No wifi routing on 3COM wireless router? - EVO 4G Q&A, Help & Troubleshooting

For some odd reason I am unable to use WIFI at work on our 3COM wireless routers. I can connect to all the access points fine, but it never routes. I can ping other internal IP addresses, but I am not able to ping public IP addresses outside of our network.
I started looking through logcat and found that it is setting the gateway to 120.123.1.0 when it should obviously be 192.168.1.1. I looked everywhere in the router settings and the gateway is specified as 192.168.1.1. This is obviously a problem! Why in the world is it picking up this bogus gateway IP address from these routers?
I've had no problems with any other routers and an office neighbor is able to get wifi just fine on his iPhone. Any clues?

Well it is definitely just a gateway issue. I opened a shell with adb and set the gateway to 192.168.1.1 manually and I was able to to access the internet via wifi on the 3COM wireless router.
Does anyone have any idea why the EVO would not obtain the correct gateway? Every other system on the wireless network gets the right data from the DHCP server. I don't care how much of a long shot your suggestions or ideas are, I am looking for any leads to investigate. I've already double checked everything in the wireless router and DHCP server and the mysterious gateway IP (120.123.1.0) is nowhere to be found.
IP, netmask, DNS, DHCP server, and lease time are all coming in fine.

XDAIIi and Wifi

I just bought one of these and can't get it connected. I have a netgear wg602 access point, and have configured the IP address manually (I know IP, dns and gateway are right)
I now have it saying it's connected, with right IP address. My DNS and gateway are set up for the wireless adapter in network adapters. The signal is average. The XDA says wifi is connected. The access point even says it's authenticated and associated - same as my other stations.
Only problem is, internet explorer doesn't find any web pages - says "The page you are looking for cannot be found" (works fine through GPRS)
Also, terminal services times out trying to connect to an internal IP address (to eliminate DNS as a problem)
So, anyone know how I troubleshoot network problems - it looks like a TCP/IP issue? Can't find ping or arp etc. I've also tried an IP address that I know works on the network.
thanks for any help
Dave
Can you ping the XDA from any other station on the network ?
Is your network 802.11b or 802.11g or both ?
both
No, I can't ping the xda from anywhere else. The access point is both. I have two other stations - one on g and one on b.
thanks
Dave
Must be something in the config on the XDA.
If you look at the settings for the WiFi network card on the XDA what does it say it connects to..."Work" or "The Internet".
Try changing that and see if that helps.

does NE1 have the answer to wifi not connecting to the net

im trying to get an internet connection through my wifi connection. i have done search's and lots of people seem to be asking the same question but nobody has the answer.
at the moment i can access my c: using an application called Resco explorer. but i can not connect to the internet. im not sure what setting i should have on the wifi manger and on my pc. im also using AOL as my isp.
PLS PLS help :lol:
Edit:
also i can not connect to activesync (version 3.8.0) via wifi. maybe if i was able to connect to this the internet would work as it does when its docked??????
looks like a no then
I got mine working but setting my wireless network adapter to connect to "Work".
Under Settings>Connections>Tasks>Manage existing connections>Proxy Settings> check the "This network connects to the internet" box
then
Under Settings>Connections>Advanced>Select Networks> "Programs that automatically connect to the internet should connect using:" to "My Work Network" (and the same with one for private network)
Also in your active sync settings, make sure your connection settings allow network (Ethernet) and RAS connections.
From previous research around this, i'm pretty sure you can only use the internet pass through under "WORK" settings only.
*thought i'd better register and contribute as i've gained a fair bit from this forum.
no good anyother ideas. i have searched through hundreds of threads and still no go
help pls
Make sure you have "Enable Netbios over TCP/IP" checked in your TCP/IP Advanced settings.
i have done this on both my wifi network and my isp network.
still not working
Have you checked if you're getting an IP address from your Wireless Router's DHCP server? Also DNS settings and Gateway address should be there.
You can check this easily by using vxUtil (free )
these are my settings:
tiacxwln1 - tiacxwln compatible wireless
Ip address 192.168.0.2
subnet mask 255.255.255.0
default gateway 192.168.0.1
primary DNS 192.168.0.1
secondary dns
primary wins
seconfdary wins
DHCPs server 192.168.0.1
under serial usb
IP address 192.168.55.101
subnet mask 255.255.255.0
default gateway 192.168.55.100
primary DNS 127.0.0.1
Getting this error when I tried to allow my broadband connection to share with my wifi connection. If I unplug the wifi connection and try and share with another network I don’t get any errors.
Internet connection sharing (ics) cannot be enabled due to IP address conflict on the network. ICS requires the host be configured to use 192.168.0.1 please ensure that no other client on the network is configured to use 192.168.0.1
hmmm ... ever had the same problem. all devices are able to connect to the same router except mine sx66.
then i change the router's channel to '1' .. tada .. now everyone is connected. it might sounds silly, but it worked for me.
try changing your ap wireless channel.

i found the problem with activesync 3.8 and 4.0 somehow, so i reverted back to 3.7, now wifi can sync.
afaik, connecting to internet has nothing to do with activesync. its a direct connection to wifi router. use work location and check the proxy settings if u hv any? (at home i use connect to internet without proxy, at work i use connect to internet with proxy).
Also, for Activsync with wifi, make sure that the WINS server address is that of yr PC u want to sync with.

[Q] Froyo WIFI problem with dynamic IP

Since installing Froyo on my Desire, I can not connect to my local wireless router (Belkin N1 Wireless router) when using a dynamic IP address. Previously (on eclair) this was no problem what so ever.
When I try connecting, it keeps saying it's trying to aqcuire an IP address, but nothing happens.
When I check the routers overview of connected devices (DHCP client list), I see this:
ip address: 192.168.2.4
host name: android_f07d6a45ÿÿÿÿþÿÿÿ (yup, strange characters)
I tried connecting to my macbook via WIFI, and that worked without a hitch.
After restoring factory settings on my Desire, factory settings on the router, installing newest router firmware... I tried again, but to no avail!
Then I gave the Desire a static IP address and presto; I could connect to my wireless router without a problem.
In conclusion:
Before Froyo: connecting to wireless router with dynamic IP addresses = no problem
With Froyo: can only connect to router with static IP and Desire's hostname contains strange characters
Most other wifi networks seems to work.
Anyone else having similair problems? Is the Desire's strange hostname the problem?
This was a problem for me with Eclair too, and yes I'm still experience it, the only solution I found before was "wifi-fixer" or what ever the app was called (it's found via the market). But it did not work all the time... :-(
Update: I can connect to Dynamic-IPs without noticing any strange Chars. But its the "unable to..." that's similar to your's.
static IP won't help
I'm a little frustrated becouse even static IP is not helping
can you tell me how your exact PHONE config's are?
like gateway dns and so on,..
THX,

These settings should be different from router to router
I can give you mine, but I doubt it will help you:
IP: 192.168.2.4
Gateway: 192.168.2.1
Subnetmask: 255.255.255.0
DNS 1: 192.168.2.1
DNS 2: BLANK
Depening on your router and settings, you might have to change the ".2." in all of these to ".0."
The "4" in the IP address is also free for you to chose (must be available though)

Hotspot problem, limited connectivity/ no internet

This is how i fixed the problem. after 2 days of RND
Activated hotspot on my arc, and waited for my laptop to connect. After you get connected your laptop adapter will show limited connectivity/no internet.
Now go to the market and download "Network info"
open network info and find out the IP address of your device.
it will be something like 192.168.43.1
now go to to your wireless setting of your laptop, and change the settings to DHCP to static.
if your phone has IP 192.168.43.1
Then configure your laptop's ip 192.168.43.2 subnet 255.255.255.0 gateway will be your phones IP. ie 192.168.43.1.
dns 8.8.8.8
8.8.4.4
DONE

Failed to obtain IP.

So, weird thing started to happen last night. Both my Samsung devices ( my 2014 10.1 and my S4) started failing to get an IP from my wifi network. It would see the wifi network and report a strong signal, but would fail at the obtaining IP address. The IP assignment is handled by a Windows DHCP service running on a domain controller. I work in IT so I have a fairly extensive lab at home with routers, switches, servers, domain controllers, etc. The wireless access point in my home is a WNDR3700 with no WAN port config as my firewall/routing is done by a Cisco ASA 5505. All the 3700 does is provide wireless access to the network, essentially it acts solely as a wifi AP. Every other wireless device on the network is functioning fine including 3 laptops, a Blackberry and two other Android tablets ( Asus Transformers). So I know nothing is wrong with the dhcp or the AP in general. It's not a security issue as it is not failing on authentication, just on obtaining IP. So as a workaround I configured each one with a static IP and, of course, everything works fine.
One thing I noticed that seemed odd was that when I went to change the IP addr the address that was already in there, but greyed out sort of, was the wrong network for my home wifi. The phone and tablet both looked like they had a 192.168.1.0/24 address whereas my home wifi segment is 192.168.0.0/24. So maybe that had something to do with it. At the office now and both my phone and tablet have no issue connecting to our Cisco APs and getting a dhcp config from a Windows DHCP server. So pretty weird situation. I'm fine with leaving them on static config while on my home wifi network. Was just wondering if anyone else has seen this before?
Thanks
For any that might be interested. I used inSSIDer to find a less crowded channel for my 2.4 ghz band at home and both my Samsung devices are connecting and receiving ip addrs now.
