Both TKIP and PSK use essentially the same WPA standard, just different ways of encrypting the same thing (hence WPA-PSK TKIP and WPA2-PSK AES).
PSK stands for Pre-Shared Key and depends on a passphrase to connect devices. TKIP is just the encryption protocol that the has been included in the WPA standard.
As far as your question, your device (the Captivate) is looking for both WPA/WPA2 PSK protocols.
I would recommend switching your router to WPA2 PSK AES anyway as it has shown to be more secure than the standard WPA-PSK TKIP.
Your wife might gripe, but if she's also using a cappy, then it won't matter since it's looking for both protocols - just use the same passphrase. For any other device, it takes a minute to change the settings and get everything up and running.
All that being said, your router settings might not have anything to do with the wifi problem. Before I started flashing ROMs, I had to constantly switch my WiFi off and then back on before it connected.
Hope that helps and wasn't too confusing.
I have an old router with WPA/TKIP. I will boot it up tonite and see if my 2.2 Cappy can use its wireless network.
Sorry haven't tried it yet... for sure tonite!Hey rubiconjp - how did it go?![]()
I just got my captivate a week or so ago so it was already updated and i was having the same problem i could connect for one day but the next day i just got "scanning" or "obtaining ip for" but never would connect. my solution and so far it seems to be working is i set a static ip for my phone and it connected immediately i turned the wifi off then back on and connected again no problem. i know this is not a fix for open networks like at school or work {really have not tried at those locations yet) but for home it works great.Ever since updating to 2.2, 7 out of 10 times, my phone will just show "scanning" and never jump on the known, saved wifi profiles when I get within range. I have tried the FXR program and, unfortunately, it didn't help at all.
since she's a technophile, she should really move to AES instead of using TKIP for 2 reasons: AES is more secure AND much faster (way less overhead) when compared to TKIP and WEP.I fear running into the WPA (not WPA2) problem on other routers, but am ok at home now. Of course, not everybody has a 2nd router lying around (I moved into a technophile's house, and she didn't need my router.).
