[Q] HD2 doesn't show on network - HD2 Android Q&A, Help & Troubleshooting and Genera

Looking at the attached devices page on my router all my other devices (laptop, printer, other phones etc) all show up with their IP addresses but my HD2 doesn't.
It's definitely connected though as I'm able to use the internet and the WiFi control panel claims to be connected giving me an IP address. Pinging the IP address android shows me gives me a host unreachable message.
I've tried restarting everything, no change, and there isn't any devices with the same MAC address on my network either.
I'm trying to set up samba file sharing, so any help would be appreciated.
Never mind, Found a work around

This does it for me:
turn on normal Wifi
wait around 10 seconds (for Wifi to 'start')
turn on Wifi hotspot (normal wifi should turn it self off automatically)
wait around 20 seconds (the hotspot takes a while to 'start', it actually fails (error) for me, but still does the trick)
turn normal Wifi on again

XDAIIi wi-fi problem

Hi all. I looked at several wi-fi posts on here, but couldn't find anything related to my problem.
I'm beginning to suspect that it's because of something stupid I'm doing, cos it really should be working...
Anyhoo ...I have a wireless router at home, and it's serving 3 PCs with DHCP IP addresses, and an internet connection. I have no issues with it.
What I'm trying to do now is get my shiny new XDAIIi to connect, so that I can have the damn thing on the internet. So far, no luck.
Now, I have got the XDA to detect my SSID. It detects all the settings, and tells me it's connected. I even have a signal strength bar on it which reads about 50%.
However, when I set it to pick up a DHCP address it stubbornly refuses, remaining with a "I can't see a DHCP server" 169.x.x.x address.
I've tried reserving an address on the router and allocating it to the MAC address of the XDA, and manually setting the XDA to have that IP address, entering my router as the gateway, and even entering 2 valid DNS server IPs from my ISP into the name server entries. Still nothing. It says it's connected with the IP address I allocated, but I have no net connection, and I can't ping that address from any of my PCs.
All the while the status screen on the router tells me that the device, with it's MAC address, is connected to the router fine.
Surely this has to be something simple. I have set up all the clients and router for my network, and the settings on the XDA are pertty much the same, and really SHOULD be working.
I'm kinda at my wits end.
So basically any suggestions or advice, or anyone with similar experiences please get in touch, cos I'm struggling to see what I've done wrong, and it's giving me an ulcer.
Many thanks in advance.

3COM WAP (3CRWE454G72) - XDA IIi WIFI Problems
Hi Jess,
I very much share your frustration.
I have a 3COM WAP (3CRWE454G72) which has served me well. I have a few machines at home working from it. At work we have 20+ machines working from the same model (older firmware).
My specs are as follow:
3C number 3CRWE454G72
Software version 1.03.07A
Boot loader version 1.00.00
Wireless version V1.0.2.1
Hardware version R01A
Don't have the office one's specs here at the moment ...
At work I can get an IP address (there's a windows DHCP server) .. AND I can ping google and traceroute to google. BUT, XDA IIi doesn't seem "know" that it's connected (e.g. network settings shows the WAP as available, but not connected). SKYPE even works!! But nothing else, no IE, no Terminal Services Client, no Avant Go, no network ActiveSync. They all say that the is no network card configured (but with vxUTIL, vxIPCONFIG, etc). I can see ALL the IP details from the DHCP server.
At home it's worse. I can't even get it to connect to the WAP (either with WEP 128, WEP 64 or encryption turned off). As I'm not even getting an IP address at home from the WAP's DHCP server, I've built a new DHCP server on my one linux box and it works for all my machines ... now I can actually trace requests from devices for IP's ... and the XDA IIi never requests an IP address. Which tells me that it's not even getting through the first stages of connecting with the WAP (again tried WEP, NO WEP).
To make things worse. I have been able to connect to some open WAP's in the neighbourhood ... everything functioning normal.
I'm losing the will to live here also ... ;-)
Wolfie
the plot thickens...
Hi Wolfie.
Well, at this end I seem to have more news.
By removing all WEP encryption and removing the MAC address access restriction I had enabled, I got the XDAIIi online, and all was working.
I then enabled the security a step at a time, and at each step updated the configuration on the handheld, and it still all worked. I was so pleased.
)
However this morning I have come to put the thing online again, and once again it refuses to pick up a DHCP address.
I tried my process again, and this time it wont work.
It definitely seems that it's the encryption that's stopping it, but I can't get it working this morning.
When I disabled everything I managed to get it online, but then re-enabling the security killed it and I can't get it to come online again.
SIGH
Oh well, I will try again later. Fussy thing. Anyone ever manage to solve this ??
Jess
have u tried soft reseting the device and retrying, sometimes that cures these hiccups

WIFI WOES
Jess, thanks for the reply. There's hope. ;-)
I have tried your approach yesterday. However, to no avail. At home I completely opened my WAP, e.g. any MAC, no WEP/WPA, etc. But still nothing. When I look at my log files on the WAP. I can see plenty of entries coming from my XDA IIi ...
04 min(s) 41 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 43 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 45 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 46 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 48 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
04 min(s) 50 sec(s) after system power on : Wireless MAC address 00:09:2D:14:C9:F2 has connected with the device
... and it just goes on and on and on .... while trying to connect.
At the same time in all connections attemps, I don't get a single entry in my DHCP servers log saying that my XDA II attempted to connect.
Jim: I've tried hard resets, soft resets, O2 Active installed, Corporate mode, pretty much everything my single brain-cell can come up with. ;-)
The thing is definitely a little fiddly indeed ...
The search goes on ...
... anybody out there got their XDA IIi working with WIFI using DHCP and WEP or WPA?
Did you ever get this working?
I have a shiny new XDAIIi and have been trying to get connected via my Cisco Aironet 1200 WAP. The device happily detects my network, accepts the WEP key fine (complains if I enter the wrong key so I know it's communicating) but refuses to pick up an IP address. The Wireless LAN Manager just sits there "Scanning network..."
I firmly belive I'm just missing something but...........
Any help gratefully received :?

I got my QTek 2020i today and for the life of me I can't get it to connect to the internet using my wifi connection @ home
I also have a 3COM router 3CRWE754G72-A and I have my home pc connected to this and also occassionally my work PC - both with no probs.
I can get the qtek to connect and I get a 50% signal strength and I can view an IP address and everything looks good but I can't seem to setup a "Connection" as required by IE?
This is what I get:
"Cannot connect with current connection settings. To change your connection settings, tap Settins"
I tap settings and I get this:
My ISP
Add a new modem connection
My ISP
Add a new modem connection
Add a new VPN server connection
Set up my proxy server
I've gone into each of these and had a "play" but I still can't get the bloody thing to work :evil:
Can someone PLEASE help as this is starting to drive me mad! - I'm not giving up easily...I've been trying to get this to work for a good 4 hours now and I can't find anything in the manual or on the web that helps...this post was the closest I could fine >>> hence the bump!

have you try to configure the network cards in the connection setting and set the internet using the tiacxwln Compatible Wireless Ethernet?

Okay, I can get the connection to read "connected" via the Wireless Lan Manager and I can get an IP address - which is totally different to all the other PC's that use my wifi connection - they're all 192.168.1.x whereas this is very different? - the address that I get isn't even the same as the IP Address of my router - I have a static IP address so I know this isn't changing???
Also, when I view the network card page I see the following:
Configure Wireless Networks
Add New...
3Com Available
I can click on this and view the settings for it or I can hold-click and get the option of connecting. If I do this, it just says "connecting"; it never actually says "connected"?
Anyone know where I can get a walkthrough for this?

3 Com Routers
Hi, DotN
I put a 3Com router in my local pub.
I have no problem connecting to it and solving the usual pub talk problems with it.
If you are getting a connection but your IP address starts with 169.254 then I would say you have a WEP problem. The software only appears to check for incorrectly formatted WEP keys, so either turn it off or make sure you enter the correct key. When selecting connect to a router the message sticks on connecting, come out of the screen and go back in after about 30 secs. Check you ip address. I have had some issues with GRPS trying to connect, but they seem to go away after a couple of hides.
I have to say that I am not over the moon with my XDA2i, but the wifi part has worked pretty well for me.

Hi Paddy
Thanks for the info. You're bang on with the IP Address!...169.254.x.x
So what encryption can I use?
I've deffinately got the correct password but it's obviously not working
Cheers
Wayne
Hi again
Okay, I've just checked the encryption and I'm using WPA-PSK authentication with TKIP encryption.
Is this what you had?
Cheers

Are you using a password or 13 Hex pairs, I use the pairs. Try either turning wep of completely or entering 26 1s. Remove your setting for your ap in Configure Wireless Networks screen then reconnect.

Okay, I've basically removed all security from my wifi setup. I live in the middle of nowhere so it's not a problem - although once I get the wifi working I'll try and get the security going again.
I still can't get a connection
...stop the press!
Okay, I had a thought...maybe I can't connect because of the speed?
the router is a 11g but supports 11b (which is what the QTek 2020i/XDA IIuses) - sure enough, I had the 11g only option selected - DOH!
removed that and I've managed to connect without security.
I assume this was my problem all along...will now stick the security back on and try again
Thanks again Paddy
Cheers
Wayne
Update: I've now managed to get the wifi working with WPA-SPK authentication using TKIP encryption
all along it was simply a case of me having the speed on the router set above what the PDA was capable of! I'd set this ages ago when I first setup my wlan and had forgotten about it cause everything I use is 11g

Doh!...nope, not working again...back to the 169.254.x.x problem.
It's obviously to do with the encryption this time. I'll try some other variations - at least I know that it can work :roll:

Ouch......
No hard feeling, glad you found the problem
Paddy
bump!
pretty much same prob!
i can get an ip, have to check what it is, it tells me its connected on the scanning network page but on the other bit it tells me its available or connecting but never connects!
i've turned wep off and still no joy!
its really starting to drive me mad!
please please someone help
Take a read back through the last lot of posts between myself and MacPad - I think you'll find the answer there.
For me, I had to totally disable my security and everything else - I could then connect. Once I'd done that, I managed to use WEP with a 26 digit key - start by using something like "0" 26 times...make sure u count as u type them zero's in though as if u get it wrong it won't work!
apart from that, not sure what to say. If you're getting the 164.x.x.x ip address though then as MacPad said, it's to do with the security.
I would mention that the XDAIIi/Qtek 2020ii use 11mbps wifi (b) and not 54mbps (g) so make sure u've got ya router configured to allow both types of connection...this eventually turned out to be my main problem - doh!
Cheers
Wayne
ok now im home ive re-read and done the things mentioned. with a completely unsecure connection i can get a connecation, but the moment i use any kind of encryption (im using wep 64bit, but tried 128bit as well) no matter what key i use i get a split second of connection then its gone!
firewall is not on either.
any ideas??
thank for the suggestions guys im finally progressing

Wing loses Wi-Fi connection randomly

I've had two Wings with the same issue: no matter what access point I connect them to, the connection drops randomly.
When this happens, the icon in the display still shows as connected (two parallel arrows), the Wi-Fi status shows the device is associated and has a valid IP address, BatteryStatus shows the device is connected to the AP, and Comm Manager shows green on the Wi-Fi icon.
But, you cannot browse the Internet nor can you synch email (I use POP3, Live and Exchange direct push messaging).
Putting the device to sleep and reawakening it instantly reconnects Wi-Fi as does shutting the connection down and restarting it in Comm Manager.
This happens on any Wi-Fi access point, and I have tried about six: multiple T-Mobile hotspots, WPA2/AES and WPA/TKIP encrypted hotspots and completely open Linksys WRT54G access points.
This HAS to be a setting in WM6 or in the adapter settings somewhere. T-Mobile hasn't got a clue and many searches on the Net haven't turned up a clue.
Has anyone else seen this?
I too have noticed this
Its weird mine too loses connection I had always thought it was my WiFi at home because its a crap router but i guess not anyone have a fix?

HTC Touch WiFi Problem

Hi All,
I too have a strange WiFi issue. Here goes:
My phone is able to connect to free WiFi stations and the WiFi station at my parent's place. When I try to connect at home, it connects but I am unable to browse.
I previously used WEP encryption and have also tried removing all encryption...but no luck.
Here are my current router settings:
Band 2.4 GHz B+G
Mode AP
Channel 9
Authentication Open
Preamble type Long
Broadcast SSID Disable
Encryption None
Use 802.1x Authentication Disabled
Phone Details
HTC Touch
Browser Netfront/IE
My laptops, DS Lite, Wii can connect and work with the router...
Any help will be highly appreciated
Check that you don't have MAC ADDRESS FILTERING at the router. It may be hidden under Filter settings, like my D-Link is. This may sound trivial, but more than once I forgot about the MAC filtering.
If that doesn't help you, then just to narrow it down, at my home I use WEP and disable SSID broadcast also, and my Touch can connect fine, and fast.
Scratch the last post! I had the same problem with my TOUCH..Just put the power level to the max (i.e. go Start -> Settings -> Connections -> Wireless LAN -> Power Mode -> and slide all the way LEFT to Best Performance) and all hail ..your problem solved
I also use a Touch. I put the slider all the way to the right (Best Battery) and I connect fine. You people must have a big house, or a crap router?

Wifi Problem!
Hi guys,
I've got a problem and I'm hoping you can help me out..
I've got a HTC TOUCH and when I got it the Wifi connection was working just fine.. I could connect to any WIFI network and Browse the internet.
After a month or two, my phone wouldn't connect to my home wifi network anymore. And neither would it connect to any other wifi networks (I tried!)..
I've been all over the internet trying to figure out what could have happened and if someone else was having these problems to.
I just can't find the answer and I feel like I already tried everything I could think of..
Hope some of you knows what to do..
I'd suggest looking at the Touch forum... I've got no experience of Touch devices, but it may be a Radio ROM issue...
kinda same issue I am facing ! donno
MY HTC TOUCH never connects to NETGEAR WIRELESS ACCESS POINT
but finds LINKSYS routers in a jiffy :O
are Wireless Access Point and.. Wireless routers different
they both emit diff. signals ?
I have the same issue with a TYTN II, can connect to the wireless, but can't open any web pages.
problem with htc & WPA-PSK passkey 25 characters
My htc tilt connects almost everywhere, but i have a problem with wpa-psk at work. The password is from 25 characters, I read some articles what WM cannot handle such length. Maybe it's possible to edit somehow the registry?
I have the same problem guys, what can we do to find a solution i tried everthing i could, and i even tested it out with my 2 wireless routers, and at public places it connects (at home it doesnt connect though).

HTC Touch wifi solve
I had the same problem with my htc in WEP it dosen't browse, I changed the router to a better wifi protection like WPA-PSK, connected and worked fine, for some reason it only work's fine for a couple of minutes, I readed this post to put the sidebar in best performance and now everything works fine. An advice don't use WEP it's not secure at all.
http://en.wikipedia.org/wiki/Wireless_security maybe you fine this interesting and helpful.
I'm running into a problem were I can connect to an AP at work and surf the net fine but when I disassociate I cant connect to it again for a whole day. The AP must be saving some info and therefore will wait for the DHCP lease time to finish before allowing the touch to re-connect. I tried my laptop and was able to connect 3-4 times and never have a problem so it is isolated to the touch and windows mobile 6.1. To find some more info out I was able to clone the mac of the touch and use it as the laptops wifi cards mac. It connected fine on 3 consecutive tries.
Maybe windows mobile is missing some commands when disassociating from an AP and as a result leaving info out in nowhere land confusing the router.
Thanks for any help!
ok, here's me joining the club... dunno what happened... working one day, getting crap the next.
exact same problem as everyone else...connects to the wireless network, then when you try to surf, page cannot be found...
Exact same problem here.
In the beginning everything fine. Connecting to my home WiFi and using the internet without problems (weather, stocks, opera, email, google maps, even skype voip).
Then, last month, all programs are unable to find anything on the internet, although the device reports it is connected to my (unchanged) home WiFi.
All these programs work fine when the device is connected to the internet through activesync (usb cable).
Also this whole time I have been using my home WiFi with a laptop from both Vista and Ubuntu, with no problems, so I guess it's not the router.
Also have read in other fora about these wifi working - wifi not working "cycles" other people have had, with various WM devices. And various tricks like shutting wifi off and immediately on again.
I even hard reseted the device. Problem still there.
WTF?
Connected once only
Connected once only for a few minutes to my home router dir 310 D-Link, worked fine and fast. After that I closed the connection. Next day I tried to connect but my HTC Touch 3G doesn't see the router. I see any other routers, but I do not see mine. I connected to some friends routers with WEP and WPA encription just to be sure the phone working. During this I didn't changed the router or the phone settings. It is very strange. The problem maybe comes from the router.
I'm having the same issues with my HD2. Looking all over the place and seems to be a common fault, but thus far with no cure, I tried the power save mode
From new it worked like a dream, but then one day it would connect to AP's but act as if not connected. I flashed my ROM with the VERY impressive Merlion Leo v 2.66 and it all started working again. Then yesterday, it stopped again. I don't want to reflash, so I'm working hard to find a cure, and will report as soon as I find one.
---EDIT---
I've found a cure (for mine at least), not sure if it will work for everyone, and haven't managed to test it at any other AP's except for my home Router, but all I did was set the network card properties (Broadcom 802.11 DHD Network Adapter) to 'Use server-assigned IP address' instead of 'Use specific IP address'. I'm not sure why this worked as there was no IP address conflicts because there were no other devices connected to my router when I had problems, but it works for me, hopefully permanently
Good luck.
Try this. Its work perfect for me!

Wifi finally connected but cant browse

ok - i have gone through about 6 roms now and im constantly getting the same story.
i primarily use CM based roms cuz those are the only ones that seem to connect to ad-hoc networks shared from my computer. when i use CM7 roms the internet constantly connects and disconnects and when i use CM6 roms the phone says im connected but the PC doesnt see any present connections.. not even with connectify or the other hotspot programs seem to help
its strange cuz i also have an aria with a CM6 rom which connects flawlessly but the HD2 cant even be seen on the network.
PLEASE can anyone help me out with this problem? I've been awake for the past 2 days trying to fix this problem from all sorts of angles and i still cant connect to an ad-hoc wifi
i just tried connectify but the problem is the same, it says im connected but still there is no data coming from the computer. my MAC address appears fine so i have no idea what is causing the problem
not even changing the channels, editing wpa_supplicant, using static IP or DHCP... nothing helps..
just realized that if i try to connect while other devices like my aria are currently connected, the other devices get disconnected from the network.. no idea whats causing that but could use some insight
There is another longer thread with someone having the same or at least very similar problems. All non-Sense builds he's tried have wifi "connecting", but not actually transferring any data. When he loads up a Sense build, it all works fine. I'd look it up, but search unavailable for "10 minutes". I did comment on it though.
You wrote you try to setup an ad-hoc WiFi connection. This means you connect two devices together, not to a network (if you want to use your laptop as Internet bridge it's a more complex config).
You're talking about DHCP in ad-hoc connection... Do you setup a DHCP server on your computer (is this even possible)?
You said when you have other devices connected... this is not ad-hoc.
I think you try to connect the wrong way, sorry if I misunderstood but you have to provide more info for me to help.
As general advice:
Check for your ROM thread as initially their was a problem with all devices (with Android on HD2) having the same MAC (has been solved)
Start first to try to connect to a "normal" WiFi network
Make sur of the network config (try with basic b/g instead of n, n+...)
First step could be to setup a basic b/g network with DHCP enable, SSID broadcast, no security (wep,...): the kind of network you have when you take your access point out of the box.
No other advice... hope this will help.
Check the IP you have on your phone when connected. If it's kind of 169.xxx this can't work. It's auto IP from the device itself.
thanks for the response mate. Unfortunately, there are not many unsecured "routed" wifi connections available where i am to test - thats why i have to rely on the laptop to feed internet to my phones through an adhoc network.
let me explain what im doing:
im currently trying to use internet sharing from my laptop on my phones - i have 2 android phones, an aria and an HD2 - both of which connect to the internet through an ad-hoc wifi connection to the the laptop which has LAN internet connection.
the only way to connect is by issuing each device a static IP
eg. laptop - 192.168.0.1,
aria - 192.168.0.3,
HD2 - 192. 168.0.2
whenever i try to use DHCP i get "obtaining IP address" from the phones until it auto-disconnects.
using a static IP-Config, the aria connects and browses effortlessly. But the HD2 wont. Just says "connected" but the pc says "waiting for peers to connect" and doesnt feed any data to the HD2. Additionally, i found out that if the aria is already connected while attempting to connect the HD2, the aria gets kicked from the net..
if it helps, my rom is CMN V_2.0.. its the only one that gets me "connected", so to speak..
Then I will not be very helpful as I seldom use ad-hoc and bridge connection.
I connect my HD2 to my home network only (works in WEP or WPA anyway).
Just what I know:
1/ for ad-hoc you can't use DHCP (or you may have to activate a server on your laptop, this will add complexity to your setup)
2/ ad-hoc is only between 2 devices (1 laptop and 1 phone for ex), it could explain that when you connect the HD2 the other one is "kicked out".
3/ On your laptop you have to bridge your connections. Anyway, if with another device you can connect and broose, then your laptop setup has to be ok.
4/ if you're connected you may find a good IP in the HD2 (anyway if you use fix IP it has to be ok).
5/ to connect to a server you need a DNS. this is maybe what is missing. Usually when you connect to an access point you use the "AP IP". Not sure it can work here.
Try to manually put the DNS address in your HD2.
Just to make one test:
a/ from your laptop "ping" an Internet server (xda for ex).
--> Start menu, type "cmd", in the cmd windows type "ping server_name"
b/ from your HD2 try to connect with the IP instead of the server name.
This is the puprose of a DNS, to give your device the IP of a server.
NB: to find the DNS server used by your laptop:
In cmd type "ipconfig /all" it will give some info, you may find your DNS in it.
Sorry, no other idea...
I read again what you write and I think you can forget my previous post.
The answer from your laptop is different with the two phones.
I don't think it's a DNS problem.
Sorry, I will be useless! Hope someone with the same network config will help.
My home network is totally different.
If it's specific to your rom you can try to check in your ROM's post if other have the same problem. If no, try to ask there is someone has the same connection setup.
Edit: check this link, it seems that many people with non-sense build has problem with WiFi (I use sense build, always):

i would use a sense build but it seems all of them take up quite a lot of space from internal storage - im always left with 500-400Megs from the 1GB of space
its just odd because when i had a G1 (before i got my HD2) it connected effortlessly as well.. even more so, both aria and g1 could be connected to my laptop's adhoc simultaneously
OOOOHHH!!! i just rememberd hearing something about internet pass-through, but im not sure how ti works.. i will give it a try

[Q] Wifi issue. New findings?

Hello, been a long time reader from my G1 to my G2 and now my nexus 4.
I am unfortunately not able to use my device on certain wifi networks which is a real bummer.
Being that i have a background in diagnosing computer problems in my real world life, i thought i would post my findings as i found some interesting things!
First i will say that the network i will use as the demonstration is secured with WPA2 PSK AES security and encryption.
I can connect to it and often find i have problems on the first connect to the network. By this i mean if i have made my wifi settings 'forget the network' and then try to connect again.
On the first time it seems to indefinitely hang, showing the message 'authenticating' on screen next to the network and if i long press on the network name and press modify, the dialog shows that i have a link speed of 1mbps.
I can usually get past this by turning wifi off and on and then reconnecting, at which point it will connect straight away and have a normal link speed. (in this example 72mbps).
After i am connected, i find that the following does not load:
-browsing webpages through chrome does not load
-the wifi icon turns grey
-play store cannot load anything
I find that i get assigned an ip address by dhcp correctly too with the right gateway and dns.
I decided to download a network tool to have a better look. I use fing personally.
I found it very interesting what i found, which no other threads about wifi issues mention.
Network discovery found every device on the local wifi network.
I was able to scan the services of my computer which is also on the network and it found everything, including a http server which i run which i could browse to.
In fact i could do everything through wifi with this device and most others.
Again it got interesting when I then took a look at my gateway, the router.
I had discovered its mac address which i can verify through my computer is correct which to my understanding, being that i can communicate through the wifi, means that i have the information available to send information to that physical device?
When trying to scan services, i find nothing, which is not true, at the very least it exposes a http server on port 80 which my computer can access.
When trying to ping i have 100% packet loss.
So at this point it is only the gateway i cannot access.
So i figure i could setup another computer which is connected to the network with a wire to share its connection through wifi onto that network and then i have a standin gateway?
I connected this computer through wifi to the network and pinged it succesfully with my phone. I then turn ICS on my wired adaptor to share to my wifi adaptor. I ensure that the wifi maintains an ip address in the right range and subnet.
I then try to ping that ip with the phone and it then gets 100% packet loss.
Could this be that when a device is configured to act as a gateway something changes about how it handles any packets sent to it that the nexus 4 is currently in compatible with?

I have found a bit of a workaround that i can use!
When i said i turned on the wifi and ICS i did the following:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the wireless to 192.168.10.x and gateway to my router 192.168.10.10
-I then tested.
I ran through this again but slightly different:
-Turned on wifi.
-Connected to wifi network.
-Turned on ICS on my wired network to share to my wifi
-Observed that my ip changed from 192.168.10.x to 192.168.137.1 with no gateway or dns.
-I decided to change my ip on the phone to 192.168.137.5 with gateway and dns as 192.168.137.1
-I then tested. And it works!
I know this doesnt fix the wifi issue itself, but for me, this makes a big difference as i can now use wifi at work where we also have poor mobile network coverage.
Edit:
Additionally i previously tried to setup this same computer to host a wifi network to share the connection using 'netsh' and creating a 'hostednetwork' but i found i was in the same situation where i still couldnt get the internet.
