Hi
I did some testing with a few wireless N routers and then decided to buy a Linksys e 2500 as it was on a special for $66 in Australia.
The wireless routers i tested were (Belkin brand new model / All Used ones)
1. Netcomm N800n Fastest wireless transfer speed 9MBytes or 72 MBPS.
2. Dlink - Around 6MBytes/s or 48MBPS.
3. Belkin - Around 4-5 MBytes/sec
Did not test the Linksys before buying it.
4. Linksys E 2500 - around 5MBytes/s = 40MBPS.
After all this testing, got a new Linksys believing that a cisco device should have good quality.
My problems is that the connection speed on the device stays at 65MBPS whereas on the Netcomm / Dlink it used to be 130mbps. Not that this bothers me, however the file transfer speed matches the connection speed.
The router was placed at exactly the same location, file transfer was checked by transferring large file sizes.
Lan setup is
1. Belkin ADSL 2+ (Modem with Wireless b/g and Voip) only being used now as an ADSL Modem and VOIP service.
2. Cisco linksys e 2500.
3. Media centre PC wired connected to linksys e 2500.
4. Main PC (Connected wirelessly to the linksys). The network adapter is a DLINK DWA125 N150 adapter (2.4GHZ only). The distance between the wireless adapter and the wireless router is approximately 12 feet and there is direct line of sight.
5. IPAD.
5. Using 2.4GHZ as i dont have a 5GHZ adapter yet. Router is only on wireless N mode.
I was better off using a second hand Netcomm rather than a brand new Cisco router. The cisco router has 4 internal antennas, whereas the netcomm one had only 2 external antennas. This frustrates me to no end. I have not used the WRT firmware yet.My signal strength is excellent. Only problem is the slow internal transfer between the Main PC and the Media Centre PC. Main PC is Core i7 950 where as the Media Centre is a Core 2 Duo e6400GHZ with 4GB Ram. Both PCs running Windows 7 Ultimate (Main PC) , Professional (Media Centre PC).
My network knowledge is decent (UC Engineer - CCNP (R+S) + CCNA voice)
Q1. Is there any settings in the advanced Wireless mode for the Linksys that can make my internal file transfers faster.
Q2. Will changing the antenna strength lead to a faster internal file transfer speed? Changing from the default of 28 to higher?

Q3. Once i have the DD firmware, if required can i go back to Linksys firmware(?)

If you're unable to achieve satisfactory performance, please list all of this information in a forum thread:

That is not encryption, that is Authorisation type.
Which crypto did you use?
Bonded channels requires either no crypto or AES, nothing else. _________________ Kernel panic: Aiee, killing interrupt handler!
This is btw not the right place for a poll on stock firmware performance, that belongs in Cisco's forums.
Read the threads here instead about user experience on the router when running dd-wrt firmware. _________________ Kernel panic: Aiee, killing interrupt handler!
The Cisco modem only shows the wireless security as WPA2 Personal or Enterprise...
The reason i posted in this forum was to get feedback from people who had upgraded from Cisco to the DD-WRT firmware..
Guess i will have to flash it myself and then test!
I have seen this problem before a couple of times..
First, check wireless settings and check 20/mhz channel first.. then you can experiment 40mhz channel.. You are using an atheros wifi card in your laptop and changing settings on the router that this device supports will affect performance... Such as advance wireless settings, afterburner, bluetooth co-existance mode, wireless channel selection, transmit/receive antenna. and mode... if you dont have any B clients you can change the mode to G/N mixed and nix out the b stuff.
On my E2500 wireless I have posted screenshots before I connect at 270/300mb/s link speed, and I have 100/100 mb internet I can get almost 70mb down and 25/30 up with a normal laptop with intel card and windows 7.
