Are you using Wifi or 3G/Edge? Looks like the problem is with the admin that setup your Wifi.

Well sounds like you are using their DNS servers and someone blocked gmail.
go to opendns.com while tethering to change your settings if you can. You should see a "dashboard" link at the top right of the page.

OpenDNS is an alternative DNS service (normally DNS is provided by the ISP). Wifi-Tether-For-Root by default has OpenDNS hardcoded in as the default DNS (instead of T-Mo's DNS servers). Since all traffic on T-Mo 3G is routed through their central server, regardless of where you are physically, your ip on the internet will appear as coming from a T-Mo data center in Missouri or Kansas or something. Perhaps someone has maliciously set up an OpenDNS account with this ip and locked out gmail.
Edit: I am having no problems getting to gmail using WT4R. My tmo ip was different from the usual though. Perhaps they are load-balancing their US network. Last time I checked, my tmo ip came out in Kansas. This time however, it came out of Rhode Island. Strange, considering I am physically in California.
Could you lookup your internet-side ip address while tethering and see which tmo datacenter you appear to be coming from when your gmail access is restricted?

This is the first time I've ever used wifi tether. Was kinda wierd to see gmail was blocked. Working on setting up an opendns acct now.

Ok....I'm totally lost now. I've got an opendns acct setup. I'm lookin at the dashboard thing, and have no idea what to change to fix this issue?

You are going to want to go here https://www.opendns.com/dashboard/settings/
It should show your current IP in the drop down.
Turn off the filtering and make sure nothing down below is added.

Easy enough to figure out my ip addy....but no idea how to do the rest.
Weird thing though...I signed up fro an opendns acct, browsed around a bit in the dashboard and now gmail works? ~edit~ nvermind, spoke too soon...gmail is blocked again.
For some reason I have a problem wrapping my brain around this kinda stuff.

your ip could have changed

I see my IP under the network tab. Under the settings tab it says "to control your settings, you need to add a network to your account." If I click "add a network" it takes me back to the network tab where my ip is displayed. If I click add network, it says network already exists?
Bleh....

Like i said, T-Mo is likely load balancing across their many gateways. My guess is whoever locked gmail out only did it to one of the gateways. Your best bet is to change the DNS servers away from opendns.

The reason is because only one openvpn account can control a network. Whoever has messed up that tmo gateway has full control of it until that person or openvpn changes the situation.

It might be enough to edit /data/data/android.tether/conf/dnsmasq.conf with a text editor and substitute out the DNS values in there with your own DNS. I'll try it out later.

"wifi tether" should update the dnsmasq.conf-file automatically (will take the dns from your 2G/3G-connection) - this was introduced in version 0.95.
Type ... "getprop net.dns1" into terminal ... that should exactly be the nameserver in dnsmasq.conf (after you have started tethering).

Bleh....I need a break from phone tweaking for a bit. Buuurn ouuuut

Works for me
I just got home, tethered just to see if it would affect me too. Not problems at all.

harry_m is right. When I tethered to my G1 via WT4R (ver 0.9.6) and visited opendns.com, it showed the "Start using OpenDNS" button, indicating my currently used DNS was not OpenDNS. I verified that WT4R had fetched the G1's internal DNS setting by checking the dnsmasq.conf:
Code:
$ su
# cat /data/data/android.tether/conf/dnsmasq.conf
no-resolv
no-poll
server=10.177.0.34
server=10.176.80.242
I suggest you reinstall WT4R and choose no when it gives you the option to import old settings. This way, it will build your configuration files from scratch (and not use OpenDNS).

WiFi DNS Does not Update

I've posted this over at the Rhodium Thread located here:
http://forum.xda-developers.com/showthread.php?t=731292
but haven't gotten a single response yet. Since this is a concern for more than one device I feel like I should post it here. Mods feel free to move this to the correct location if need be.
===================
So it seems to me that this is a problem on ALL Android devices that I have tested with. Here's the situation
I have a router in my house in which I have DHCP turned off so my device will grab an IP (Not Static) and DNS from the ISP. I need to find a way to be able to just change the DNS Settings to 208.67.222.222 and 208.67.220.220 on android without having to manually put in an IP since the IP will automatically get changed every few day's.
Android doesn't seem to let me do that. Does anyone know how? Going into the Advance Menu in the Wifi settings and changing the dns does not actually change anything... I noticed this on the following android devices as well: Moto Cliq, MyTouch 3g, old Kaiser running android on NAND, and my Rhodium Devices running android.
Any reason as to why Android isn't updating my DNS Settings? Any help would be appreciated.

Ok so DHCP is assigning your network config, but you want to use different DNS servers than the DHCP allocated ones?

On my HTC Hero running an Android 2.1 ROM, unless "Static IP" is selected, I dont even get the option to change the DNS servers (option is greyed-out).
One way to manually change DNS is via shell if you have root access on your phone using ADB shell (or ssh, telnet etc if your ROM supports them), see this thread [Q] Help! Changing DNS settings .
Any network config tools on the app store?

I'm confused by your question. If you have DHCP turned off your device's are not going to grab an IP address from your router. Why don't you turn on DHCP and let your router assign IP addresses. As doing so your devices will also use the DNS setting from the router which will be your ISP's DNS ip address. Unless you change your DNS settings in your router to one of the many public DNS servers available. My recommendation is turn DHCP to "ON" on your router. Maybe start your DHCP IP assignment at 192.168.1.100 and go up to 150. That way you can use the range from .2 to .99 for static IP's. This is how I configured my router but I'm also using DD-WRT firmware on my router which highly customizes the router. Alternately you can change your routers DNS ip setting to Open DNS server so there would be no need for you to change it on the phone if you are using WIFI. Just let your router do all that work for you. Hope this helps. Viva Santiago Rep Dom y NYC.

[Q] DNS/Network interface settings in WP7

Hi there,
I'm currently searching for a registry entry or hosts file on WP7. I know there are some registry keys for DNS on Windows Mobile 6.5, due to its support for multiple network devices (see http://msdn.microsoft.com/en-us/library/aa916390.aspx). But if I'm looking at my HD7 with Advancedexplorer, I couldn't find any of these keys.
Only interesting infos where in HKEY_LOCAL_MACHINE\Ident, but I'm aiming for the keys or file where WP7 will keep its setting it gets from DHCP while it is connected via WLAN.
AFAIK there is no possible way to manually edit the network settings, so I'll always have to use DHCP. Do someone of you know the location of this information?

Oh, I see my post was moved to Q&A? Thought it would be more a hacking/development problem to find the right file/registry key? Is it possible to move the post back to its original area?
Ok, after digging, I found finally the location for the Wifi Interface settings:
HKEY_LOCAL_MACHINE\Comm\BCMSDDHD1\Parms\Tcpip
I'm currently not connected to a Wlan, but will recheck at home if there is a value for DNS or device IP
Little Update: if the phone is connected to Wlan, you will get more options beginnen with DHCP I think. So its no problem to change the DNS, but it will only last until the phone reconnects. The values will be overwritten. If you enter a wrong non working DNS, the phone will resort to your providers DNS.

IP address changer

Hi,
exist some HOMEBREW app which can let me change the IP address ?
Somebody told me that it exist.
Thanks.

Well, you can easily specify your own IP address for WiFi networks. That's built into the phone.
For the cellular network... I'm not aware of a way, though it probably does exist. I'm not sure anybody has coded it as a WP7 app, though.
Why do you need to do this? Your IP address quite probably changes every time you reboot your phone; why do you need it to be a constant value?

For me this threat is also interested. And why would be practice to be able to put static IP address is simple, what to do when you want to connect in WIFI environment where is no DHCP.
Or let say ISP, give you STB with WLAN on which is not enabled DHCP.
Cheers.

As I said, specifying your own IP address is easy on WiFi (specifically for networks without DHCP). Open the WiFi settings page, press-and-hold on a network, and select Edit. If you connect to a network that doesn't have DHCP, it should prompt you for the settings when you first connect.

My friend, this what you are wrote is written in user manual which I am get with my optimus 7. There is also written that is procedure for connecting on hidden network is press-and-hold on any wlan net and change the name according with hidden net and I could not reach hidden net until I am receive latest fw(few days ago) and I have optimus 7 almost nine month.
In any case, what you are wrote not applies for optimus 7, maybe for some other phone apply, but not for optimus 7, at least with OPN Firmware.
Cheers.

Ah... I don't have an LG phone, so if there's some weird quirk to their WiFi drivers, I can't help you with that. Sorry. :-(

JosipoGo, have you connected your phone to Zune and done updates that way? Go to Settings=> about phone and tell us what version of OS you have.
I am thinking you may be running NoDo on your phone, as anything with Mango or above should have the ability to change IP address. Yes, your shipping firmware (if it is NoDo version) may not have this feature, and it wouldn't be on your phones manual if that is the case.
If you have never done system updates, you should be able to add this feature by preforming the Zune update (if an update is available for your phone).

ICS STATIC IP- How to setup up your static ip.

I figure i would post this in the General section, as this might help others that may need help setting up their static ip .
Here are the steps to set up static ip for anyone needing to do this.
1. go to system settings
2. click on wifi
3. click on add network
4. enter your network ssid
5. choose your security
6. enter your password for you network
7. click save
ok here is where you have to let it find the network, let it connect and aquire an ip address (even thou it is not the correct one) let it do its thing. do not skip this step otherwise you will not be able to configure the ip or save it.
once it says it is connected go back and do steps 1-2
you will see your network and it should say connected.
long press on your network name. it will bring up 2 options.
1 forget network
2 modify network config.
click on modify network config
it will bring up a bunch of settings. scroll down till you see a box that says :" Show advanced options"
click on the box. ( do not save or cancel the window)
scroll down a little bit and you will see 2 boxes
1 proxy settings
2 ip settings <<< click on the lower right hand coner and change this from dchp to static.
once you do this you will see settings under that box input all your info into these boxes *****( leave 3rd box that says " network prefix length" at 24 )******* once you have completed click save and your phone should be connected to you static ip network..
1 ip address
2 gateway
3 network prefix length (Leave this at 24)
4 dns 1
5 dns 2
6 ******* CLICK SAVE ********* not cancel or you will have to repeat the process. LOL Dont ask how i know this 3 times.. LOL
I hope this helps everyone. Sorry for putting up these instructions late, but unfortunatlly i got a little busy trying to fix a loss of root.
If this helped hit the Thanks button.

I would recommend that anyone wanting to get a "static" ip address go into there router and tell there router to set the ip from the mac address. A little of work because it depends on how to do it from router to router but works well in dd-wrt.
You can find how to set static leases in dd-wrt under the "services" tab. This simply allows you to keep your phone a dhcp phone when abroad while keeping a specific ip while at home. In fact, I get the mac address of every device on my network and use this table to set my house statically without having to do anything on the device itself. Comes in handy to know what devices have what ip and therefore and easy way to keep on top of your network security.

^^ that's what I do too.

I also do this. With 10 devices connected and 4 of them I need to know the static address for things to work properly. I can't imagine setting static on each device. Its like a 3 click process via my router regardless of what OS the device is running.

Save static IP in Galaxy S2 ICS
Hi,
After many tries I've found that in order to save a static IP WIFI entry in a Samsung Galaxy S2 under Ice Cream Sandwich you need to fill ALL fields, even the "Network prefix length" field (whatever that is).
So, even though it shows "24", that field is actually empty. Just enter all your IPs plus 24 in that field and you're done.

I'm assuming 24 refers to /24

or 255.255.255.0, which is the subnet for a Class C network and the default network in most home home routers that assign DHCP.
*However* - depending on how you like to manage your own home network, starting from your router, it doesn't necessarily have to be a /24 network. Yes it's more work, but it's not the only option.
(At least I think I'm right. Cisco courses were several semesters ago. ;p)

The "24" left untouched works fine on my SR on UCLE2. What "that is" is the bit length (measured by 8 bits per dot-delimited octet) of the network label portion of an IP address. Where 192.168.1.XXX IDs the network and the Xs are available for node IDs or endpoints. The first 3 octets there are a 24 bit prefix.

On SR and Cappy in ICS I have found that default entry holds when appropriate. What did you mean "Just enter all your IPs plus 24 in that field and you're done." ?

That will work equally. The 255s indicate the potential node IDs in octets 1-3 are blocked as part of the network ID and the 0 in the 4th octet opens all (255 potential node IDs for assignment) in this subnet mask.

On my friend's Xperia Active, that just got updated to ICS, I also tried to quickly input some fields under advanced menu to see if the WiFi would work.
Boy was I wrong!
I had to delete my old WiFi connection, then I had to follow these step-by-step instructions and I had to fill ALL fields in one stroke after pressing "Save". Only then the WiFi worked normally, else it wouldn't transmit data over the internet.

When i try and connect the save button is not pressable.

Well if you followed the directions correctly then you should be able to connect. I have done it this way over and over everytime i change roms, and it works everytime.
Sounds like u are connected to a ghost ip address that says u are connected but not connected to the real ip address. If you have your router setup with a static ip address, then these directions will work. If you have it set to dhcp on your router than all you have to do is set your name, security,password and then the phone should do the rest.
