Linksys E2500 (LAN Download Speed Issues)

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 / Netcomm & Dlink 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 a 72BPS whereas on the Netcomm / Dlink it used to be 130mbps. Not that this bothers me, however the file transfer speed matches the Link status 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 which has a wired connection 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. 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.

  Is there any settings in the advanced Wireless mode for the Linksys that can make my internal file transfers faster.

Any help is highly appreciated.

Re: Linksys E2500 (LAN Download Speed Issues)

You can try the following combination of settings:-

 

A] With the help of Cisco Connect Software (if at all you have installed the router with the help of this software)

          1] Open the software and go to the option which says "Router Settings"

          2] Then click on the option which says "Advanced Settings" which will take you to the router's configuration page.

         3] Then go to the Wireless tab, keep network mode as mixed, and make Channel Width to 20 MHz only and Channel to 6, 9, 11..

         4] Then click on Security tab disable SPI Firewall Protection, uncheck Filter Anonymous Internet Requests...

 

B] If you haven't installed Cisco Connect then you can log on to the router's user interface using its default IP address in the browser which is 192.168.1.1 and type in 'admin' as the password leaving the user name field blank? This will take you to the router's web interface and then follow steps as mentioned above to make the changes.

 

Then check the connectivity status…

Re: Linksys E2500 (LAN Download Speed Issues)

First of all a thank you for your reply....

Made all those changes with no luck at all. Still at 72MBPS.

 

Had even changed my router to use DD-WRT firmware. Link speed came up as 150MBPS. File transfers were still at 40MBPS. The firmware was a bit non responsive so flashed it back to the linksys firmware which is working well thought not as fast as i would ideally like it to be....

 

Still not a happy Jan...

Re: Linksys E2500 (LAN Download Speed Issues)

Bought a AE2500 USB adapter and now am finally happy.

Data transfer is at 11MB/s or around 90MBPS which is to a PC connected through a 10/100 MBPS port on the router.

So pretty much theoretical max bandwidth on a 100MBPS port.

It seems to be like installing the latest adapter (AE2500) in the computer increased the speed of the computer. So, right now its providing the better throughput.
