Posted on 11/17/2012 1:00:04 PM PST by raybbr
I have been using a Motorola 3360 ADSL modem for over a year. Well, not the same one. Last Thursday, the third one in the last year crapped out on me. (I needed one right away because my wife is job hunting and we can't wait for delivery. )
I decided not to go with another Motorola. I went to Staples and found that they have two available in the store. One is a Netgear 600N single channel and the other, which I purchased, is a Netgear Model: DGND3700-100NAS, which is a dual channel modem. It has both the 2.4GHz and 5.0GHz channels.
I asked the guy at the store how I would be able to use both channels on my laptops and WII. I got that "Gee, I wish he hadn't asked me that" look.
I had $50 dollars in credit and, reading the box, decided more would be better. As in more bandwidth.
I got home and was set up in less than hour.
Now comes the good part. None of my laptops have a 5.0GHz adapter and I found out the WII doesn't either.
The IT guy at work lent me his USB adapter. It only picks up 2.4GHz.
Here are the questions:
Can the router be configured to run both channels at 2.4GHz?
My laptop with the USB adapter is showing that I am picking up my network twice. Does that mean I am connected through both the USB adapter and the internal adapter at the same time getting massive flow to my router?
I have checked my Device Manager on all the laptops and have found that none of them have a 5.0GHz option under the internal adapter.
Do you think it's worth it to get another adapter capable of 5.0GHz?
I know I could call Netgear but all the reviews regarding them means a call to India or Malaysia with hours of aggravation. Tech FReepers are far more intelligent anyway.
Thanks for help in advance.
Pinging the tech gurus that I know...
Grab whichever frequency has the least interference....speeds should be about the same...in fact, the wireless modem should broadcast in both freqs simultaneously...
It does. It's just that my laptops don't have the 5.0GHz adapter.
How does one measure interference?
My AP is a dual radio and I run both 5GHz and 2.4Ghz. Almost everything I have has 5GHZ, but I can’t really see a difference (except the microwave doesn’t screw up the airport for the kitchen stereo)...
But keep in mind, they are two discrete networks and must be setup individually.
I assume you are talking about an 802.11n (MIMO) router. It is my understanding that in practical application, due to the number of 2.5 channels in use, that the only way to get dual channels and the higher bandwidth is to go to either 2.5 + 5 or 5 + 5.
The wiki is very good: http://en.wikipedia.org/wiki/IEEE_802.11
Don’t worry about it.
Netgear Model: DGND3700-100NAS, which is a dual channel modem. It has both the 2.4GHz and 5.0GHz channels.
Lasted three months, junk.
What did you replace it with?
The wizard setup sucks...I always do manual setup. Not sure if you know how but it is the better alternative if you do. If not, that is your alternative.
Since your laptop doesn't have 5 ghz, you are not cabable of receiving on that frequency. Your laptop and router will automatically find a frequency that works, assuming you haven't disabled any of them. Good luck.
2.4 GHz is a longer wavelength and has a longer effective range than 5GHz.
5 GHz is mainly supported by some game boxes and phones.
If all your PCs are connecting at 2.4GHz, there is absolutely no need to get a new adapters so they can connect at 5GHz.
With a spectrum analyzer...not something you would do....just run your laptops on their existing 2.4GHz WiFi card....
Why do you want to use the other frequency? Usually it is because of interference issues.
For example, a leaky microwave in the kitchen will interfere with 2.4GHz.....
I have a desktop in my kitchen that whenever the Microwave is on can’t stream video...
I don't think so.
No, without extensive modifications you can only be connected through one network connection at a time. Find out which one has better throughput/stronger connection and shut the other one off.
Nah. But two router mods that I found to be helpful (if you can do them on the Netgear) were:
Basically the router has 2 radio transceivers operating on 2 very different frequencies that have different up and down sides. You can’t get a 2.4ghz to operate on a 5.2ghtz. What you can do is get an a/b/g/n dongle and plug it in to what ever device you want to run on the 5.2ghtz channel. My laptop 6y/o has a built in b/g, and i put a a/b/g in the card slot to get both channel. Upgrading the wifi in laptops or desktops is easy and under $50. (a dyi deal for sure)
Me too! a Belkin 600 DB has been serving here for almost 2 years.
my tail is still sore from the RCDD exam this morning.
You turned the internet off?
There was also a helpful suggestion of changing your WIFI card. Most laptops that is easy, but not all of them. Google for laptop's manual to see where it is located and what it will take to get it out. Definitely take in your existing card with you since they are not all the same. Sounded like you might be on a budget and not sure you are going to recieve that much performance gain for the dollars you would shell out.
If you’re looking for the N600 speed offered by the router you’ll have to get one of the N600 client adapters for your laptop. Plugging in multiple adapters, or using your built-in plus a USB external, won’t hack it.
There may be a third-party program out there that can bind your two adapters to act as one but I don’t know of any off hand.
I highly doubt it. Unless it's very unusual, it has two radios, one for 2.4 and one for 5, and neither can operate in the other band.
If your access is OK using the 2.4 ghz network, I wouldn't worry. However, if you are experiencing interference and can't fix it by switching channels in the 2.4 band, then I would go to the 5 ghz band.
I have two networks, one on 2.4 and one on 5. They are served by separate access points. I started out with only 2.4 and had problems with cordless phone interference. So, since my Mac already had 5 ghz capability, I bought an Apple Airport and switched over to that. Problem solved. I've since replaced the cordless phone with a $20 DECT phone that works fine and doesn't bother WiFi. Now I operate both networks, since I do have some devices that are only 2.4 capable, and all are working OK.
Oh man... I hate to just NOT answer, so I’ll be honest and just tell you that my “WiFi Kung-Fu” is weak. This week, I’ll try to ask around work and see if anybody has one of these NetGear WAPs and see if I can get a decent answer for ya. :-)
Yes, I kind of understood the basics. Thanks for the link it helped explain more.
Thanks for the link. Some helpful info there....
A router is in simple terms just a radio and needs certain receivers to receive different channels same as a tv to change channels your actually changing frequencies.
You have a 2 channel router that transmits at two different frequencies so you need receiver’s that receives two different frequencies...
I think he is confusing frequency and bandwidth. You don’t “get more flow” from using a 5 ghz device instead of a 2.4 ghz device... they are just different ranges.
Your bandwidth and upload / download is determined by your ISP and the equipment between you and the nearest switch.
True. I don’t think I have ever seen anything over 100 mbs out of a home router. Bandwidth is one of the most misunderstood words there is, if I got 1000 mbs cable but someone is only uploading at 56 k that’s what I get on my end LMAO!
