[Question/Request] DHCP IP assignment timeout

Hey coders,
I have a question regarding the networking subsystem in Android.
I know that dhclient.conf in linux will allow a "timeout" parameter that lets you set the DHCP request timeout. I'm wondering if there's some way to do that in Android. It's not immediately obvious to me, so that's why I'm asking.
Before, when I was stock, my phone had no issues connecting to my work's wireless SSID--even though it would sometimes take a long time to obtain an IP address, it would eventually connect.
Now, I've flashed CyanogenMod 5.0.5.3-N1, and I can still associate with my work's wireless network, but it appears to timeout the attempt to obtain an IP address too soon. My Palm Pre and my laptop can connect to the same, and I've verified that my stock ROM can also still connect, but when I flash to CM, I can no longer obtain an IP address successfully anymore.
I'm wondering how difficult it would be to modify the DHCP obtain IP timeout?
Thanks everyone!

same problem here as well also on cm5.0.3.1 and 5.0.6.test2...

Haven't tried modifying it, but you can look at /system/etc/dhcpcd/dhcpcd.conf. Here's a man page.

Doesn't seem to help. I added "timeout 360" to the bottom of dhcpcd.conf and it doesn't increase the time that passes between "obtaining IP Address from <SSID>" and "unsuccessful".
Must be something else in android?

hi everyone,i bought HD7 last night and i have a problem with wifi.i want to connect my HD7 to my wireless routher. i must to set my HD7 IP.i can see HD7 IP but i cant change it.how can i do it? thanks

There is currently no way to set a Static IP address in Windows Phone 7, you'll have to wait for an update to come out that allows this.

You shouldn't need to manually configure your IP for the phone, the router will most likely assign your phone one if your DHCP is enabled (default on most routers). If you are wanting to connect it to your current home network and you have a wireless router, first you will need to go into the router configuration and set it to broadcast your SSID (if not already enabled). At this time the HD7 cannot connect to hidden networks (I don't see a point in hiding your SSID anyway, use better encryption, and a strong password with numbers, letters[upper and lower case], and symbols[if supported]). You can then use you HD7 to connect to your home network, once connected to your network go back into the router and look at your network. It should list all the devices currently connected to the network along with their currently assigned IP addresses. If you really need to, now that you know what IP address your router has assigned to your phone you can set your router to give your phone a static IP but really as long as you leave the router broadcasting the SSID your phone should have no problem connecting to the WiFi it should save the key and SSID, and it will get a new IP at regular intervals.

[Q] wifi adhoc issues

hi guys,
i have been breaking my head to sort this out.
i'm not able to connect to my laptop internet via wifi on the Note. i have this application called connectify that automatically creates a wifi hotspot on my laptop (i don't have a router). with this im easily able to connect symbian devices on it (my old phones)
but the Note doesn't even detect this hotspot. so i researched a lot and finally found a galaxy sii modified file "wpa_supplicant" which i replaced in the system/bin folder of my GNote. now the phone detects the hotspot but remains stuck at "Obtaining IP address". the status doesnt change from this and not able to connect.
so again i played around and enabled static IP on the phone. i entered some ip address, gateway, netmask and DNS values i got on the net (for another internet connection bsnl 3g). (my own ip is not static, im trying to share a mts mblaze datacard connection) now im getting the "connected" status but when i go to browser it doesnt load up any website. please help. hope i am clear
in ipconfig my values show as follows
ipv4 address: 180.215.40.199
subnet mask: 255.255.255.255
default gateway: 0.0.0.0
i tried with the above values and its not even reaching the "obtaining ip address" status.

Sorry...had a question, but just figured it out myself...can't help you either though.
Regards,
ChaosDM

I had the same problem before, what I did is to use a different wpa_supplicant then copying it to /system/bin, changing its permission (just copy the original wpa's permission) and rebooting afterwards.
It worked for me in stock LA4 Firmware (2.3.6). But most of the time i had to set the wifi setting to static ip so that it will connect instantly so I recommend you do the same if it doesnt connect automatically.

sorry to bring this old thread up,
but since the ICS update it seems that the wpa_supplicant replacement no longer worked ,,,after replacemant you wont be able to even turn the wifi on
wondering if there's any other way or could someone plz modify the wpa_supplicant file from the new ICS rom so to creat a new wpa_supplicant that works on ICS?
thanks!

after the latest update of Connectify, my note can connect to the hotspot by connectify without any problems

Yes indeed

[Q] issue with darkrom 3.4

Hello
since installing 3.4 I have had issues with this rom however none so serious I jumped ship however I have problems with conecting to my home wifi which is causing pain...
I have set up wifi on my note as dhcp and my netgear router is also set to give ip address via dhcp however the note will only connect sometimes otherwise the message 'obtaing ip address' is shown then the connection drops to remembered and then Im back on 3G. I have tried various fixes including re-flashing the rom providing a static ip address. I have this issue with any dhcp network the note just will not connect all the time...

It happen even on stock to me mate.What I do is turn off wifi,go to browser and navigate to any site(yeah with wifi turned off still and data network off),when it gives you error turn on wifi and refresh the page.
I know its irritating but I have no solution and it works for me

still trying to find a solution to this. setting wifi sleep policy to Never seems to help I also deleted the dhcp_list file which forces the note to reconnect from scratch each time it connects to a known network rather than selecting it from the list. still not a full fix. seems to be a samsung thing rather than rom based. do the modem downloads available control the wifi functions or are they just for radio 3g etc as I will try a different modem to see if that helps.....

Can't connect to my WiFi

Hello,
Since the last Update (global Rom) my mi9 can't connect to my WiFi, neither 2,4 GHz nor 5ghz. Has anyone else figured the same Problem or is it just me? It just says connecting and stops then.

I have the same issue but just with one router (Vodafone). Any other router connects perfect. Did factory reset on both, didn't help. Tried static ip, didn't work. I guess your router has the same problem as mine: it can't handle the changing Mac address of Android 10. Workaround for me now is to restart the phone and voila it connects.
As soon as I can get a new router I will change it.

Had the same issue. I had to put my phone ip and mac address in address reservation option in my router and now working as have to be
