In Eastern WA I had Fiber Optic so my internet went straight into the router and I would get a 300 Mbps connection. Moving back to Western WA I had to get cable so my router is connected to a cable modem. Motorola SURFboard SB6121. Now I can only manage a 130 Mbps connection wirelessly to my laptop.

assuming its the very same router, sounds like you are being hit with "good neighbor" issue... My SB6120 has no impact on the router's LAN wireless speeds

"Good Neighbor" Issue?
-
Part of the .11N Wireless standard was that if you had a .11N router, and your "neighbor" also has a router, your router will drop itself down from maximum wireless speeds so as not to co-opt the wireless bands in your immediate vicinity....
The .11N standard says you have to have 2 wireless channels in order to get the 300 Mbps that .11N offers (in theory).
Since you are seeing only about 1/2 the maximum speeds, that is why I am thinking its a good-neighbor issue...
In the router setups for Wireless, it has an item that says "Channel Width" = Auto 20/40 or 20.... I think your router is using the Auto setting and dropping you down to 20 instead of 40, as needed to reach the 300 Mbps level....
You might try to change your wireless channels to say 3 (primary) & 7 (secondary) as they seem to be lesser used...which is what I did here....
-
Download inSSIDer (http://www.metageek.net/products/inssider/) and you can find out what channels your neighbors are using then choose channels for yourself that are less used or not used at all.
-
Hate to be the one that asks the stupid question, but what are you using to test the connection? I assume your talking about LAN to LAN right?
-
I actually used an app on my phone that shows all the nearby active wireless channels and ended up changing my channel a few weeks ago already. I just started it up, and the person who was using the same channel as me, changed theirs to channel 1, I'm still on channel 11. There are a few other wireless signals but they're all using 1 or 6.
To find my wireless strength (on Windows 7), I right clicked on my connection , then Open Network and Sharing Center. Then click on my wirless and it tells me what speed I'm connected at.
-
Just connected to my network again, and I'm getting 300 now. I think that other connection that changed might have been having issues too and changed their channel.
-
And this morning I'm back down to 130, but there is no one competing with me on the same channel. I don't get it?
-
Curious, What wireless mode is the router currently set for?
What other WiFi devices do you have and are near by?
Is Short GI and WMM enabled?
-
Check in the router wireless status and
see if it shows a .11N connection for
that device....
-
My laptop wireless, I have the option of B only, G only or B/G/N (which is what is selected).
My router I have it set to N only. But I have tried switching between that and B/G/N and it doesn't seem to make much of a difference.
Roku in my bedroom (I'm in a 1 bedroom apartment), and my Android phone (currently near my laptop).
Yes, both Short GI and WMM are enabled.
All three devices (laptop, phone, roku) say there are all in .11n mode. And it looks like it's not just my laptop that's at 130 either.
-
Try testing with Short GI and WMM disabled...
-
Tried that and no change. :(
-
Might have someone review your router settings via teamviewer.com to help you out.
-
Well, if anyone is willing we can try that route.
-
FurryNutz helped me out! Thanks again :)
-
Let us know how it all works out.
Mode was set on G/N, changed to N only and disabled WMM and Short GI.
Has other N routers near by. ::)
-
Yah, tons of others. :) I lowered the transmit/output power to low but it cut my speed back down. Have it at medium right now and seems to be working out well.
-
Ok give that a go and see how it works. Ya, just a lot of there routers around and will probably have to deal with some interferences.

I'm havng a similar problem. The wireless system (Dell Inspiron 8000 running WinXP) on my network connects at 130 consistently. However, if I reboot the router while that system is connected, it will come back up at 270. Rebooting the router daily is the only way I can obtain the higher speed connection. It used to connect at 270 when the computer booted, but no longer. The only change is that I had to move the network card to the second PCMCIA slot to allow the addition of an external USB 2.0 card to support an external backup drive as the old Dell doesn't have USB 2.0 built in.
-
Try setting the WiFi mode to Single mode N only. This will get you back to 270Mb connection however be aware that if you have other devices that don't support N, You'll need to set for G and N mode.
let us know.

I got the exactly same problem.. How to do this?
I cant find where to disable WMM and Short GI?
-
Change wireless modes and settings under Setup/Wireless/Manual.
Short GI and WMM can be found under Advanced/Advanced Wireless.
Let us know how it goes.
