If you are connecting by a modem/router then in the firmware you can set one of the devices on your network to use it's MAC address so all devices appear to have that Mac address. As for changing the Mac address from withing the phone, don't know how it can be done or even if it can be done as I suspect the address is fixed to specific hardware.
It can be done, but I doubt its legality. It has to do with messing around with mmcblk0p3 iirc

I rarely post questions because most that I have had have been answered already and I can find what I need through searching.
However the amount of apparent confusion in the questions and answers on this subject has made it impossible to figure this out.
I cannot reliably connect via wifi on my Wizard running XDA Mobile 6.
Problem:
1. Wizard connects to Wifi, but does not correctly get DHCP.
Okay, a pda is pretty useless as a wifi device if it can't receive a dynamic address, but I set up a static IP (on the Wizard) to work with my router, and deferred diagnosing this until after I actually have wifi working at all.​2. Wizard cannot seem to choose a DNS server.
It apparently tries to use the GPRS dns server to resolve addresses, and can succeed, but this is slow. If I disable the phone it uses the DNS I entered (my wifi router). and works precisely as it should, resolving domain names almost instantly, just like the other wifi devices on my network. With the phone turned on the DNS address seems to be ignored​
Is there someone out there who can address this problem? Maybe I need a primer in the serpentine methods Windows Pocket PC uses to configure itself to connect to networks, because it certainly doesn't seem the least bit logical from this writer's perspective.
Thanks.

Yes, I had the same issue with most 6.0 ROMs here. But TNT 6.0 ROM works without changing DNS manually. Haven't checked the root cause is ...... You might install TNT ROM to see whether it resolve your issue.
That's some kind of DHCP problem.
I don't have it with my cooked ROMs.
When DHCP is used to get an IP address, it also gets the DNS servers sent back in the same response packet. So if you disable DHCP (or it fails) you need to manually configure both it and the DNS addresses.
Exactly my point.
It's clear that the problem is a DHCP client failure. There are plenty of posts here saying things like, "try a different ROM" etc. The information I am looking for is how to fix it.
Uh, try a ROM that doesn't have the problem?
The ones I've run (including my own cooking) work fine.
oops- double post
I was sort of hoping for a registry key to edit or other setting...
DHCP is working, for example on Remote NDIS-host (activesync connection), so it seems likely that there might be another solution.
I will have a look at your ROM, Genesis3.,
I have been trying to spoof my mac address on my phone. I am a pen tester so please don't lecture me on the ethics behind this because I know. It is very simple to do on linux, so I thought it would be possible on Android.
I installed busybox and terminal emulator and ran the su command. So far, i can run 'busybox ip link set eth0 address XX:XX:XX:XX:XX:XX' 'busybox ip link set eth0 broadcast XX:XX:XX:XX:XX:XX'. Everytime I do this, it changes the mac address, but breaks the wifi functionality. The only way to fix the wifi was to disable, then re-enable it, but that resets the wifi. I was wondering if we could colaborate on this and maybe get somewhere.
I have also seen this somewhere, but am not sure if it will work.
ip link set address NEWMAC dev eth0
Sorry for digging out this old thread, but I was trying the same and failing in the same way as you were.
The only difference is, I do not change the broadcast address, because imo this should remain on "all FF" (please tell me, why the broadcast should be set to the new MAC).
If I change it and fire up 'ip link show eth0', it shows the changed MAC.
The settings menu still shows the real MAC.
As in your case, the WiFi-connection (naturally) terminates (the router (access point) cannot know about the change). If I try to reconnect to the router, I get the error that my password is wrong. When checking the router's log, I see an entry about a failed connection attempt from the changed MAC address.
The only explanation I have is that the WPA2 encryption somehow incorporates the actual "real" MAC address so the encryption fails and as a consequence the connection is refused.
So-far, I haven't tried it without encryption.
Another question would be, what exactly is executed, when you activate WIFI on the phone? Which script?
I know that the network device (in my case "eth0") is created at this point.
If WIFI is down, no such device exists.
I would suspect some script that creates the interface, activates it and starts a demon that handles the connection stuff.
Maybe it would help to inject the spoof code after the interface was created, but before it is activated? So-far, I couldn't identify the correct script/command. Does anyone know?
Knowing the command that creates the network interfaces would also help when searching for the script.
Just got my Samsung Captivate about a month and I got my wifi connected to the school network, but when i open the broswer or any apps need internet i didnt get any connections? at the first week it works.. and when connecting to the school wifi it should be come out with the school login page,, then the internet will work.. however the wifi is connected doesnt matter how strong the wifi singal is.. it just cant load and cant bring me to the login page..
I really need help..
and the wifi works everywhere.. except my school...
btw my friends iphone 3gs works..
I am also at college and have had the same problem. the best reason I have found is the phone itself. half of our wifi is an older standard that does not work on the phone. it shows up as wep and i can not get it to recognize it as 802.1x . in my tinkering I have also messed up the wifi that was working.
long story short it probably won't work. I have spent a long time trying to get it to work with no luck

Hello to both of you,
I also attend a college with an 802.1x connection and the captivate supports most of these networks; however you will probably need to configure the network settings manually (usually retrievable on your schools IT site). If you dont mind digging up your settings I would love to check to see if I can configure your phone.
FYI, you might be having a problem similar to what's seen in this post.

I definitely had this problem today. It appeared connected but no web pages would load. Going to have to investigate further. Why can't things just work
I know my school recently implemented some new security certificates that you must agree to before logging in, has anything like that changed for you? My wife's Aria is running 2.2 and can log into the school network, but my captivate cannot. It is frustrating I know.
Seems some colleges and universities are noticing issues with android devices letting the DHCP leases to expire but keeps using the IP address assigned instead of requesting a new one.
See the following links.

I actually have similar issues with my Belkin wireless router at home. My laptops and other wireless devices have no problems connecting or re-connecting but the Captivate just refuses to re-connect after the connection was terminated. Even after resetting the router, the phone just keeps trying to use the same IP address for some reason.
The only way I could get it to reconnect is to either reboot the phone or to remove the AP entry which is a pain especially if you have wireless passwords.
Hopefully someone with better insight into how Eclair and Froyo handles WiFi can come up with some fix.
more solutions?
I believe the new 2.2 firmware solves this issue. I too am at College and my captivate FAILS to actually access the internet through wifi unless I statically assigned the IP.
I just updated to Froyo and it connected instantly. I'll have to do more testing to make sure, but I think Samsung finally fixed it.
captivate wifi issue at school
i just got Galaxy S (Captivate) and wi-fi is giving trouble.
when i tried at a university campus, it gives error and says can't open and try again later. it is like, i get connected to the network, IP and DNS and everything is generated. But when i open browser to open a website, instead of taking me to login page it gives the above error.
here is what i get when i try to open a website.
'web page not available'. the page might be temporarily down or it may have been moved permanently to new address.
here are some suggestions:
- check to make sure device has signal and data connection. (I made sure it is connected to wifi)
- reload page later. (i tried after 5 mins, same result)
- view cached copy from google. (doesn't work either)
i am not able to understand why is this happening. i tried restarting the phone after connecting to wifi but no luck. any pointers?
Sounds like they use a portal system which requires logon and doesn't play nice with the Captivate's browser. Unfortunately many such portal systems are written poorly and I've even seen some that only work with Internet Explorer.
You could try a different browser on the Captivate. Dolphin allows spoofing assorted User Agents, which might help.
Hey guys, I have the same problem connecting to m school's network login page. It would say connected but the website always says cant be found. But the good news is that I found a way to connect to it manually! What you need is your captivate and friends iphone 4 or 3gs. First have use your friends iphone to connect to the wifi and then go into wifi settings. You should see 2 DNS address, Ip address, netmask (subnet mask) and router address. Now jot those addresses down except the ip address. Go to settings->wireless and network->Wi-Fi settings->now tap the bottom left button under the samsung logo and click advanced. Now check use static ip. Do not enter anything for your ip address just yet (we will do this last). Now enter router address into gateway, subnet mask into netmask, DNS1 to DNS1 and DNS2 to DNS2. ok when you are done click back and tap the network you want to connect to. Once you are connected jot down your ip address by taping the network once more. now go back to where the static ip was and input the ip address you just jot down into the ip address underneath use static ip. Disconnect and reconnect to the desired network. You may have to do this a few times or reboot your phone. This has been working for me so far around different buildings but with the same school network connection. I hope this helps cheers!

Yeah, my school uses the Bradford dissovable agent. Funny thing is, some connections work perfectly, others not at all. Technically none should work, and sometimes I feel that maybe I should tell them that sometimes somehow it is possible to bypass the whole agent thing- but why rock the boat just yet
Does it need a proxy to work? If so, this app is amazing.

I figured it out a month ago, and it is actually petty easy. But you really have to change ip address manually, usually just the last number.

Hello,
We have 2 sony xperia s phones at home and i placed cyanogenmod 10 on both phones but now we seem to have the same mac address. Thus, if I go on the internet with one phone, the other will get rejected (connection with the internet is lost). Only one device can use wifi at the same time. Is there anyway to resolve this problem? I read the forum and I have seen the method for temporarely change (which, btw, doesn't work for me either) of mac addresses, but since we both had a different mac adress before using CM10, there has to be a way to change it permanently I guess.
Thanks in advance. Kind regards,
Siemie
Hey guys, I have tried almost every single method to change the mac ID on my phone due to some issues with my home router, but I havent been able to succeed at all with any of the mac changing apps and methods. Please do help.

Have you tried the terminal emulator method? It will moreso spoof your mac address as your actual mac address is hard coded.
