokia and Non-Meego iPad by Apple is able to connect seamlessly to my Nokia's adhoc hotspot. My brother's non-nokia and non-meego wifi device is able to connect seamlessly to my Nokia's adhoc hotspot. Me not being able to connect is not a bug, is by design on the Nexus 7 / Android side, and me posting in the Meego/Nokia forums would not yield the results that I think would be more effective in AndroidCentral.


    Which brings me to ask once again if anyone has found a wpa_supplicant file, or a procedure that allows the Nexus 7 to connect to adhoc wifi??

    I didn't necessarily mean that it's a problem with those platforms, but rather that you might be better served in trying to find a solution by searching from that perspective, that's all.

    Yesssssssssssssssssssssssssss!!!!!!!!!!!!!

    I have finally managed to have my Nexus 7 access the internet through my non-regular-wifi-but-adhoc-phone data connection!! YAY!! and best of all, I'm almost certain that no rooting and unlocking is needed!! (99% sure of this since my device is rooted and unlocked but nothing seemed to indicate that the solution described below requires it).

    The connection is made possible through bluetooth tethering by using a special app you can download from the Google Play Store for free. So this means you're not even using adhoc wi-fi but a bluetooth link between your phone and the tablet that is established by this app through the "DUN" profile (bluetooth).

    Here are the steps:

    1. Access the Google Play Store in your Nexus 7 and download & install the app "BlueVPN" (this app was developed with Ice Cream Sandwich in mind, but luckily it works on JellyBean making our Nexi 7s 100% compatible.
    2. Both on your phone and in your tablet, do whatever needs to be done to create a pairing bluetooth relationship between these two devices (no need to look for a "connection active" message, just the pairing registered in both devices is enough).
    3. Turn wi-fi off in your tablet.
    4. Execute BlueVPN in your tablet and a list will appear with all the bluetooth devices that your tablet has been registered to will be presented. From this list, select the item that refers to the phone.
    5. Allow for the app to do its thing: negotiating a connection, the handshake, etc... and at the end, you should receive the message that a connection between both devices has been established successfully.
    6. VoilŠ, it's on baby!


    NOW, before anyone starts bit$hing and whining, here are the caveats of this tethering method:
    • Yes, the throughput of data you get with bluetooth tethering is smaller than the one you get with Wi-fi tethering, making your 3g connection feel slower in your tablet (not as slow as browsing on your phone on EDGE, but not as fast as when browsing on HSPA+. You know what I mean?)
    • This connection feeds the internet to your tablet through a "bluetooth socket", NOT a wifi one, and thus, this makes some apps in the tablet "think" that no network connection is present (which is technically true). What do I mean with this? For those apps that only require access to the internet in a straight forward manner, everything will work fine, such as using the web browser app, the facebook app, etc. HOWEVER other apps that EXPECT to receive data through the "wifi socket" will complain saying "not network connection available" like Google Wallet among other specialized apps. One peculiar case is the Google Play Store app: you will be able to BROWSE the store, but you won't be able to DOWNLOAD/PURCHASE apps into your device. As for the two email apps, the "regular email" client works as usual (receiving emails, sending emails, pushed notifications of new emails), however the specialized Gmail client DOES not (hey, you can always use the regular client configuring it with your gmail account should this be something you need).


    To end this on a positive note, the good news is that bluetooth tethering does not consume as much battery power when idle as with wifi tethering, this means, that you can have your phone and your tablet in your bag linked and you won't drain your battery as fast as it happens when using hotspot tethering. And also, the non-requirement of rooting/unlocking I mentioned earlier

    Yes, I'm aware that this may not be a total satisfactory solution to our problem but AT LEAST now our Nexi-7 have the ability to be connected when no wi-fi is around and we only have our phones to the rescue.

    And finally, the disclaimer: proceed at your own risk, which here is practically non-existent, but still, this solution presented here is meant only as informational and I can't be liable for anything that might go wrong, OK?

    Enjoy!!!!!

    PS: Even though this is not a fix but a work-around, the issue still persists on the Nexus 7 side, and I can't take credit for this work-around, as I got to know about it in the Meego forums, just as dmmarck suggested I'd do (still think the fix can only come from the android devs).

    How many of the Bluetooth tethering apps have you tried, because I believe you can get better functionality from a different app.

    Excuse my ignorance of other devices but, can't you enable BT internet sharing out of the box? I have the galaxy nexus and the nexus 7, and was able to use my interwebs on my nexus 7 via BT with my GNex. I've heard you have to turn on airplane mode, turn on BT then make sure when the devices are paired the box in device profiles "use for internet access" is checked. I just paired, checked the box and bam. I wish it would automatically switch when I leave WiFi but oh well. Sounds like you figured it out though.
