Router speed drop solved2006-01-22 (updated: 2014-08-17) by MrFlimpyTags: router, speed, WGR614, BEFCMU10, cable modem, electric noise, throughput I've been lurking here for a while trying to solve my speed problem. Thanks to everyone for all the great tips, but I had to laugh when I finally figured this one out. Maybe someone else can use the tip: I just got upgraded to Comcast 6Mbs, but was only getting throughputs in the 2-3Mbs range, with an occasional 4.5Mbs, and an occasional 1Mbs. Really frustrating. I tried all the tweaks here. TCPOptimizer is an awesome little program, and seemed to make some marginal, but inconsistent improvement. I got rid of ZoneAlarm since v5 seemed to cause a problem even though I had v6. No software firewall, and new software firewall: same problem. No antivirus software, and new AV software: same problem. I have a Linksys BEFCMU10 (the original version) cable modem, and my main router is a Netgear WGR614 v1 wireless router. The wireless is turned on and used, but not for this connection. All the connections are wired Ethernet. Lot's of posters here have newer versions of those things, but my same problem. I considered buying new equipment, but it turns out that even this old stuff works perfectly, as you will see. Going straight from the modem, I get full 6Mbs+. Through the router, it drops by half or more. During testing, I was cycling things on and off, switching the wiring when I finally stumbled on the problem. I was connected directly through the modem, but had the router turned on, and my speed dropped by half! I figured I had the wiring wrong or something, but nope, no part of my system was connect to the router. I have a homemade wood rack, and the router sits just above the modem. I could do a Speakeasy test wired through the modem getting 6Mbs, and watch the speed drop as I powered up the router. So, the problem is: electrical noise! All the cables are shielded, and the power cords are segregated from the data cables, so the noise is coming directly from the devices. And low and behold, when I separated the router and modem by a few slots on my rack, I'm getting full speed minus about 10%, which is probably reasonable for router overhead and marginal residual noise. I imagine a lot of you out there have your router sitting on top of or below your modem. It's a stupidly simple solution (although it took me a week to stumble on it): if your having line speed problems, try separating your router and modem. Hope this tip helps someone out there. And thanks for everyone else's help.

With the router and modem sitting next to each other, my download speed was 0.4 to 1.2. Connected directly to the modem, 17 to 22. Moved the router about 4 feet away from the modem, and now I'm getting 14 to 17.
simple fix which completely solved the problem. thanks!
Totally worked for me. Genius!
THANKYOU!
I was almost ready to kill myself getting about 50 kb/s (yes, that is kilobits, slower than a phone modem) with my gadgets sitting about 3 inches apart on a shelf. I moved them 10 feet apart, and suddenly I get my full 8 Mbit/s, which is actually more than I got connecting my computer directly to the DSL-modem. Considering I'm being treated for depression the thought of killing myself over this was very real, so in essence you saved my life. Again, thankyou!
Hmm, they are now 1,25 metres apart, but the speed didn't raise yet. Do I have to increase the distance or is it just not working for me?
So simple and yet so effective. This is how all fixes should be. Had about 6 hours of irrelevant mindblowing tech disdussios with my ISP about this issue. Will now phone them and give them a big raspberry. Thanks man
Thank you for this article. Came up on a google search and solved my problem. :)
I just tried this and it took my sub 1mbps connection back to a 10mbps where it should be.
haha thank you so much
Some simple fix .
And it worked perfect
That is a smexy suggestion, just tried it and it worked!
Awesome Advise. Worked perfect. Thanks for the IDEA. This IDEA changed the life of many.
Thanks man, you article saved my day, great post!!!
It was driving me totally batty! I was going to go drop $$ on a new router. Saw this article, and fixed it right up. Thanks! You rock!
Thanks it worked!
After seeing this thread, I will be asking TWC for a refund for service I have not been getting.
I've had speed problems ever since upgrading to turbo. My 2 y/o modem that TWC never mentioned should have been replaced has always sat on top of my Netgear 3800 wireless router. TWC never said anything about the proximity of the modem to the router. After a bunch of server time outs, a TWC tech installed an Ambit Docsis 2.0 modem (6 y/o technology) a month ago and put it where the old one was, right on top of my router. The speed got even worse. On 10-5, I decided to connect the modem direct to the laptop and used Speedtest.Net to find that the speeds were 5 times faster (20 mbps) without the router connected. After doing a Google search and finding this thread, I moved the modem 1.5 feet away from the router and reconnected the Ambit modem to the router. That resulted in speeds that were as fast as without the router connected, 20mbps. After fighting with TWC for so long any way due to their older technology and the $6.00/mo lease price, I had already ordered a Zoom 5341J Docsis 3.0 modem. That has since been installed and resulted in an additional 1.5mbps speed increase. AND it is sitting on top of my Netgear 3800 router without any sign of speed degradation. The warning to ALL, watch out for any cable company's leased equipment. It may not be the latest technology and may cause interference with your newer technology devices.
WOW.
Have a new ASUS RT-N66U and a Belkin N-750. Both were only giving me a 1MB download while wired to the router instead of the 16 MB i should be getting. Read your article and moved the router away from the Modem/phone adapter and tried to separate the power cords a bit better and it did the trick. I guess the new routers do not have the shielding that the older routers did. I could hook my old Linksys WRT54G up in place and it was fine. Thank you!!!! Dave
for the past week my download speed would drop to 3mb or less than 1mb, made me frustrated because my internet plan is 100mb down and 12mb up. Only fix I knew was repeatedly resetting or power cycling modem and router. I did that for almost a week, missed work some nights over it. Then I tried this thread's suggestion and VOILA, speeds back to normal. Thank you, OP!
I can't believe it!
I tried everything, looking for where I was losing speed. When connected directly to my modem, I would get exactly the 20mb down and 10mb upload that I am supposed to. But when connected to the router, whether wireless or wired, I would get 13mb down and 6mb up. After separating the modem and router, I am getting exactly what I am gettign when connected directly. I still can't believe it! Thanks!
Thanks so much 100% improvement
I'm an I.T. pro, at least on paper. I've called my ISP given them hell over slow speeds. I actually ran a wire and connected via Ethernet to my work computer with everything else, about 5 other item, on wireless in the house. I never noticed all the wires next to the modem, I just wanted to have a faster wired connection for work. Well as soon as I moved the router and decided to work wireless on my work computer, I mean the router in a different room away from the wires, the speed goes a blazing. Can't believe I missed that. Back in my tech support days that was my number 1 recommend to users and here I was making the same mistake. The router should be as far away from electrical and other peripheral wiring as possible unless they are shielded, which is unlikely.
Un-f'n-believable that this is an issue. But, it totally worked. Thanks!
Thanks for the tip, I will try this. I have been having soo much trouble with my speed tests. I am paying for 34-72 for the download and 3 for upload. But when I perform a speed test, my download comes up 4.5 and my upload comes out to be 1.5 or less. I have been paying for speeds that I'm not getting at all. But thank you for this tip, I will try and see if separating my modem and router will make a difference. Also I will try just shutting my router off.
