Default Curve 8320: Interference From iPod Touch w/WiFi

Please Login to Remove!

I'm using a Linksys WRT54g with DD-WRT firmware connected as the wireless part of my network (UMA doesn't work with my FIOS ActionTec, that's why the Linksys). All is well with WiFi/UMA on the BlackBerry. Well, until I enabled WiFi on my new iPod Touch. I received a call, and couldn't hear anything but static. Likewise when I made an outgoing call. I'm thinking QOS settings might help this, but I'm at a loss as to where to start with the parameters. Any suggestions would be much appreciated. Thanks!

What I've done is set my Linksys to high priority on the Actiontec. Then I have my laptops or other wifi devices connect to the Actiontec. The only thing connecting over wifi to my Linksys (WRT54GS) running dd-wrt is the 8320.

In the Linksys, I've set the 8320 to high priority, although I also have my desktop and Playstation3 set to the same priority.

I'll double check my router settings and post again. There is a way to improve things on the Actiontec as well. I can call on UMA with that, but it's not reliable, or at least wasn't when I was running OS 4.2.2.184.

Thanks for the quick reply and info. I had opted to go with all of my wireless stuff through the Linksys (your plan is probably better), so I did set up priority on ports 500 and 4500 for UDP. So far, so good. Time will tell.

First, these are just the settings I have. Some of them may or may not even matter for performance. It's just where I ended up by messing around.

My starting point nearly a year ago was this BB FAQ, plus another that I can't seem to find:

Linksys Router Tips - BlackBerryFAQ

I'll post pics, but since those go away over time, here's where the settings are.

For the Actiontec, go to the Advanced tab, the on the left is the QOS link. In the traffic priority screen, you can add new priorities. Under All Devices I have the Linksys, my desktop, and my VOIP box set to priority 6. Under wireless I have the Curve set to 6 as well.

Why everything at priority 6? No reason, pick whatever you want. I tried different priorities and the desktop would stutter on file downloads. So I bumped it to 6 and no degradation in call quality that I can tell.

I just literally noticed that there's an Input Rules and Output Rules section. I thought it was all the same stuff, so I was only really prioritizing Input. I've added the same things to Output as well, which might actually enable me to use this router instead of the Linksys full time.

On the Linksys, under the NAT/QOS tab I have the MAC Priority for the Curve set to Premium. This is dd-wrt v .24. Others are similar as far as I remember.

Also on the Linksys, under the Wireless>Advanced Settings tab are the settings where the BB FAQ comes into play. One big thing is to Enable the WMM Support. That's something I got from another FAQ. It prioritizes VOIP, streaming video, etc.

Some folks increase the TX Power as well. My place is small so I just stick with the default. Also you can see I ignored the Fragmentation Threshold and RTS Threshold figures from the FAQ. Those seemed to make things worse way back, but I updated them after I took the screen shot. Just to see if it makes any difference.

I've never been able to figure out port forwarding and those types of settings. I can find info on how to set it, but only for a specific port, and I think the UMA settings are to a range, rather than a specific address. I don't even know if what I just said makes sense, but that's my understanding. I've just given up on those other than I did add some UDP priority somewhere.

My reasoning on setting the other wifi stuff to the Actiontec is that I've prioritized the things I need to, so anything connecting on the Actiontec wifi has to wait in line. Doesn't seem to affect laptop performance.

The port setups are for a range, but I used a range of 500 to 500 for one port, and 4500 to 4500 for the other. Both show as separate entries, and both are set to "premium" (I believe). In any case: Come on man. You figured out all of the other stuff you did. You can certainly figure out the port thing.

Cool. Makes sense. And again, thanks for taking the time to provide so much detail. Since I seem to be working fine now, I'm not gonna mess with success, but I'll refer back to your info if I need to.
