At work we have wifi, but it's limited to the MAC addresses of the laptops that have been handed out. Is there any way to spoof the mac address on my phone to match that of my laptop (which would be switched off at the time) ?
Thanks,
I haven't heard of any way to do that for pocketpcs. Why don't you use smac on your laptop and change the laptop's mac to your current pda's mac adress? And you need administrative rights or an admin that will to let you do this / change your laptop's mac in the system database or whatever.
No go on that I'm afraid. It's my IT department that controls the issuance of laptops and the same people that lock down the wifi access by mac address. They'd notice a mac address that doesn't belong because we only use Thinkpads.
Well I was interested in that too but when I didn't need it anymore I stopped searching. If you search a lot you might find a working solution, take a look there if you have a ee-subscription (I don't) http://www.experts-exchange.com/Networking/Microsoft_Network/Q_21206803.html
or take a look at the netstumbler forum or the efnet channel. I will do a little research too. I think the mac adress can probably be changed through the registry settings, some cards support that.
....not with a pre-made tool or simple reg.tweak AFAIK
there were some old threads somewhere here on xda about it,
Now, I don't remember the details, but I'm pretty sure someone managed it, but only with some badass coding, instructions for which were way above my head. Check the old threads in networking sub-forum...
I have 2 old PIX firewalls I can use, or I could could use OpenVPN inside WRT, or anything. I have nothing setup yet.
What's the easiest VPN for the EVO to hook to?
I'm running unrooted 2.2.
There is no PIX or OpenVPN support in Android. If you root and download "VPN Connections" you can connect to a PIX or OpenVPN server. I have connected to each. Make sure to read through the bug reports. The version I was using had a routing problem that had to be corrected in vpnc-script.
I've managed to get my evo to connect a winxp pro box set up as a pptp vpn server. but only if I disable encryption on the evo. which kind of defeats the purpose.
Basically, android VPN support is spotty at best. There is an epically long google code thread on the subject.
For the time being setting up an ssh server and using connectbot seems to the best way to securely access remote networks. It's far from perfect but it's the best solution I've seen.
Some people have reported vpn success using custom roms. But they are the exception. And setting up an ssh server is probably easier than tweaking a custom rom, IMHO.
This conversation is over my head, but Logmein Ignition owns my soul.
Thanks everyone.
I might have to root my EVO again(last one was rooted, but had to get a new EVO through warantee)
Just updated my HD7 to the update with internet sharing. After this, I can confirm that every time I reboot my phone, I get a new mac address. Which prevents me from connecting to my MAC-address-filtered wifi. I've done it 6 times and gotten 6 unique MAC addresses.
Does this happen to anyone else's phone? HD7 specific? or all phones with internet sharing? My internet sharing is turned off.
That's strange, I've never heard of a device with a dynamic MAC address before. Does your phone have one printed under the battery?
Nope, just IMEI, SN and PN. No MAC address.
This must be related in internet sharing somehow.

I can confirm this on my HD7.
MAC changes on every reboot.
I confirm too,i have the issue of mac adress changing every reboot
& my wifi is not visible since the update,My wifi is N and i can only see wifi G near me but not mine
hi
for me too : mac adress change after shutdown.
for time don't shutdown the phone to have same mac adress with my internet box.
htc support tell me that they will answer on monday.
but i think it's a big problem with this update...
Ben
That's a bit strange. Normally you can't change MAC's for yourself, only spoofing is possible. If WP is really changing the MAC adress with every reboot, WP needs a valid MAC adress block licensed from IEEE, otherwise it would be a violation against IEEE.
I thought mac address we're never aloud to change!?
Lol that's illegal as all hell, a dynamic mac address
Gotta be a glitch in the firmware surely? No way that's allowed. Your definitely sure it's not a dynamic IP address you're seeing?

ive also asked this question a couple of days ago right after applying the htc internet sharing update. and ive posted my question here (entry #38) and people provided good answers about it. hope this helps
Yes, mine also changes it's only when i read this thread and test my hd7 and i notice the changes.But I S is a breeze.
The issue is that some people assign static IPs to devices on their home networks, and this is done in most routers via MAC address coupling (MAC a always gets IP z and so forth). That way you can simply block all devices you and people in the residence do not own. I do it on all my machines for development reasons, cause I like knowing I can always use x IP address to get at a certain machine even if I turn it off or it's down for a while for repairs. The IP never changes as long as I continue to use that specific network card in the computer.
I don't know why they would do that. Perhaps for security reasons?
I have the same problem - cannot connect to my University WiFi network as the MAC address keeps on changing....
This is crazy!
They better get on that quick! They could get in a lot of **** for that
putting aside the weird WP7 behaviour for the moment...
MAC filtering is useless as a security measure. It's trivially spoofable by anyone who actually wants to attack your network, and causes a pain in the arse for yourself. do yourself a favour and disable it already. the only thing it might be good for is router-side internet access control of your technically challenged 8 year old who doesn't know how to use google.
just use a strong password i.e. 20+ characters alpha (upper & lower) + numeric + special characters, and proper wireless security (WPA-2 AES, or at least WPA AES) and you'll be just fine.
Confirming
That update was a bag full of $$$$ !Luckly I was able to restore through Zune,but my Bootloader (SPL) was also updated to 5.01 and no way of going back!
With regards to the missing WiFi network - make sure it's not using Channel 13. The new update seems to disable the use of Channel 13 for some reason.
There is also another issue with the changing MAC's - I believe that some "public" WiFi networks such as the cloud use the MAC to remember your device and allow it to connect...

Mac filtering is not useless as a security measure. It's not used by itself. It's used in conjunction with other methods, the same way businesses also hide their wireless network's SSID.
I'm not filtering on an Open Connection. That would be retarded.
Seriously...

im not sure though but im guessing so does other apps with secured log in parameters. i do have the bank of america app. right after i did the update, and after inluding the new mac to my networks allowed list of mac addresses, the boa app again posted a message saying that the device where im accessing boa has not been used previously to access the account. so im guessing that it saves all the mac addresses of devices that accessed a boa account.
Hey fellow GN users!
I seem to be having a problem with my wifi mac address changing every time I reboot... I was wondering if this is a hardware or a software problem? I have mac address filtering set on my router so it would be convenient if the mac address didn't change... I'm still on my first week with the phone and I want to make sure everything works before my 14 day period is over. Is anyone else having this problem? Anyone know a fix if they are having the problem? Any help would be most appreciated! Thanks!

Welcome to the club!

From my support call to Samsung, this is apparently a software issue, but I'm not sure I believe that 100%. For me, I switched my home wifi around to use WPA-2 with a ridiculously long password and no MAC filter to make me no longer care, but that's just me I'm secretly hoping to be the guy that can tell Google "hey - you fixed it!!", probably why I don't push harder to exchange my phone.
Please add a comment/star to my Google Code issue if you don't mind; the more people that chime in the better off we will be. I truly believe that a lot of GNs have this problem since it's not something that most people would notice.
If getting rid of your MAC filter is impossible, you should really consider exchanging your device, I imagine it will be quite a while (if ever) for this to get fixed. Call me a pessimist if you must.
Odd, isn't a MAC address suppose to be hard flashed to the radio?
Mine started changing the Mac address today after rooting. The last month with it running stock, no issue. Hmmm, used the Galaxy Nexus tool kit for rooting.
MAC address filtering is not really a good security measure. It is very easy for someone to see the MAC addresses connected to a particular WAP and clone one of them.
You are much more secure using WPA2 with a decently long password.
I just started experiencing the problem yesterday. My phone DID have a 2c:44 address and I switched roms pretty frequently. I flashed an update to the Codename rom that I had been using for a while, and I wasn't able to connect to my router. Knowing what I thought I knew about MAC addresses I didnt think about it, i rebooted all sortsa crap, then thought what the hell check the mac filter list, and sure enough mine had changed, and now i'm sporting one of the dreaded 00:90:4c addresses and the last few characters change every reboot... I am not a happy camper.
I understand how it isn't an amazing security option, but in a small apartment building in the sticks in PA I know my neighbors have no idea how to get around it. WPA2 uses up too much bandwidth overhead for streaming 1080p over wifi. That's why I dont use it and use MAC filtering.

It is not a bandwidth overhead but a resource hog. But I get your jist. I save all my HD streaming for wired.
Have you done an EFS partition backup?
Sent from my Galaxy Nexus using XDA App
I didnt know what and EFS partition was until I just googled it and I've been rooting / rom'ing phones and devices (5 different phones and 2 tablets) for the last 2 years and never once heard of it.. that being said i did a nandroid backup and restoring it did not help
I'm going to try Odin flashing back, I read somewhere it fixes IMEI / EFS corruption, heres hoping it works for wlan mac addresses. Only place I found an Odin image of it was from megaupload so it will take a long time to get it...
Edit: if you clicked on the link for the firmware i posted, do NOT click it, i think that was GSM
Well that was a bust, odining back didn't help... I dont want to risk swapping the phone out considering i put one of those zagg screen protectors on it for a phone that is going to have the same problem... I am concerned because of the fact that i did have a valid sticking mac address, and all of a sudden it just stopped which leads me to believe it is totally software related.

Was just about to say it. +1000. There is nothing about MAC address filtering that is secure. Anyone can spoof the MAC address, and its easy to intercept them when in range.
Use a normal security protocol and you'll be better off all around. MAC filtering is just a hassle anyways.

Thank you for your concerns however as I said before I dont need crazy security, I just had to deal with rednecks connecting to my router using torrents a couple times. Since that has happened and i enabled mac filtering I haven't had any problems (i would know because my internet bandwidth would go to crap)
Actually setting up WPA2 is more of a hassle than logging into a router, clicking on one link and typing in the mac address rather than somehow finding a way to configure my network to handle the bandwidth with WPA2, which I have tried, but even with a dual band n wireless ethernet bridge with gigabit out to a gigabit switch doesnt do the trick, disable wpa2 all of a sudden all my video stuttering woes go away.
That is at a personal level, at work I have MAC filtering not to connect as a security measure but my ip address is assigned based on it, and well it's much more complicated than at home... please if you are going to post something in this thread try to be helpful.

Again, it has nothing to do with bandwidth. It has everything to do with the devices ability to encrypt and decrypt packets at full speeds, which obviously your device cannot do. You might want to step up to something a little more powerful.
I can do 1080p streaming on a G network with WPA2 enabled. The difference between my setup and yours? I am using an enterprise grade WAP (Cisco 1242). It has no problems whatsoever doing the encryption and decryption at the full wireless speed.
And I think you mentioned you were located in Central PA, and all you had to protect from was hicks. Well, I am one of those hicks (Live in Central PA as well) and I LOVE cracking in to WAPs
I am having this issue now. any solutions?

WPA2 isn't crazy security. I wouldn't recommend anybody running anything less than WPA2 with 256 bit AES encryption. If you can't run that I recommend upgrading your hardware.
so... i just started having this issue after my battery died last night now today I have a different MAC..
This has to be fixed at kernel level or maybe a script to set the mac at bootup time can be used. really annoying and stupid
First of all, I would like to thank all the developers on the site for some outstanding work. I have been trying out some of the great ROM's found here and I would just like to thank all you guys for all the hard work put into your Rom's. I am really appreciative of all the great information found here.
I have an issue I have been working on for a bit, and I was wondering if I can get some of you to comment or try to figure this one out.
At my office, we have a RV-120w Cisco firewall/router. We have a small office, and this unit has worked great in securing my server, but allowing some of my Project Manager's to remote in via IPsec. The remote VPN works great from desktop to router. We connect to the router, and then RD to the workstation.
The issue I have, is I cannot get an Android device to connect via IPsec. I can see the unit talking to the router (from the log), but the connection times out stating "Could not find a configuration".
I have tried the Cisco boards and have gotten no where. If any of you have an idea I could try, I would greatly appreacite it.
Hey,
are you making sure everything is registered right on both sides? & it might be a rom glitch to. Try flashing a differnt rom making sure you have all the right info and try again. and If that doesnt do it Idk man Im sorry :/
Stevo
L2PT only with IPsec is supported.
So you should be running IPsec and L2PT with the VPN. Probably should look into the OpenVPN installers for the android phones (i can help with that).
But my experience is that our android phones are finicky with the protocols you use.
Cisco again........
I regualrly visit forums and blogs for some VPN news, what i see the most are people having issues with vpn settings in general and specially cisco, cisco vpn routers have been rocket science to learn and use efficiently,
