WiFi Not Working

All was well last night, didn't notice it until this afternoon. The HTC Desire isn't seeing any of the WiFi signals around me. I was using WiFi to connect. SEttings on the phone show everything is on. Could I have downloaded something that would keep it from working?     

I have no problem seeing my Wi-Fi but as it requires a long password is there any way of copying and pasting the password in to access Wi-Fi?

I used a password generator to generate a random passowrd and it contains over 60 random characters so I store it in a text file and when needed I can cut and paste the file into the password field. Lazy I guess but at least its accurate and quicker. Apart from that I use the cut and paste facility all the time and I know it is available on Apple iPhone so I am somewhat surprised it isn't available on this phone or so it seems.

Interesting videos but as you guessed does not apply to a text file. Clearly copy and paste is available from web pages so it must be only a small step

Can your Desire "see" your wireless network?  I'm sure you'll get your Belkin to work with the right settings.

I connect the Desire automatically and seamlessly now to either of two routers and a couple of access points on my WiFi network as I move about.

Make sure you haven't set your WiFi to CH 13 'cos the phone won't see that at all. I don't know if you are running straight Wireless N but I'm using a mix of 802.11 B/G/N mixed WiFi on the DLink Router (DSL-2730B) gateway at home and Wireless-G on a Billion BiPAC (7401VGPR3) gateway router at the other end. (The other couple of APs are running G)  

In other words I don't know if my Desire is actually using or able to use Wireless N at all - maybe just G which is fast enough.

Just as an aside, my LAN is spread over two buildings about 800metres apart with a wireless bridge joining them but I'm running a router gateway at each end as the wireless bridge can be a bit slow sometimes. However I digress.

The whole LAN Workgroup name and WiFi SSIDs are the same throughout. I'm using a security settings of "Auto(WPA and WPA2)" on the DLink and "WPA-PSK" on the Billion. Your wireless key is case sensitive so ensure you enter it the same as on the Access point(s).

Now as I move about and between buildings the phone auto connects AND doesn't then use Telstra when away from my WiFi unless i say so.

(As an aside, with two routers on the same network instead of getting really fancy with subnets I split the IP address range for each router and hard coded all IP addresses and gateway on the peripherals so each device would use the right router) The phone however just uses DHCP.

It also works well on other WiFis such as at Maccas.  

Thanks guys... actually Im running at Channel 6 with B/G/N option. Duno why it can detect but unable to connect to the router.

*BUMP*

Ok, first time here, thought I'd pop this here as its the same issue... I think

I have a Belkin_N1_A180E6 running b+g+n as this is the only option (other than off).  My Desire can see the network at all times.  I have checked and it's running channel 6

I'm having intermittent connection, it does all of the following:

Connects automatically
fails to connect, no "connecting" message, no "disconnected" message either
fails to connect, says "connecting" then goes to "disconnected"
Tells me my password is wrong (I know its right, I can see that)

It also seems to "throw" either the ipad or one of the other PC's off the network by causing an IP conflict, the PC's may have been caused by my Xbox but the ipad was 100% the Desire

I have tried the following:
Check the router - no MAC filtering or any kind of service denial set up, passwords match
Reboot the Desire - It can't seem to shut itself down so I have to get trigger happy with the battery.
Used the Airplane on/off
Forgotten the network and re-aquired/configured
Turned the WiFi off/on
Reset the router (pulled and reconnected the power)

Occasionally, after time, like when I get fed up of trying, it connects on its own :s

The question is this, am I simply "screwed" in terms of having the wrong router? (i.e I can't disable the n)

Oh, and I have connected to another router without any problems...

I can use wifi in cafe's but not at home. I'm using a netgear router with b/g option. I was able to connect when I set the network to open but cant connect with either wep or wpa. The network is visible and the phone says connected but cant open any web pages. I set the router to channel 6. I'm living in Vietnam by the way, and set the router to g because I read on another forum not to have mixed mode b/g. My HTC Touch HD can connect on every setting.
