Speed drops by 50% with WNDR3800 wireless

Just had SureWest 30Mbps service installed and tech assured me all his installations test at 29+ Mbps. Got everything fire up (the supplied the Netgear WNDR3800 Router) and speed was about 17Mbps Down and surprising, just a touch faster Up. He was quite surprised, so we hooked several computers to the router directly with Ethernet and they all tested 29+ Up and Down. We again tried several computers Windows 8 Laptop, MacBook Pro, iPhone 5 and they all were about 50% lower using wireless. We even tried hooking up a Linksys router with the same result. I have unplugged all wireless devices (alarm, cordless phones, etc.) but it makes no difference. We also don't get much range. Obviously something is interfering, but this is a dramatic difference. A further complication is SureWest won't provide the router password to allow me to check settings. Any ideas on what to do?

What is the connection speed as reported by the OS? Make sure you are using WPA2-AES encryption. Try disabling WMM and try.

Sounds like max rate is set to 54

Any wireless mode at 20Mhz (upto 145Mbps) runs in single channel so you will see half duplex speed.

I would check your wireless mode settings in the router and also the wifi devices is connected. Wireless mode can be at 300Mbps (40Mhz/Dual channel) yet wifi devices still may connected at lower Mbps less than 145Mbps which falls to single channel and causes the speed results you seeing

Re: Speed drops by 50% with WNDR3800 wireless

Thank you very much for the quick replies. I have found the problem thanks to your suggestions.

When trying to check on the speed configuration as suggested, I discovered my HP Envy m6-1125dx notebook has a Ralink RT5390R wireless adaptor that apparently does not support dual band! Who knew that HP saves a couple of bucks in this way? The Ralink adapter is indeed maxed at 54 and can go no faster. Very disappointing. I have done some research that indicates the notebook will support an Intel Centrino Advanced-N 6230 P/N 670691-001. To add more complication, this is apparently not the correct P/N and some sources claim it is actually supposed to be P/N 636672-001 described as Intel Centrino Advanced-N 6230 half-MiniCard - 802.11B/G/N (Most of World).

Don't know if I have the nerve to order and try this. Any thoughts?

If the ISP supplied the router you have no choice but to work with them since it's "branded". Not providing the router's password is strange though. It may their way of preventing users from fooling around with the settings.

Re: Speed drops by 50% with WNDR3800 wireless

That's exactly what it is. The installation tech said they don't want any changes made or customers calling to find out how to get into the router if they have forgotten their password. I'm not real comfortable with the tech and all the customer service people, etc. having access to my router though. You never know when an employee turns into a disgruntled employee...

I would consult HP support for compatiity

If laptop uses half mini pci then should work.

Most ISP will give customer with user/pass but if your ISP wont then I guess you live with it or time to move on

Re: Speed drops by 50% with WNDR3800 wireless

That's exactly what I will do. I assume if the card is available, it will cost as much as a new notebook. Maybe I will have my internet provisioned for the available 18Mbps service since that seems to be the max speed my wireless can handle. It doesn't make sense to pay for something I can't use.

Don't forget you're talking about two different things wired which does work and wireless which is slower. The whole reason for fast ISP is so multiple users can surf or download simultaneously without slowing down.

Re: Speed drops by 50% with WNDR3800 wireless

If you change to 18Mbps I bet wifi will be half of that

I would use USB wifi adapter if you can not find good price in half mini pci

Try look on eBay

Re: Speed drops by 50% with WNDR3800 wireless

Thanks for the advice. I think we will stick with the 30Mbps because the price difference on the promotion was not great and it may drop further on wifi if we downgrade further. That is also a good point about the USB adapter...I didn't think of that.

We like the new provider (SureWest) but their decision to lock down the router seems to cause more problems than it prevents. When I tried to setup our wireless printers, I found that the 18-character Network Key hard-coded into the router is too long for the printers (new ones) to accept! I contacted SureWest but their tech support said they can't change the Network Key, and all they could suggest was for me to come to their office and "rummage around" to see if they have a router with a shorter Key. Oh boy.

Thanks again. This forum really helped me.

Re: Speed drops by 50% with WNDR3800 wireless

Thanks for the info on the USB adapters. Will that little N150 actually be able to take advantage of my full 30Mbps internet connection over wireless?

Why not... N150 is 150Mbps max and your internet is 30Mbps. Smiley Happy

Re: Speed drops by 50% with WNDR3800 wireless

That's interesting. I have the exact same speed issues with my SureWest WND3800 w/ 30 Mb service. When I had 18 Mb service I had the full 18 up and down and after upgrading to 30 Mb I get under 18 Mb down and around 22 Mb up. The difference is that I am getting the slow speeds with a completely WIRED connection! I am quite disappointed.

I called SureWest and they told me that you can expect a 50% bandwidth drop with the use of any router, even if it's a wired connection. Sounds like mallarky to me. I have yet to test the speed with the router bypassed, but I plan on trying that tonight.

Your Surewest ISP had no idea what they are talking about.
