wifi problem

There are 20 wifi-devices (all free accesable) with strong signals around my house. My device gets connection only with 1 device which has very weak signal. All other devices (with strong signal) are not accesable. I get the error message "Unable to obtain Server Assigned IP address". So I can't make a connection (for internet).
Any idea what the problem is and how to resolve this?

Try to set the Power Save Mode setting to Best performance. Is it helpful?

Probably, there is no dhcp server in the network...
You have to contact the network's administrator and ask for an ip address, then set it manually.

Proxy Setting on Wifi

I cant seem to connect to my office network because we are working behind a proxy and the G1 does not allow to enter a Proxy name!!!!
is there a way to enter a proxy name and port number in the browser or in the system. It can be done for APN but not WiFi!!!

Any suggestions!!!!

Hi Shobbow
I noticed this too, since i was trying to run all my traffic through a secure tunnel to my home computer.
I believe you need to use something like this

hopefully the route application should be able to route all traffic?
Let me know how you get on since this would be interesting if you can do it

Fuze - VPN to Compnay Network - Remote Desktop Works, Intranet browsing does not

I have the AT&T Fuze with the stock ROM. I purchased it the first day it came out. I think this was 11/11/2008. I have the PDA Personal plan for unlimited data. I have things set up so that my contacts and email synch with our Exchange server. I can remote desktop from my Fuze using the data network to any machine that I can remote to from my computer, so from that, I am thinking VPN must be configured correctly. On one of these machines that I connect to, I have IIS running and put a very simple web page on it (no script, nothing IE specific). From my work computer, it loads fine. I can remote desktop from my Fuze to any machine on the network and launch IE and load it. But, I can't load it directly from my Fuze in either Opera or IE. It does initiate the VPN connection. But, then I get the error HTTP gateway timed out. I'm really not interested in viewing the page that I created. We use Perforce, which is source control system. It has a jobs portion, which we use to track bugs. There is a web interface to the jobs, which is on the intranet, not internet. I don't have rights to remote to the Perforce server, and that is why I initially tried putting a simple page on a machine that i am an admin on. I want to be able to click on a link in my email and have it load the bug in Opera. If I am home and turn on WiFi, and disable the data network, this works fine. This bypasses AT&T's machines, which makes me think there is something that AT&T is blocking. And if they are, then maybe it is the AT&T bloat this is telling them what it is. Our IT guy has verified that I am successfully VPNing in. He is seing the mycingular.net in the firewall.
My boss has the same phone, but purchased more recently, and his is working fine for this. He has flashed the new AT&T test ROM, and done the thing that keeps the AT&T bloat from getting installed.
The fact that remote desktop works, but browsing a webpage on the same machine does not, makes me think there is more to this than just network settings.
If anyone has the anwer to this, please share. If I find the answer, I will post it is well. I have extensively searched the forum for the answer to this, and have not found anything that worked. If I have missed something, I appologize.

Sort of works now, still have an issue
After going to the proxy tab, and checking that This network connects to the Internet and checking the check box that this network uses a porcy server to connect to the internet. Then specify the server. Then go to Advanced and change the HTTP port to 8080 instead of just 80. I also put the user id, password and Domain in on the proxy for HTTP.
But I get prompted for a user id and password from the proxy erveer. I have entered it and clicked the checkbox to save it. It does not display the same info that I entered the next time and it does not display what was entered on the HTTP proxy page. It is a drop down, and I can select the correct one. It's just annoying to need to. I'd like to clear this cache.
Also, to initially get it working I had to disable HSDPA and HSUPA, restart. Then reenable it. I have the registry on my Fuze which give me the menu option on the Advanced network tab to do this.

Figured out how to clear the cache issue - still prompts
The cache was a setting in Opera for passwords.
It still asks for the password. At least it is prefilled with the correct info, since I now only have the one entry, so it is just 1 click, but I should not need to do this step.
Any one know what I need to do to fix this.
If I try to load it in IE, it just tries but never succeeds and never asks for a password, just says Opening.

Connections
Why should I need to set this to connect to the Internet, and use the ISA server? I would think if it needs to connect to the internet, it should be able to just use the Media Net
My Media Net Settings are
Modem -
Name - Modem
Media Net - wap.cingular
Advanced shows the modem in the drop down list as Cellular Line (GPRS, 3G)
The drop down is disabled
Next
Access Point Nam - wap.cingular
Next
User name - [email protected]
don't know what the password is. I've never changed it.
Domain is blank
Next
TPC/IP
Use server - assigned IP address is selected
Use software compression and use IP header compression are checked.
Use slip is not checked and the checkbox is disabled
Servers
Use Servr Assigned addresses is selected
So DN,Alt DNS, WINS, and ALT WINS are disabled.
Proxy Settings
This network connects to the internet
This networks uses a proxy server to connect to the internet is not checked.

More info and additional question
Navigating to some intranet sites does not prompt me for the isa server.
such as http://machine/virtdir/Default.aspx
seems to work without being prompted
but
http://perforcemachine:8080/@md=d&cd=//&[email protected]//?ac=107&mx=25
prompts me for the password.
Also, in order to get either of these links to work, I need to have in my exceptions:
*.companyname.com/*
Where companyname is the actual companyname.
This is annoying because it makes it connect to the VPN when synching with the exchange server. Before I want on the quest to get these links to intranet sites to work, I synched with the exchange server without connecting to the VPN.
I've tried putting in isa.companyname.com in the exceptions, but that doesn't work.
Is there a way to do *.companyname.com/* except mail.companyname.com?
I suspect all of this is in the registry somewhere.

Proxy at work does not work on FUZE

I tried all the options but no avail:
Disabled proxy with builtin cab
Used Advance Config Tool & Diamond Tweak to disable 3g
Increase Power to WIFI
Enter the proxy credentials properly
Select WORK in the connections
I am connected to the network through the WEP key. I have an IP address.
But the thing the intrigues me the most is that I cannot hit outside with Opera or IE unless is the Intranet. BUT, I can hit my comcast email throught the email tabs>inbox>send receive. This email account is from the outside. How the hell? The network guy said that I have all the credentials properly entered and that I should be hitting outside throught the proxy. What gives?

Ok, so I got it to half of it to work.
Disabled proxy through CAB
Enter proxy credentials to "My Work Network"
Network adapters>card>"the internet"
SSID>Connects to>"work"
Applications that use internet connect with: My work network
I can connect to the internet outside now, but I cant update my email accounts that are in the outside. Only if I change my SSID to connect to the internet, then email works again, but internet doesnt.
Anyone that has gone through this crap please post something.
Thanks.

Well, I knew it was to soon to scream victory.
It now appears that I have to have IExplorer running in the background to be able to surf through Opera and use Google Maps. If I dont have IE open, then I get prompts from the proxy in Opera and Network problems in G-Maps. This is just too freaking weird. What shagging combination is going to make everything work!?!?!?!?!?!?!

Hi...!!! May be there is some problem with your setup. I had also faced such problem. Here i will guide you with a simple configuration sets for HTC VPN
Add a new VPN connection:
Step # 1:
- Tap the Home icon, tap Menu, and tap Settings.
- Tap Wireless & networks.
Step # 2: Tap VPN settings
Step # 3: Tap Add VPN
Step # 4:
-Select the type of VPN to add (PPTP, L2TP, L2TP/IPSec PSK VPN, L2TP/IPsec CRT VP)
Step # 5:
- Enter VPN details such as VPN name, VPN server, etc
(The said settings will depend on the type of VPN protocol and the respective VPN Service you want to setup on your device)
Let’s Try L2TP VPN Details:
VPN Name: Name it whatever you want, e.g. VPN 1
VPN Server: IP Address or Address would be given to your by your VPN Provider or Network Admin.
L2TP Secret: It will be given by you VPN Service Provider or Admin. It’s secret security key to ensure that we are connecting to the right mobile device and server.
Leave DNS Search Domains as it is. Save the settings and move back to home screen.
Connecting to the VPN:
- Tap the Home icon, tap Menu, and tap Settings.
- Tap Wireless & networks
- Tap VPN settings
- The VPN connections which you have just added will be displayed.
- Tap the VPN through which you want to connect.
- A dialog box will open asking for your credentials, put in the details and tap again.
- When connected to a VPN, you will see an ongoing notification in the Status bar on your phone. If you should get disconnected, you will receive a notification and an option to go back to the VPN settings.
Disconnecting from the VPN:
Simply open the notification panel at the top of the screen on your phone and tap on the VPN notification then tap again to disconnect.

I apologize for reaching you a bit late...
Actually i had also faced such kind of problem then i configure it somehow.
And i am pretty much sure that you are either entering wrong user name, password or server name. I mentioned server name / address because it is the main problem which user facing at the time of setting up the vpn on their devices. So kindly try to configure it again with the correct details or you must contact t the concern VPN Provider regarding the same.

same problem
Hello,
I have same problem on MY HD2 with CM rom. Lot of tries but with same result.
I am able to connect, receive IP from pptp server and also I can ping routers LAN IP. But that's all. I am not able to ping other address from LAN. My Vpn setting on hd2 always shows "connecting" and connection crash after 10 sec. I thought it is problem on my router, but maybe not. Behaves it similarly for you?

Hello,
I have fixed permissions to /etc/ppp/ip-up-vpn to 777 and vpn pptp works perfect for me
