3Com OfficeConnect 11g ADSL wireless router

[Guest chrisw000]

This relates to issues with SECURELY connecting phone Wifi to 3Com OfficeConnect 11g ADSL wireless router - and the solution I found to get it to work - woo!

Got an O2 XDA Mini S today - and have just spent literally 10 hours getting the WiFi working..... so hopefully this will help other people with this phone / router.

The short answer to the problem (as mentioned elsewhere on this forum) is to do with the routers DCHP Server…. So turn off the DCHP Server on the router and force IP’s on the phone.

The long answer…

The issue is caused by the router DCHP Server. Why? The router “talks” back to the phone’s connect request using IPv6 – the phone doesn’t understand the response – seems it wants to “talk” in IPv4. After a failed connection attempt, look at the phone Settings>Connections > Network Cards > Network Adaptors > SDIO WLAN Wireless Adapter > User Server IP is ticked, the greyed out IP address shows something like fe:230:xxxx etc – this is the IP info in IPv6

So….. to correct:

1st off – my setup:

* The phone I’ve got is an O2 XDA Mini S.

* I got this to work after doing a HARD reset – doubt that matters either – unless like me you’ve totally screwed loads of settings whilst trying random stuff to get it going.

* After the hard reset I avoided installing the O2 stuff using the soft reset trick mentioned elsewhere on this forum.

* The router is running firmware 1.28 – which is not quite the latest version….

* The router is applying MAC filtering to wireless connections

* The router is set to 11g only  but try b+g first incase your phone doesn’t do G

* I’m using WPA-PSK for encryption

Having said all that – I doubt it matters due to the nature of the issue….

Log onto the router

* Turn off DCHP Server - Apply

* Fix all computers/laptops etc. wired and wireless into the router. You’ll need to manually set their IP Address, Subnet mask, Gateway and DNS Server.

* My router is on 192.168.1.1 - so I started fixing the machines from 192.168.1.2 and up. Obviously each machine needs it’s own unique IP. Use the router address for gateway and DNS Server.

On the phone

* Turn on the WiFi

* Goto the Settings>Connections > Network Cards > Wireless > YourNetworkName….. and set your encryption type + key….. OK it

* Now goto Network Adapters > WLAN Wireless Adaptor

* Select Use specific IP Address

* Add your address, subnet, gateway,

* Switch to Name Servers tab, enter your router IP for DNS

* OK it

* Ensure the “My network card connects to “ says “The Internet”

* OK it.

* Turn the phone off

* Turn it on

* Turn on the Wifi…. It should connect

* Internet Explorer…. Goto google….

Thanks for the info. I've got exactly the same hardware combo as you. I've been having trouble but presumed it was the G side of the router confusing the phone which I hear is B only in the O2 configuration. I had got things to connect when the router was set to B only but then another laptop on my network spat out the dummy as it seemed to insist on G. :roll:

Sounds like a solution. I'll try it. Fixed IP is a pain though. It means I'll have to fiddle with the settings again if connecting to a wireless hotspot. DO you really have to get all your PC to use a fixed IP too? Can't they use a pool of say 192.168.1.2 to 192.168.0.100 and you can manually give your phone 192.168.1.101?

btw,does avoiding the extra O2 stuff mean the phone is G enabled?

Seems to be working for me now. My setup:

Router

- Mixed B/G (long range)

- DHCP enabled (pool 192.168.1.10 to 100) and used by other devices on the network

- WPA-PSK encryption (TKIP)

- SSID broadcast enabled

Phone

- Static IP of 192.168.1.101

- Correctly picked up the type of encryption when the network was detected and asked for a key.

- No idea if it's connecting at B or G rates. I don't really care as the device has to be the bottleneck speed-wise anyway.

No idea how to get it to "prefer" my own network rather than announcing my neighbour's network first when I enable WiFi.

No idea why connecting ActiveSync via USB to my PC complains about not getting a valid IP address (but works anyway). Probably something else I'd fiddled with.
