[Q] Failed Ping ipaddr - Samsung Galaxy Nexus

Under phone settings I keep getting ping ipaddr - fail, ping hostname - pass, HTTP client - pass. I still have internet and all seems to be working fine. I had a random MMS not send which led me to check my settings. Not sure why it keeps saying unreachable. The thing I've recently done was flash miui. I wiped then went back to mmuzzy's 4.2.2 ROM, I have the newest radio available. Anyone else experience this?

Unreachable could be your wifi router causing the problem. Try reboot the Router and see if it corrects itself.

Even if it occurs while I'm on mobile data?

Data seems to be working otherwise.

Wifi problem with updated ROM

Hi,
I'm having problems with the latest LVSW ROM. The Wifi doesn't work on my 8525 anymore.
I got an error message and I only got it once while trying to connect to my Wifi at home and I wish I wrote it down. It complained of a DHCP error, something related to Pocket PC.
That's something I noticed as well when I Active Sync to my PC. It recognized it as a Pocket PC device.
Has anyone encountered this error? I've soft reset and hard reset my unit and it just won't connect via Wifi. It would try to Connect, then comes with a
Cannot connect to the network. Check your network and service provider settings and try again.
I hope someone can help.
Now I'm getting a
Cannot obtain a server assigned IP address. Try again later or enter an IP address in Network settings.
Thank you very much in advance.

I am also having this problem, has anyone found a solution?
Thanks.

WiFi is broken after rooting

After I rooted, my phone won't connect to WiFi anymore.
I started with the Cyanogen Mod (6.0.2). When I try to connect to a WiFi network, it tries to connect and gets to the "obtaining ip address" message, and finally fails to connect.
I figured I should try a different mod and completely wipe the card. So, I did this via Rom Manager. I had it backup and wipe, then install Skyraider w/ Sense. The same problem persists.
Does anyone have any ideas how I can troubleshoot this problem? Thanks!
Dumb question, but you did re-select the WiFi network you want to connect to, and re-entered the password for that network (if one is required)?

Yeah I have. I've tested this with multiple WiFi networks on each mod. It always gets to the point of "obtaining ip address" which to my understanding means the password has worked. Either way, I'll always long press to forget the password, and re-connect. Even disabling the password on the router still causes the same issue.

[Q] wifi adhoc "obtaining ip address"

Hi friends
Searched the forum and tried the proposed solutions but nothing helped.
I'm trying connect to addhoc wifi on my desire HD os=2.2
I replaced the wpa_supplicant file with one of those that exists on the forum and
indeed now i see adhoc networks but the connection is not stable - it goes like connecting -> obtaining ip address -> connected -> disconnected
and so on in loop ... i verified that the ip is static and i even put gateway+mask+dns.
when trying to ping the target it even sometimes succeeds!
Tried with several different adhoc targets and tried both wpa_supplicant for ver 0.5 & ver 0.6
Please does someone can help ?
thanks

My phone is samsung galaxy GT - I 5503. I do too and obtainging IP address...
This question not yet solved
I have the same issue with my sgs2. I get no connection ever, only a constant "Obtaining IP address.."
I'd suggest resetting your router and forgetting the network and trying to reconnect. Also a static IP might work but as for finding any of your provider's info, that's up to you. Unfortunately, XDA doesn't even recognize my network (Sasktel) so I am having a very tough time with this!
most probably firewall problem , i had same problem with hotspot doing exactly as you discribe.
it can also happen by some custom Roms and don't happen with others ( firewall disabled ) .
Also lot of sense Roms have an issue with that exact wifi problem , not like AOSP Roms ,i don't know why
I only had this problem with a network called; 'eduroam', my schools' network. I solved it by recotting & changing the network security TLS/TTLS/EAP or somethinf like that.

No wifi on gedrom.

There is no wifi on gederom or any CM9 rom.I turn on and off wifi and still it doesn't work. I have an Intellinet router.
Thanks for any replies.
You should probably try changing your router's channel. I've heard that channel 13 is bad news ... and I think that was for a cm9 rom. Anyway, it's definitely worth a shot.
Are you wiping cache/dalvik before flashing new roms? If you're going from one developers rom to another developer, you should do a factory reset, then wipe, then install rom. If all you're doing to flashing roms from the same developer, then a cache/dalvik wipe is all you need to do. Hope that helps!
Wipe that kindle clean. Are you using fios? I've heard of a few people having issues with them.
I notice I can't see one particular Linksys wireless router at one of my job sites, but since we have two wireless routers it doesn't really affect me. No idea why...but maybe there is something someone else knows that can help understand the issue?
I still have no wifi and I wiped my kindle fire clean too. I changed the wifi channel from 11 to 4 but still it doesn't work.The connection shows up and when I enter the password the signal strength goes down.It says Authenticating and then it says saved and doesn't connect.
Any Help please.

Can you go someplace where there is another router? Like I said, I notice there is one particular flavor of Linksys router that my Fire can't see on this ROM, yet at home I have a different model Linksys and there is no problem. Check it out on another router to see if it's just some weird compatibility issue.

Check the router and see if QOS is enabled. If so try turning it off.
I don't have any other routers in my house. With static I still get the same result.
Any way thanks for all the replies.

IF FOR SOME REASON WIFI DOESN'T WORK ON THE FIRST BOOTUP DO THE FOLLOWING:
This is what hashcode say's
Enter Terminal Emulator
Type: su
Type: fix-mac.sh
Exit Terminal Emulator
Reboot

Is there a reason you can't go to a coffee shop, library, or any number of other hotspots with your Fire? I mean if you have a medical issue that keeps you bedridden, I understand, but if not, there are usually routers everywhere you can try connecting to.
Please try connecting to your wifi and then pastebin the output from the following and PM me the links:
Adb shell "dmesg" > dmesg.txt
Adb logcat > logcat.txt
Thanks

The fix-mac.sh fix still doesn't work and I found something with build.prop and settings.db and with some locale things while I was with channel 11 and still it didn't work.
Thanks for the replies.
Daniel120201: I looked at your pastebin logs and here are some notes:
The key lines in your logs are:
logcat: 7551.D/wpa_supplicant( 1040): EAPOL: Supplicant port status: Unauthorized
dmesg: 3949.<7>[ 538.654174] wlan0: disassociated from 00:0e:e8:d5:c5:d1 (Reason: 15)
When I looked up "Reason 15" as a disassociation error, I find:
Reason code 15: 4-Way Handshake timeout.
When I looked up how 4-Way Handshake works:
http://en.wikipedia.org/wiki/IEEE_802.11i-2004
On that page it references CCMP protocol for WPA2 and IPSEC:
http://en.wikipedia.org/wiki/CCMP
And on that page it mentions this:
CCMP is an enhanced data cryptographic encapsulation mechanism designed for data confidentiality and based upon the Counter Mode with CBC-MAC (CCM) of the AES standard
I double-checked the kernel config and low and behold:
#
# Authenticated Encryption with Associated Data
#
# CONFIG_CRYPTO_CCM is not set
I think this can be solved via a kernel config change. Later today, I will create a new kernel only .zip file with this change and I'd like for you to test it.
This also may solve IPSEC issues as well.
Here is a link to the new kernel w/ CCMP support added [Kernel #12 06/08]:

Thanks for the kernel Hashcode.It's Works.
You're quite welcome. I think there were a few others who were in the same boat.
Updated kernel Still same problem for me

[Q] Help ? Xperia ARC+DarkKernel+LX : Wifi almost working, only sees the gateway

Hi,
This is my first post, on this great forum, so I'm posting as a "noob"...
So my problem :
- I installed the LegacyXperia 20130908 CM10.1 release. It was working almost OK
- But because of the high wifi drain, I gave the lated DarkKernel a try (http://forum.xda-developers.com/showthread.php?t=2451839)
It seems to perform very good BUT I just noticed something really weird : I have access to the internet through my wifi LAN, I can ping my gateway BUT nothing else works on the local LAN :
ping fails :
[email protected]:/ $ ping -c 1 192.168.1.13
PING 192.168.1.13 (192.168.1.13) 56(84) bytes of data.
From 192.168.1.10 icmp_seq=1 Destination Host Unreachable
The arp table seems incomplete :
1|[email protected]:/ $ arp -a
d810.home (192.168.1.13) at <incomplete> on wlan0
livebox.home (192.168.1.1) at 00:1f:95:26:25:4d [ether] on wlan0
The routes seem ok, the ip neighbours are not :
[email protected]:/ $ ip route show
default via 192.168.1.1 dev wlan0
192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.10
192.168.1.1 dev wlan0 scope link
[email protected]:/ $ ip neighbor show
192.168.1.13 dev wlan0 FAILED
192.168.1.1 dev wlan0 lladdr 00:1f:95:26:25:4d STALE
AH, on more weird thing, the kernel arp table has lots of zeroes for the unreachable devices MAC adresses (yes, I have 192.168.1.13 and 1.15 are up and running) :
[email protected]:/ $ cat /proc/net/arp
IP address HW type Flags HW address Mask Device
192.168.1.1 0x1 0x2 00:1f:95:26:25:4d * wlan0
192.168.1.15 0x1 0x0 00:00:00:00:00:00 * wlan0
And I can't seem to be able to communicate with the local LAN only with the android phone...
I have static IPs in my DSL router, I can't set the arp tables manually.
I *think* this was all working with the default ROM kernel, but before I attempt to revert back to that kernel to check (I backed up the modules, but yet another noob thing, I'm not sure putting back the tar into /lib/modules will be enough...) :
==> this is my noob question : anybody knows how I can report that to the dev, and how I can get help ?
Since it's my first post (only 9 remaining now !), I can't post in dev section...
Thanks && regards
Did you flash the DarkModules?
Hi,
Yes i did flash them in cwm...

Hi,
Thanks for the reminder.
But actually, by dev, i meant the kernel dev : the issue i see is not a force close or things like that,
and it appeared after i flashed this new kernel which seems better for the battery.
I think this is a kernel/wifi modules issue, not a rom one.
Or a noob error, but then i hope some of you can help me understand my error
As i said, wifi is somehow working since i'm replying just now using it...
It's just that apart from the dhcp/gateway, my device seems unable to learn any mac address with this kernel.
I haven't tried a tcpdump for now, and i wanted to test ipv6 but my 'great' dsl/wifi box does not support v6 - yes, that still exists...
Regards

He is also developing the kernel together with his team, which is given within the .zip file.
Ahh... txs.
OK, now I don't understand anymore anything...
I did :
- remount rw /system/
- cleanup and then restore the /system/lib/modules backup I had done - using tar
- reflash the ROM kernel (200130908)
And... still no ping on the wLAN, but I can ping google and the GW. ??
The arp table still shows me incomplete records.
Still I'm 100% sure I could connect before : I did use connectbot to ssh onto my computer and setup new ssh keys.
I don't know what else I can try exept reboot the dsl box (which is the wifi router)... or delete the recorded stuff in that dsl box and that reference my arc s.
Or reflash all, but I always manage loosing stuff when I reflash (which I avoïd doing then), even with titanium backup
That's all really weird...
Side question : is there *always* a captcha verification on every post ?
Cheers

Which DNS server are you using? Did you change anything else by WiFi?
The captcha is only for limited amount of posts, then it will disappear.
I did not change any dns setting, but i saw local names in the terminal, so i must be using my dhcp/box dns.
You remind me i unchecked the wifi optomizations with the new kernel: i read this was causing arp issues on nexus devices...
Lets try to re-enable that... appart from this, i changed nothing after i flashed this kernel.
Except I tried 1.8ghz (it worked well), but this disappeared sincei restored the official rom krtnel
Thats really all i changed since i tried the new kernel yesterday evening
Can you believe this...
- Restoring the wifi optimisations did not help
- rebooting the DSL box helped. For 5 minutes.
I was able to ping a computer on the network, but not to go to the dsl box webserver. and I lost internet.
- subsequent dsl box reboots did not solve anything : no internet, no webserver, no connexion even on the wired PCs , powerd them on or off, nothing.
- *unplugging* everything + dsl box reboot => did restore internet+wifi on the arc
- replugging the PCs did not break
- and I can now see/ping the LAN with the arc s
Only remains, now, the dlink switch I have downtstairs that is the only stuff that remained plugged all time (theres a device on it, but it's off)..... It must have switched to a "netkill" state somehow. Funny, isn't it ?
let's now start wireshark, reinstall the new kernel, and see if there is any difference... and lastly reboot/replug the dlink switch
the come back for the (arp) ping of death ?
Regards
Last experiments:
- fired wireshark, to capture any network suspicious paquets
- reflashed the new kernel+modules
- retried ping / local LAN
Still working.
I rebooted my last network device (dlink switch), repluggued it : everything is still working.
conclusion : I don't understand :laugh:
Cheers
