Not getting full speed on pc with 802.11n

[redman4264]

I have a 50M cable connection for a couple weeks now. They gave me a motorola-9F594 modem to use until I could get my phone service connected with cable also.. With the motorola modem my 2 pc's with 802.11n adapters were maxing at just at 50M on speed tests and my other pc with 802.11g was getting around 23M..

Well they came out and put in a arris TG852G modem to get my phone hooked up, now I can only get 23M with any pc wireless? I have tried many different setting in the modem.. Seems if I allow it to be able to connect back to a 802.11b I will only get 802.11b speeds on any pc. I have it set now to allow g/n and manage 23m which i understand is about what a 802.11g will handle.. If I set it to n only then I can get the full 50 but cannot connect my other pc.. I know one solution would be to buy a 802.11n card for the laptop but I should not have to go this route.

I have searched alot about this and cannot seem to find any solution that will allow me to have g/n connected and get max speed on the n side. I only have to neighbors on wireless and they are on channel 6 and 11, so I am set to channel 1. My wireless mode is set to G/N mixed, and QOS is not on (called WMM in my modem?). All pc's have great signal also. now to my question..

Is there a setting I am missing somewhere or have overlooked in my modem?

That new modem must not be able to run the two networks separately. Some will run everything on the speed of the slowest device on it.

Just like to add that both pc's are only connected at 54Mbps even though I have 802.11n enabled on both adapters. Nothing has changed with them since the motorola modem and they were both getting full speed there.

That could be the problem, I will need to see if ISP will provide a modem that will connect to both then since I am renting it from them.
