WRT54G speed trouble

    Hi, I am new here and I have a little problem with my Linksys WRT54G router. I can connect to internet but I can't connect to the File server my ISP is offering to me, at least not at the speed I should get. I should be able to connect to their server with 54 Mbps (as this is 54Mbps router not 100 Mbps) but I can only connect with the same speed as my internet is going. I had the wired Linksys befsr41 and since I had trouble with it I changed it with the wireless one. In the meantime I had been connected to internet directly to my lan card on the PC and I had the full 100 Mbps speed. Now My ISP is telling me that this router of mine (wrt54g) can't be set to work with the range of IP addresses they have on their server and that's why I can't connect to full speed. Is it true? Thay said that with another brand, like ASUS (wired router not a wireless one) I won't have that problem. Is there another solution to make my router work? Thay told me to try putting a switch before the router and connect it to second lan adapter but I couldn't make it work. Can anyone help me? Thanks.

    Let's clear up a few things.

    1. Connected speed does not equate to bandwidth or data transfer speed (not dissimilar to dial-up connection), e.g., you can connect at a 802.11g standard 54Mbps, but your max data throughput is about 20-25Mbps. Simply connecting to the modem at 100Mbps using a LAN cable does not equate to 100Mbps ISP data throughput, there is at the least network overhead to contend with, which shaves performance off the max - the less efficient the network connection the slower the transfer speed.
    2. Connected speed to the router (whether at 100Mbps for wired or 54Mbps for standard 802.11g wireless) refers only to the connection between your router and computer, and not the broadband speed to your ISP.
    3. Most ISPs offer much lower bandwidths to users that that of a wired or wireless connection - the bottleneck is at your ISP connection, so your router should be more than capable of achieving your ISP's max speed. Some Asian residents (e.g., Japan, Hongkong) excepted since some of them are on high speed fibre optics connections - we are speaking of 30Mbps+ throughputs.
    4. If you are accessing a FTP server, you may need to enable Passive mode on your FTP client to bypass issues with accessing such servers behind a firewall.
    5. Any wireless or radio technology is susceptible to environmental variables such as radio interference (or jamming), degradation over distance (root mean squared), signal absorption or blockage by materials (some group this into interference), so wireless networking is no exception, and no connection is immune.

    However, without knowing your wireless network setup and layout and what speed your ISP is offering you, it is not possible to comment individually. Please provide more information about your ISP and network setup.

    Hi, first of all thank you for your quick responce and I am sorry for doubled post. I tried to delete the last but I couldn't. As for my router, I need to say that I don't have problems with the broadband speed. I am connected on 128 kbps and that's what I get. The problem is with the speed to their file server. They have a "FREE File Web Server" and it is on LAN level. Every user they have can connect to this server on 100 Mbit speed. I have had connected to their server at that speed when I wasn't using a router, directly to my Lan card. But, since I have two computers connected, I wanted to connect to internet through a router. Now, I can still connect to their file sharing server but only at the speed of my internet connection - 128kbps. So without the router I have been downloading at great speed of about 30-40 mbps and with the router the speed is around 100 kbps. For example a file of 700Mb (divx movie) I could download for about 5-6 minutes, and with the router it takes 4-5 hours. My question is: can this be due to the settings of the router and can it be fixed (set properly) or it cannot be done at all.
    Thank you.

    I really don't see how you could have ever seen LAN speed over a 128K connection no matter how you connected. I suggest you try your speeds again while directly connected and you should see the same speed as when connected via a router. The router will have no trouble keeping up with a 128K line.

    You should post details of what kind of line this is. DSL/Cable "Lite"? Some kind of proprietary accelerator?

    I would have to agree that this seems a little fishy. For the most part, Linksys router's can't route network traffic through much faster than 10-20mbits, but to only get 128k through, that isn't right. A great deal of ISPs do MAC filtering to try to keep only one computer accessing the net. The crutty speeds may be the result of a defense mechanism from the MAC the ISP's seeing being different now.

    I agree. Logically, it is not possible to achieve a LAN connection over a broadband connection since the only LAN you have is between your router and computer - the speed limit to the outside world is the broadband connection.

    mihaildz, have you got 2 connections out? I.e. one for the internet and another one to this "FREE File Web Server"?

    You mention that you previously connected "directly to my Lan card". If one side of the cable plugged directly into your LAN card, what did the other end of this cable plug into?

    Did you access the internet as well as this file server through this LAN card connection?
