WI-FI issues/ invalid argument message

I spent about 20 minutes on the support line with apple and you have to change your ip address to something started with like a 192. if your ip address on the current ipod that is giving u the "invalid argument" then the ip address is wrong cause it shows up as a 162 i think and thats bad. so change the ip address from your ipod its self. just cause the ipod says its connected still means your have to change the ip address

You should not have to manually add an IP address unless your router is 1) old or 2) does not have updated firmware. The problem lies within the router firmware that controls DHCP (automatic IP address assignment for connected devices).

I also unplugged my wireless router (with itouch in range and on), waited five minutes and plugged it back in. *The itouch wireless now works!* I did notice that something wasn't right with the wireless settings. I only had an IP address and Subnet Mask showing, the router line was blank. So once the router was turned off and back on it created a router ID, which it obviously needs for the wireless to work. I hope this also helps everyone else. Eventhough all my other wireless devices were working, the router had to be off and back on to resend the id to my touch.

Just in case you don't know how to check your Wi-Fi settings:
Go to settings, choose Wi-Fi, click on the blue arrow all the way to the right of your chosen network. This brings up all the settings for your network. IP address, Subnet Mask, Router *& DNS* mine was blank, should have number's.

this solved my problem. thanks.

I have the same problem. But i was at school and had no trouble getting online??

I had the same issue. What worked for me was this: connect to your WiFi hotspot, then click into your network so you can see all the settings. Click the "Renew Lease" button toward the bottom of the screen. Once I did this, I was able to connect to the internet. Hope this helps!

I get "invalid argument" only when I'm using my campus wifi (I had to set up a profile for that to work) and only when I'm in a room that has a weak signal from it. The problem in that case is solved by moving somewhere with a stronger signal and/or reinstalling the profile.

I had tech support call me, and the solution was to restart my computer _and then_ reset the network settings on the iPod. I'm not sure it will stick, though.

I've since noticed that I also get that error at home. Basically, if I start up my ipod and immediately try to check something on the web, I get various different errors that almost always disappear a few seconds later when it connects online. So I usually ignore those errors.

Worked great thankx for the good advice!

I was having this same issue with being seemingly connected to wifi and getting the invalid arguement error. I just unplugged and restarted the router and now everything is working on my new ipod touch 3G. Thx all!

After I downloaded the new update, I now I get "operation could not be completed inalid argument" on anything that needs the internet.
I've read some of the discussions but no real fix, I feel that this is a Apple issue and they need to fix this ASAP there alot of people having this issue
and enough to warrant a fix.

I have 3gen/8g ipod touch and solved the problem by switching on/off the wifi in settings.

I'm having the same problem to. I was using the internet then out of the blue it stops and i get an invalid argument message. The message appears when trying to use safari, itunes, and app store. I have a 1G ipod touch and recently upgraded to 3.1

Hi,

Does the issue persist after restarting the wireless router and the iPod touch?
You can restart the iPod touch by holding the Sleep/Wake button until the red slider appears> then slide to turn off> and turn the iPhone back on by pressing the Sleep/Wake again.

Also, this article: http://support.apple.com/kb/TS1398 provides general tips that will resolve most Wi-Fi issues.
