MAC Caching?

does anyone know if there is something on the phone that caches MAC addresses (other than just an ARP table).
At my work we recently changed out a router but gave it the same name it used to have. We used to broadcast the SSID but are no longer doing so so I had to "add" a network. I put in the SSID and try to connect but what I'm seeing in the log is not the MAC address of the actual device so I'm not sure where it's getting it from.
e.g: Device address: 00:A2:F0:A3:00:F1
What I see in the logs:
Code:
V/WifiMonitor( 1400): Event [CTRL-EVENT-STATE-CHANGE id=-1 state=2]
V/WifiStateTracker( 1400): Changing supplicant state: DISCONNECTED ==> SCANNING
V/WifiMonitor( 1400): Event [Trying to associate with 02:5c:71:ee:ac:1c (SSID='MYSSID' freq=2417 MHz)]
V/WifiMonitor( 1400): Event [CTRL-EVENT-STATE-CHANGE id=-1 state=3]
V/WifiStateTracker( 1400): Changing supplicant state: SCANNING ==> ASSOCIATING
D/WifiStateTracker( 1400): Deconfiguring interface and stopping DHCP
D/SettingsWifiEnabler( 2956): Received network state changed to NetworkInfo: type: WIFI[], state: DISCONNECTED/DISCONNECTED, reason: (unspecified), extra: (none), roaming: false, failover: false, isAvailable: true
V/WifiMonitor( 1400): Event [Authentication with 02:5c:71:ee:ac:1c timed out.]
I've looked on other devices that have successfully connected to verify the new target MAC but it looks like my phone might have a MAC association with the SSID _saved_ somewhere?
I've tried forgetting the network and re-adding it as well as rebooting the phone etc. Any ideas? is there a db somewhere that might store this info?

I've upgraded my ROM and everything works now

Wlan suddenly stopped working.

Hi.
Ive been using cyanogenmod since i got my nexus.
Been running gr8. No problems what so ever.
Now however my wlan suddenly decided to be unavailable.
I was running CM5.0.6 + DesireCamera OC/UV kernel.
Symptoms: When enabling Wifi i get no Icon and if i scan for networks I see no networks.
What ive tried so far without luck in order.
Reflash cm 5.0.6. <- multiple times
reflash desirecam <- multiple times
push bcm4329.ko <- multiple times
wiped all and
Kang-o-rama 0.6
Edit
Just tried reflashing radio and then pushing bcm4329.ko.
still no go
And it still isnt working
Am i missing something ?
Heres what i got from lolcat.
V/WifiStateTracker( 134): Connection to supplicant established, state=SCANNING
D/NetworkStateTracker( 134): setDetailed state, old =DISCONNECTED and new state=SCANNING
V/WifiStateTracker( 134): Changing supplicant state: SCANNING ==> SCANNING

thanks in advance for any help.

[Q] IP address bouncing

Rooted but stock Galaxy. When I turn WiFi on at home the Galaxy keeps dropping the IP and requesting another as seen here in my router log:

Has anybody seen anything like this before? The WiFi icon will appear on the notification bar at top for a few seconds and then drop off again, only to reappear in few seconds later. I have deleted the connection and restablished, rebooted many times including the router. If I reboot the router then the two devices are happy again until the Galaxy goes back to sleep (screen goes off) and the connection is dropped. I'm using Tomato firmware on an Asus RT-N16 router and the problem could very well be with the router but I'm only seeing this issue with the Galaxy, no other devices on the network are having problems.

I had this problem with a belkin router switched to a netgear and have not had a problem since.
Now I don't know which piece of equip was causing the problem, either the cappi or the router, but I do know some wifi devices just work better together than others.
I guess don't know if my post will give any info that will help you track down the root of your problem - just if saying if you have the opportunity to test or try with other routers you should.

Solved
For the record, the problem ended up being with a program loaded on the Android called "Android Desktop Remote". Once I un-installed that application the problems with DHCP went away.
[edit] ... or so I thought. The problem did go away immediately, after fighting with the phone for an hour+, removing that problem cured it. Even through the early part of today it worked. Then all of a sudden it stopped working again and we're back to the Captivate not liking the DHCP's response, not getting an IP. Installing my old router shortly to see if anything changes.
If you look at the IP values using one of the many programs I can see that the default gateway and DSN settings are correct, but the IP address is blank or all zeros. This is very strange!

[DEV] Solve VPN PPTP connection Problems. Kernel developers please help!

I'm trying to connect to our companies network through a VPN PPTP connection. The connection does not work and this is what I can see with logcat:
Code:
D/VpnService(26589): VPN UP: down
I/SProxy_mtpd(26589): Start VPN daemon: mtpd
D/SProxy_mtpd(26589): mtpd is running after 0 msec
D/SProxy_mtpd(26589): service not yet listen()ing; try again
D/mtpd (26960): Waiting for control socket
D/mtpd (26960): Received 20 arguments
I/mtpd (26960): Using protocol pptp
I/mtpd (26960): Connecting to xxx.xxx.xxx.xxx port 1723
I/SProxy_mtpd(26589): got data from control socket: 20
I/mtpd (26960): Connection established (socket = 12)
D/mtpd (26960): Sending SCCRQ
D/mtpd (26960): Received SCCRP -> Sending OCRQ (local = 50624)
I/mtpd (26960): Tunnel established
D/mtpd (26960): Received OCRQ (remote = 0)
I/mtpd (26960): Session established
I/mtpd (26960): Creating PPPoX socket
F/mtpd (26960): Socket() Address family not supported by protocol
So as you can see the tunnel works but the problem is with the socket() call returning an error.
The problem is here in pptp.c line 238 I think.
Can any kernel developer help? Perhaps this is only a kernel configuration issue because standard HTC Desire and Motorola Droid seem to work without problem.
I have tested it on the P500 with stock kernel, drellisdee kernel and Der_Caveman kernel. Always the same problem.

Have you tried OpenVPN from Market?
You'll need root and busybox.

OpenVPN does not use PPTP. This will not work in my case.

You should try ROM Prime!
I have the same problem like you. Only Prime Rom can solve this, I think the problem is the version, Prime uses 2.2.1, others use 2.2!

Hmm, 2.2.1 uses a different kernel. Perhaps we have to check kernel configs of both versions.

VPN problems

I have some problems using VPN on Gingerbread.
I upgraded my I9000 to a stock JVO with CF root. Now I noticed that I can no longer connect successfully to my VPN server. Before I was using I9000XXJPY and was working, but now it starts to connect and just stay with "Connecting..." for about 1min then drops.
Because I have access on the VPN server I can see the auth going ok and the VPN tunnel going up. I can even ping for couple of sec the VPN IP.
Here is the related server log:

Is there any way I could debug the pptp connection on the android? Anyone have VPN working on Gingerbread JVO or other versions? Any ideas what I could try?

Nobody using VPN in Gingerbread? Any feedback would be appreciated.

rising the stakes
Ok, since nobody rush here, I will raise the stakes:
Who can help me to find a fix for this problem will win a 3 month VPN account to a VPN provider of my choice (lots of servers to use there).
If anyone have a android setup close to mine and it's VPN works, let me know.

Have u tried any other kernel or turning VPN encryption off. Also try 1Vpn app from the market
Sent from my GT-I9000 using XDA Premium App

Did you turn encryption OFF (uncheck) on your phone?
AFAIK, there is no mppe encryption support in the stock android firmware. Maybe your previous firmware included the module? Anyway, PPTP works fine for me with MPPE disabled, but not if I require it. Hope this helps...

I do get the same behavior with or without the mppe enabled. It doesn't looks like to be a encryption problem as I can see the log in successful on the server and even can ping the client IP after for couple of seconds. It looks like the VpnService does not see the connection being established and it just stops it after couple of seconds.

Never got VPN working successfully even in 2.2 and 2.2.1. It was able to connect to the VPN service (can't remember if I used PPTP or L2TP) but I was unable to browse any website or connect to anything on the internet.
I was told on some forum there's some bug in Android causing this. Anyways, doesn't sound identical to the issue you had but I thought I'd mention this.

Worked for me when using 2.2.1 JPY, both PPTP and L2TP. I suspect it's a VpnService problem rather then a pptp problem, so if anyone on 2.3.3 JVO or similar have VPN running ok, would appreciate if would send me on PM or attached here the VpnService.apk and .odex he run.

isn't it the same problem as posted on the android google code site:
http://code.google.com/p/android/issues/detail?id=4706

appears to still not be working in jvp.. no one seems to have it working with 3g on any phone with gingerbread.. it appears to work ok over wifi.. i also need i working in 3g in gb. .so i am staying on froyo for now.
