iPhone and wi-fi issues

iPhone 4s, bought December of 2011.
Linksys WRT54GL running DD-WRT v24 std.

Wireless Mode: AP
Network Mode: Mixed
Channel: Auto
SSID Broadcast: Enabled
ACK timing: 2000
Security Mode: WPA2 Personal
WPA Algorithms: TKIP
16 character shared key
Mac Address white list is enabled.

I upgraded to iOS 6 a while back. Everything was fine until last week. I happened to notice my phone was not connected to wi-fi, and the wife's lappy was. The phone couldn't even see that my network was available. Started goofing around, changing settings, rebooting phone, etc. Finally, adjusted wi-fi security to off, saved the settings, and the phone connected. Re-enabled the security and the phone stayed connected. The issue repeated today. Same steps to remedy the issue.

Where should I start looking to permanently resolve this? My wi-fi is a source of pride. Combined with DD-WRT, my router has been online for as long as 500 days without any issues. Only after upgrading to iOS6 did anything weird begin to occur.

So, where can I start troubleshooting? Thanks!

Try using AES instead of TKIP and see if that helps any. If it is an option, try WPA/WPA2 Personal Auto or Mixed mode.

Trying AES instead of TKIP.

Here are the wireless modes I have:

Disabled
WPA Personal
WPA Enterprise
WPA2 Personal
WPA2 Enterprise
WPA2 Personal Mixed
WPA2 Enterprise Mixed
RADIUS
WEP

I would set it for WPA2 Personal Mixed. Try AES instead of TKIP. If Auto is a choice, use it instead of selecting TKIP or AES.

The router has been set to the AES algorithm for almost two days now. No loss of connection on our phones, so I'm going to leave the mode alone for now.

Thanks for the help.

TKIP is most often a software update, while AES is all done in the hardware, from what I have read on many device driver specs. So, it leaves the CPU and software to focus on other things, while improving security to boot. I keep mine set to AES-only. I have a gaming bridge and a switch where I plug in all the game consoles, including systems that don't support AES, even some that do(better speed using dual band N(think X264 MKV files on the PS3 using DLNA from a server across the house)), and ones that do not support wireless period. This shows you can adapt any hardware that has an ethernet port. More cost effective and leaves the router managing less wireless links to use the switch between them(and an AP to offload clients that would have weak signal in that part of the house with no messy wiring). Pretty much all modern PC hardware, phones, tablets, and game consoles support it though. Gaming bridge is a handy option for devices without an OS to load appropriate wireless drivers or without a way to upgrade the hardware.

A fool thinks they know everything.

A wise person knows enough to know they couldn't possibly know everything.

There are zealots for every OS, like every religion. They do not represent the majority of users for either.

I started having issues with my MAC white list and saving AES as the WPA algorithm. Might have been me doing something wrong, but I figured now was a good time to upgrade dd-wrt. So I did that last night. Now running v24-sp1 std.

AES is now there as it should be. I also managed to create a virtual guest wi-fi interface using a different (and easier) password than the regular wi-fi.
