    Alright, so this is confusing the heck out of me on the reason behind this.
    I'm trying to setup in the network one have Wireless N with full Turbo mode so those with N can use the full power and speed if it can be supported and a separate network to use Wireless G with afterburner/turbo for those that support it. The problem?
    In one laptop, it is an atheros-based wireless card of a sony vaio. It can handle Wireless N. When I set the wireless N only router to N only, the laptop can't seem to connect. However, if I switch it back to Wireless G/N mix, the laptop will connect just fine under N signal. The laptop has all the updates it can possibly have including the wifi adapter. Is something up here?
    This wireless N router setup is using DD-WRT on a FR-300rtr.

    The Other router that is set for Wireless G, my laptop that has the afterburner/125 High speed mode doesn't seem to connect using that mode. I checked my laptop and I think its because since my laptop is old (HP 2005cu) and I have Windows 7 installed onto it, the driver itself doesn't seem to have an option for Afterburner/125 High Speed mode. I let Windows find and install a driver since the only driver on HP's site would go to XP for the card and I heard even if I find a Vista version of the driver that Vista driver and Win 7 usually don't like to play well with each other. I would assume I'm correct on this part?
    The Router there is a Wireless G router using Tomato RAF on a Buffalo WHR-HP-G54.

    That router is just a rebranded Dlink 615.

    You may have better luck with Openwrt on it.

    ya, a rebranded Dlink 615e1 if I recall from the DD-WRT. I figured its better to mention the FR-300rtr over a dlink 615e1 since that is what it was before I flashed it back out of that.
    And I admit though, I'm intimidated by Openwrt since I first saw it long ago since it seems that unless you get a specific version with a GUI, it is usually all telnet command operations. I'm not that proficient with command interfaces like that and would want to get to the point in a few seconds instead of trying to remember what commands I need to type and files to edit.

    Just a thought, is it possible that the Sony laptop is looking for N in the GHz range? Doubtful, just a thought.

    What do you mean? I figure it should look for the 2.4GHz fine since I don't think that router has any possibility for a 5GHz range.

    No, but does the card in the laptop have 5GHz capabilities? Perhaps it defaults to that?

    dlink dir-615 + dd-wrt = crappy wifi :) stick with stock firmware or build yourself a pfsense box.
