I am a bit of a hack when it comes to network setup, so please forgive me if this is something basic. I did read the announcements and searched a bit, finding one similar post but with no answer.
I just got Road Runner Extreme 30 Mb Down, 5 Up.
When connected directly to the Time Warner provided router I get 30 down and 4.5 up.
When connected to my Linksys WRT54G/GL/GS router via wireless I am getting just 17 down.
Any idea why I am losing 13? Pretty vanilla setup, nothing else taking load and great reception to the wireless on the test machine.
As an FYI, I have my network setup like this:
1. Cable wire into RR provided router.
2. Cat5 cable from RR router to my Linksys WRT54G/GL/GS.
3. Laptop via wireless to Linksys WRT54G/GL/GS.
I am using DD-WRT v24-sp2 (10/10/09) std - build 13064. Any help would be appreciated.
1. Wireless on a g machine will give you a throughput of 20 at the MOST.
2. You haven't read the announcements at the top of this forum. _________________ I fix "shortcuts". If you don't have time to read thoroughly, I don't have time to re-type what you missed.
I did in fact read, and just looked over them again for something that either:
a. Gave me the answer you just gave me.
b. Gave me some rule that I violated.
Maybe I didn't catch something I should have, but I did in fact take the time to try and answer my question on my own.
If I violated some expectation, please let me know which one(s).
In spite of that, thanks for the answer. As I said, I am at best a network hack. Had no idea of that limitation.

Build 13064 has many issues, try a recommended build from the announcements thread. _________________ Asus RT-N16 [Build King Kong 18050M NEWD-2 K2.6 + Optware + My Page]

Download speeds over wifi will be limited using 802.11G Wireless hardware. Not much you can do. You can try the following to see if it speed up slightly. Set Wireless network mode to G mode only and set Wi-Fi security to WPA2 Personal and AES encryption. Also update the Wi-Fi drivers of you client devices. _________________ Asus RT-N16 [Build King Kong 18050M NEWD-2 K2.6 + Optware + My Page]

17MB is plenty, and if I need the extra 13 I'll wire it up.
Plus the router still has the 30MB to pull from so if my logic is correct I'll have two devices that could, theoretically pull down 15MB each over wireless and my internet connect would be able to handle it.
Is the initial note still accurate that the most I can expect is 20Mb down over wireless?
Yes, G spec will always be G spec and limited to ~20mbps throughput. The advertised rates are the raw link rate that doesn't account for overhead. If you want more throughput you need N spec equipment on both ends (AP+client). _________________ Read the forum announcements thoroughly! Be cautious if you're inexperienced.
Available for paid consulting. (Don't PM about complicated setups otherwise)
Looking for bricks and spare routers to expand my collection. (not interested in G spec models)
I've gotten 25 Mbits down on a wireless connection before using A WRT54G-TM as the AP and a WRT54GL as the Client Bridge. The thing that matter the most is obvisously the SNR Margin or connection quality. A SNR Margin over 40 will give you the full 54 Mbps link.
Here is a link to give you an idea of SNR Margins.

No! Example: you get 20Mbits over wireless
1. device 20Mbits solo
2. device 20Mbits also solo
1. + 2. device active at the same time. 10 Mbits device 1 and 10 Mbits device 2
Thats a very static example but you get the idea behind it (i hope)
So as said 802.11n Wireless hardware (300Mbit/s) and most likely you get the "missing" 13Mbit/s

Or, you still have 13Mb dedicated to wired devices, if you prefer to think of it that way _________________ __________________________
