Subject: Re: [Bluez-devel] Same = Old Speed Issues

Hello Guys,

&= nbsp;

I've been playing around with this again today, looking into AL= C MTU's and things like that but really can't find any resources to suggest= why I might be getting such poor speeds, I thought it would be a plug-and-= play kinds of affair.

&= nbsp;

I also made an effort to try a couple of other kernel versions,= just in case, but they all gave the same results as 2.6.23.<= /FONT>

&= nbsp;

Thanks for any further advice guys. Is it worth me giving you s= ome HCI_DUMP information? Is that likely to hold any clues as to what's goi= ng wrong?

&= nbsp;

Cheers,

&= nbsp;

Rob
