I am not an android programmer but I do have the need for a feature that doesn't seem to exist and I'm curious if its possible.
We are using generic Android 5.1 phones that are embedded into RFID scanners that connect to WiFi to relay scan information.
The RF environment we use them in is as bad as I think it can get, doing an AP scan you usually see 400-600 other SSIDs that are visible.
What I'm trying to ascertain is can an app be developed that turns off 2.4 and specifically only scans a few 5Ghz channels reducing the amount of APs it has to look at before it finds the correct SSID? What we have does work but frequently some of the scanners take several minutes before the lock and authenticate to the right AP.
To much noise they have to filter through. I can configure radios that will lock instantly but of course that kind of control doesn't appear to exist in normal android phones.
Any input would be helpful

Why isn't the relay just routed through a wifi point. Why does it always need to connect to "X Network" when it should always be on that network and just routed to where it needs to go.

Its a closed network, not publicly accessible needs to connect to our SSID to be on the right VLAN and insert the RFID capture data into the SQL.

I have a very unique situation where I need the wifimanager to scan every 10-20 seconds for a new WiFi Access point, and be able to determine by the RSSI value to either stay connected or switch to the stronger Access point.
We have a routed Mesh network, where the AP's all can are DHCP, but they run through tunnels. So during a VOIP call, it would be nice to have the wifimanager be able to scan and handle that handoff. The asterisk server we are using holds the calls as the handoff is taking place, and when using a windows mobile device I have been able to modify an app to make WM6 make the transition in under 5 seconds.
I am in no way an Android programmer, but my client wants to switch to Android, and I need to see what kind of Mountain I am tackling.
The handheld we are using, is strictly wifi b/g no cellular
Thank you in advance for any help you could offer.
WTF!! Anyone know hot to get the tablet to connect to a network with SSID hidden. Tried 3 routers, no deal. Running vegan 5.1, would swith back to TNT if necessary.
Thanks.

I had a similar issue. I have two routers: The westell, it connected to no worries. The Cisco/Linksys I couldn't connect to to save my life. As soon as I let the ssid broadcast, it picked it up and connected. I can even re-hide it again, and it will connect.
I've tried a few ROM's on my Incredible, and the same thing. It connects to the Westell, no worries. But I have to broadcast the SSID for the phone to connect to the Linksys. It turns out Android is somewhat well-known for this. and I believe it to be a system issue, not specific to any ROM or branch.
In reality though, NOT broadcasting the SSID doesn't add much in the way of privacy. A script-kiddie with a WinMo 5 fone can find and connect to them. I used to use my Wizzie to find and connect to WiFi networks when I traveled. Just make sure you are using a secure connection like WPA2 or something.
Tell me about it it drives me insane!!! I'm using a dlink dsl-2740b with/ without MAC filter and i can't get it to find my hidden SSID.
did the kernel mod 2.6.32.28 - from pershoot still no go. Anyone else found a fix?
I'm running an old Linksys WRT54v1.1 with DD-WRT installed...
Non-Broadcast SSID, MAC Filtering, WPA2 -- no issues...
Worked for me right away....on all ROMs (so far) -- Stock, TnTLite, & Vegan...My phone has Cyanogenmod so I'd assume it will work as well...
I'd highly recommend DD-WRT as a new firmware for your Cisco/Linksys if it is a supported model...

I know it's totally not the point of this post but, exactly.
It in fact creates more problems than it does any type of good on any level at all because it makes it more trouble for you, the user to connect to your own network. Some chipsets have issues connecting to hidden SSIDs as well, as shows with the Tablet. Phones can have the problem too. Computers less so just because of the detailed configurations of the software.
You don't even have to be a script kiddie or hacker, there are easily downloaded, well known tools that show hidden SSIDs, along with mac addresses of any and all routers and also which sniff wifi signals. So pretty much anyone that knows more than how to check emails can get into your network if they need/want to and you're not using WEP. WEP is of course only a step up and still simple to get into with just that much more effort (not much, at all).
In these days and times in terms of privacy, if you're not at the very least using WPA with AES then just go ahead and leave it open.
Hey everyone! Back home, I use Touchpad from Nullar (works fantastically) to control my PC and media players when I'm in bed or on my couch. However, I am now at school, and I cannot use WiFi in my room; I can't use Touchpad anymore. Has anyone attempted PC HID control via bluetooth or USB? I tried searching with several different keywords, but I was unsuccessful.
I don't think anybody has managed direct control over the USB connection yet, although we can manipulate it into a few known and pre-installed states (HID not being one of them, sorry). Bluetooth may be possible; we do have at least some access to the BT stack, although since it doesn't support HID natively either it would be quite a hack to get that working.
Are you disallowed WiFi for some reason, or do you just not have a WiFi network set up (and wow, are there really schools that still don't have WiFi in the dorms??)? A WiFi router is pretty cheap these days. Alternatively, it's possible to configure a PC's WiFi adapter to act like a WiFi access point, allowing the phoen to connect to it. I don't know for sure if Touchpad would work over that, but probably.
In theory, Touchpad should be possible over the Internet, though you'd need to open the firewall ports (whcih, depending on your school's network, might not be possible). Ot would lag, too.

Touchpad over WiFi/internet already works. We do have WiFi in the dorms, but the routers are in the lounges (no signal in my room). The rooms have ethernet ports, which is what I use, however we aren't allowed to use a router/hotspot in our rooms because of throttling issues.
Making your PC use the built-in WiFi interface as an access point is probably your best bet. Obviously, lock the network down so it's not going to have other people connecting and getting you in trouble. Do a little searching and you should find the software that does this (there are a few different ones). It was actually supposed to be a Win7 feature, but at the end it shipped half-finished. A few other developers finished it up for Microsoft.

I tried doing this with my friend's laptop (I'll buy a dongle if this works), however my phone (SparkW) doesn't see the network, and when I type in the name manually it doesn't connect. The network was visible to another laptop though.
Did you make it appear as an access point ("Infrastructure" network), or merely cause the PC to create its own peer-to-peer ("ad-hoc") network? WP7 doesn't support that latter kind, but will happily connect to the former. Also, what software did you use? If it was anything that came with Windows, or with any Windows PC, it was almost certainly ad-hoc.

It was ad-hoc with the built in services. I'll try out connectify this weekend and post my results here.
Hi guys,
at work there is a WLAN build with several hotspots at different locations.
When my phone just lays on my desk it constntly loses the connection.
This is because i'm sitting almost in the middle between two hotspots.
The WLANs have the same SSID but every hotspot has a different BSSID
So i guess the nexus thinks "oh nice, same SSID but 5% stronger so lets switch to that network".
The issue here is, i have to login again after every network switch.
So i would like to know how to tell my nexus it shall not switch networks automatically.
Thanks a lot for your advice.
This might be an issue on the corporate side—they might need to tell their controllers to be less aggressive when telling wireless clients to switch APs.
Unfotunately this is not an Option. Huge company with it-security department etc. Nothing get's changed without special permission. So i've to solve this issue on client side

Hi All,
At this point, I'm just brainstorming, and would like some input. (I hope this thread is in the right place)
I'm trying to find a setup to connect to free wifi hotspots that are far away, and share that connection to a group of devices locally. For example, this solution may be useful in a boat or an RV, when you're not particularly close to a free access point.
There are commercial solutions like the Rogue Wave however, this doesn't do anything to authenticate through the Terms of Service (TOS) pages that are frequently used at free access points.
This is what brings me to using Android. There are Android apps which automate the process of accepting the terms of service. My favorite right now is WebWifiLogin (I'm familiar with the security risks involved in using public wifi; and may also have the Android device to also establish a VPN connection when doing this.) (I can't find an equivalent macro-authentication solution that will run on a PC, which would make this much easier.)
So here's my proposed solution:
1. Start with a powerful omnidirectional wifi antenna (Possibly add an in-line amp if needed. Also perhaps a directional antenna may be better for non-mobile use.)
2. Connect the antenna to any Android device that supports an external Wifi antenna. I found several Android TV devices which should work. Like This, or possibly this.
3. Set up some kind of local access point/bridge. One option may be to use fqrouter2 which supposedly uses the same Wifi radio for the local WLAN, while it also connects to the remote one. Another option may be to USB or Ethernet tether to a DD-WRT Router.
Result:
The Android device has a range to connect to a free hotspot up to a mile or two away, then automatically accepts the TOS using the WebWifiLogin app, and shares that connection locally to a handful of devices.
So am I crazy? Is this too complex to work correctly? Is there a simpler solution that I'm missing?
Can anyone confirm whether I've posted this in the correct sub-forum?
Thanks.
I use a slightly different method which yields the same results.
I have a Linksys WRT54GL router (with high gain antennas) which runs DD-WRT and a script called AutoAP. The script scans for unencrypted WIFI access points, makes sure they're live, and automatically connects to the strongest one in range.
I set up a second WPA2 encrypted WIFI SSID in the router which I connect to with my Android tablet. Once WebWifiLogin on the tablet handles the TOS login, the remote access point allows web access for any device that connects to the WRT54GL router (either by WIFI to the secondary SSID or through one of the ports)! This happens because the remote access point usually checks/remembers TOS acceptance by the MAC address of the connected device. Since it only sees the MAC address of my router, anything behind the router now gets access.

This is great information; thanks!
I would not have thought WebWifiLogin would work when connecting through another router. When WebWifiLogin is running, its status says "Listening for WiFi events" (Or something similar) so I was under the impression that WebWifiLogin would only work if the connection to the AP is made directly by the Android WiFi interface, and not through a intermediary router.
This makes things much easier.
