WRV54G Limited Cable Modem Speed?

    I am an Insight customer and they recently upgraded me to 10Mbps download speeds. I am still only seeing about 1Mbps speeds on various internet speed tests and through Insights internal speed test. If I directly connect my computer to the cable modem I am getting 9+Mbps speeds. I am connected directly to the WRV54G and have tried various MTU settings to no avail. I have noticed that if I disable Wireless on the router, my speeds do dramatically increase on my computer that is directly connected via the router. I would like to leave wireless enabled for my laptop obviously. It almost seems as though having Wireless enabled autonegotiates my lan port speeds way down. I have tried setting my NIC at Auto or 100/Full and it makes no difference. I bought this router just a few months ago and am very frustrated that it seems to be limiting my cable modem speeds. Any advice as to what to check? Do I have a dud or is this a known issue with the WRV54G? I have the latest firmware from linksys.com. Thank you.

    for starters, I think you are identifying your hardware incorrectly. I think you have a WRT54G, not a WRV, as the WRVs are VPN endpoints. As for your drop in speed when you enable wireless, are you sure that you dont have someone else mooching off your wireless connection and sucking the bandwidth dry for your internet line? That's the only thing I see. If you do not have any security enabled on your wireless network, I advise that you enable the strongest wireless security your laptop supports.

    It's definitely a WRV45G, it is a multipurpose device. It serves both as an internet gateway, firewall router, and as a VPN device. I also can guarantee no one is mooching off my bandwidth. I have WEP enabled with a 128-bit key as well as MAC address filtering to only the MAC address of my wireless NIC on my laptop. Please don't treat me like I am a beginner here.

    Here is the product quote from Linksys in case you still don't believe me about the model #:

    "An Internet connection-sharing Router, Switch, and Access Point with built-in VPN endpoint capability and advanced security features"

    my sincerest apologies...and beyond that, I have no clue then.

    for cable you should be using an MTU value of 1500, and make sure you set this manually. check you are using a good Ethernet cable as well from the Cablemodem to the WRV54G and from the WRV54G to the PC

    I have my MTU manually set at 1500 in the Linksys configuration page. Doesn't seem to make any difference. I had already tried different ethernet cables. Also, no difference. I am about to just go buy a new router to test and I can always return it if it doesn't fix the problem. I am frustrated beyond all belief.

    only other thing i could suggest is to try resetting the router back to factory defaults or upgrading to the latest firmware if you have not done so already.

    The diagnostics for the Insight Speed Test say the following when I am connected via the router:

    The theoretical network limit is 277.04 Mbps
    The NDT server has a 2048.0 KByte buffer which limits the throughput to 397.95 Mbps
    Your PC/Workstation has a 1953.0 KByte buffer which limits the throughput to 379.55 Mbps
    The network based flow control limits the throughput to 2.77 Mbps

    I've tried various settings of flow control on my NIC. I can't find any flow control on the router. Does this spark any ideas? The 2.77Mbps is pretty similar to the 1 - 2.5 Mbps I get reported during the test.

    Yes, I had already upgraded to latest firmware and tried factory settings. Thanks for your help. It sure seems like Linksys is throttling my Lan port speed down to like 2Mbps and I can not figure out how to tell it otherwise.

    What site are you going to to conduct your speed tests?

    Well I've been using several. I have been basing my tests off of Insight's internal speed test that simply goes from my home to the central office (http://sp1.insightbb.com). It displays 9+Mbps when plugged in direct to the cable modem but only 1-2Mbps when going through my router.

    I actually bit the bullet tonight and purchased a Netgear WGT624. I figured I'd bring it home and if it had the same problem I would simply return it. After 3 minutes of setup, I am connected through my new router and getting 9.7Mbps!

    I guess Netgear just won my business. Its nice of Cisco/Linksys to throttle my bandwidth....$100 down the drain.

    Linksys isn't throttling your bandwidth. Why would they do that?
    I can't help much except that maybe you have a bad router or a bad config setting. I have the same router on cable and it runs a WPA wireless plus a VPN 24/7. I get full speed always.
    There are things I don't like about the firmware right now but so far it is doing everything without a problem.

    What firmware are you running? You still haven't indicated that.

    I am not sure which firmware I was running, but after I started noticing all this, I updated to the latest firmware (2.39.2) a few days ago and it did not get any better. I have reset to factory settings several times, so either A.) I have a bad router, or B.) Its limiting me down to 1-2Mbps. Extremely frustrating since I bought it 5 months ago for $110 and no longer have the box. I just figured my crappy speeds were due to my cable service. I might still see if I can exchange for a new one.
