HOWTO: Set up your G1's Wi-Fi (in order to make it actually *work*)

I've received my Dream yesterday and the wi-fi is painfully slow. At first it didn't work at all, so I entered all settings by hand, assigned it a static IP address and other stuff. Then it worked, albeit very slowly. So, here's what you need to do if your wi-fi isn't too fast.
Go to Wi-Fi settings, press Menu and select Advanced Settings. On your computer (if you're using an unix based OS, at least - can some Windows guru help me out with this?), get to a terminal emulator and type:
Code:
ifconfig en1
This should give you output like this:
Code:
Wiktoria:~ Nekkoru$ ifconfig en1
en1: flags=8863<UP,BROADCAST,SMART,RUNNING,SIMPLEX,MULTICAST> mtu 1500
ether 00:1c:b3:bd:b9:cb
inet6 fe80::21c:b3ff:febd:b9cb%en1 prefixlen 64 scopeid 0x6
inet 192.168.55.102 netmask 0xffffff00 broadcast 192.168.55.255
media: <unknown subtype>
status: active
Wiktoria:~ Nekkoru$ [CODE]
The IP address after inet (192.168.55.102 in my case) is what you're after. On your phone, enter your IP address as the IP adress you got, with the last block changed to anything that's not being used on your network. I assigned 192.168.55.69 to my phone, because it's easy to remember and it's kind of childish.
Now, your "Gateway" should be your router's IP address. Your router's IP should be specified in it's manual - or your system settings. Your subnet mask should always be 255.255.255.0.
We need your DNS settings now - this is where most of us screw up and this is what you need to fix the most. Go back to your computer's terminal and type in
[CODE]dig
Look at the bottom. You're interested in a line that says "SERVER: xxx.xxx.xxx.xxx". That's your primary, first DNS. If you give that to your phone, your wi-fi should work way faster. Set it up as the second DNS as well, unless you know a better DNS server than your ISP's (anyone?).
I'm sorry this got so complicated, but that's the best way to set up your G1's internet if it gives you any trouble. I hope I helped somewhat.

[SCRIPT] Change Hostname

No credit to me please.
I modified the script attached in http://forum.xda-developers.com/showthread.php?t=1366934, for LG Revo.
I merely changed /bin/hostname to /system/xbin/hostname, which is the correct path to access the hostname command in GingerVolt 1.3
Run using script manager, (su and on-boot).
Why change hostname ? Well by default the hostname is something like 'android_<IMEI-NO>', which is way too long, and makes it difficult to spot your device in your routers 'attached devices' log.
Change the "LGRevo" in the line "devName=LGRevo", to what ever hostname you like.
Code:
#!/system/bin/sh
#change devName to whatever you want.
devName=LGRevo
if [ "$(/system/xbin/hostname)" = "$devName" ] && [ "$(getprop net.hostname)" = "$devName" ]
then
echo "Device hostname does not need to be changed."
else
echo "Device hostname is being changed to $devName."
/system/xbin/hostname $devName
setprop net.hostname $devName
if [ "$(/system/xbin/hostname)" != "$devName" ] && [ "$(getprop net.hostname)" != "$devName" ]
then
echo "Device hostname has not been changed."
else
echo "Device hostname has been successfully changed."

Nice find, just a quick question though.
Is there any way you could elaborate a little more on this? Why is shortening the hostname and making it easier to find in the "attached devices" log important?

More explanation on why change the hostname....
As of this writing I have about 6 android devices connected to my home wifi router. Most wifi routers have a page which shows the details of attached devices. This helps you to determine if any unwanted device has managed to hook on your wifi etc.
With the default hostname like 'android_<IMEI-NO>', the list of attached devices is hard to de-cipher. So changing the hostname enables me to make some sense out of the 'attached devices' page. I know exactly which device has hooked to my router.
Secondly, on my router's config, I have assigned static DHCP for all these devices, and also entered them in the DNS. That way each device can talk to another if needed, say over 'SMB' / 'SSH', simply by using the other device's hostname, w/o having to remember each devices IP.
Makes sense ?

Oh ok cool! I never even thought of doing it so it's easier to check for unwanted devices. Very nice find, thanks!

About A-GPS Servers (gps.conf)

Hi there,
Galaxy SIII has "XTRA_SERVER_1=http://gllto.glpals.com/4day/latest/lto.dat" server line in gps.conf file, while Galaxy S has "XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin".
What is the difference between those servers? And which is better for faster GPS fix? Or "XTRA_SERVER_1=http://gllto.glpals.com/4day/latest/lto.dat" server is compatible with I9000?
Thanks in advance.

no answers?

They're different servers, that said, they're interchangeable. Why don't you try interchanging them? Remember to back up.
Here's mine, it's the fastest in my country:
NTP_SERVER=0.ca.pool.ntp.org
NTP_SERVER=1.ca.pool.ntp.org
NTP_SERVER=2.ca.pool.ntp.org
NTP_SERVER=3.ca.pool.ntp.org
NTP_SERVER=ca.pool.ntp.org
XTRA_SERVER_1=http://xtra1.gpsonextra.net/xtra.bin
XTRA_SERVER_2=http://xtra2.gpsonextra.net/xtra.bin
XTRA_SERVER_3=http://xtra3.gpsonextra.net/xtra.bin
# DEBUG LEVELS:
# 0 - none, 1 - Error,
# 2 - Warning, 3 - Info
# 4 - Debug, 5 - Verbose
DEBUG_LEVEL =0
ACCURACY_THRES=5
INTERMEDIATE_POS=0
ENABLE_WIPER=1
SUPL_HOST=supl.google.com
SUPL_PORT=7276
REPORT_POSITION_USE_SUPL_REFLOC=1
# blank

xtra.bin is basically used by QUALCOMM , lto.dat is used by Broadcom Chip of BCM47511. Do a whois on glpals.com and gpsonextra.net and you will know which company uses which services. There is no great idea to change the Software of GPS to Qualcomm from broadcom ...

Gps-nitz-ntp
Hi all,
Sorry to post there but after lot of search, i haven't get any information
Does NITZ protocol is used only by GSM network and is it the default protocol used by android system to sync time?
Things I know is that:
- user can't set time without root privileges
- NTP server could be used only with third-party apps
- there is a gps.conf file in /system/etc and inside there is a line NTP_SERVER=... I want to know the meaning of gps.conf file cause my final goal is to try to sync device with NTP server wihout root priviledge but by redirecting NTP request to my own NTP server (changing DNS maybe) I used some packets sniffer and I can't see some NTP packets (over Wi-fi or GSM)
Thanks fo help

[Q] (Problem) Make Raspberry pi share internet via Ethernet (Filter)

Greetings,
I use Raspbian.
I come over here, I'm a beginner, and I would like to ask for help on an issue (draft) I'm doing.
Explained below:
First of all I have Raspbian in my Raspberry Pi, then I want to do is set this as a network node to monitor through "dumpcap" packets that pass through my network, I've done I installed everything necessary in fact I've already running great, I've done through a Wireless (USB) adapter from functioning as "Access Point" wireless (so will download the files to be saved), I've come this far following this tutorial: (Photo Attached) and another pair.
The fact is that since I could configure all my peripherals, the problem lies in the following:
I need to connect from my local home router or from the Internet source (ADSL Modem), through an Ethernet cable to my Raspberry Pi (which work to record all packets My network traffic by "dumpcap") it is noteworthy that this will have perfectly configured, then I need through another Ethernet cable which my computer (PC) will be connected by a transformer USB-> Ethernet (attached reference picture), for example, that I have done and the only mistake that happens to me is that my PC does not receive Internet remains limited, in theory I need to do is that the Raspberry Pi function as a filter through which to capture packets of dumpcap store in some files (this is already done), but then the computer will connect by USB-port Ethernet continues to have internet and work perfectly as if connecting from the ADSL modem to the PC directly.
Could anyone help?
Thanks in advance.
