What kind of modem do I need?

Been thinking of switching from ATT to Comcast for over a month now.

I would like to have wireless internet(since I have a laptop),so..

Should I purchase a wireless cable modem

or..can I get use any Comcast approved modem..and than for wifi,I would need a router..yes?

I should mention that my laptop is the only computer in the house..which is I do not currently have a router

I'm kind of confused about this..so I want to make sure before I purchase any hardware.

By popular choice, most prefer a separate modem & router. You can purchase your own modem & wireless router.

 

For modems, please review Comcast's approved modem list: http://mydeviceinfo.comcast.net/

Re: What kind of modem do I need?

I am leaning towards a Linksys WCG200 or Netgear CG814

Any advantages one has over the other..or disadvantages?

Yes of course if you desire that capability. A wireless router will still have some wired/ethernet ports available (typically 3-4) if you desire some wired connections as well.

 

You mentioned a Linksys WCG200. First, my advice is to avoid those all in one gateway devices and always go with a stand alone router and separate a modem. Second, that device is an older model and it has been classified as being "end of life" as of 3/09 on their Approved Modems List.

I agree with EG about gateway devices. Too many inherent issues. As for wireless routers, there are quite a few newer wireless routers. Recommendations for wireless router will be opinion based.

 

Brands like Linksys/Cisco, D-Link & Netgear will have what you want.

Re: What kind of modem do I need?

For a router,I am probably going with either;

Netgear WNR1000  or

Linksys WRT310N

 

for a modem,I am thinking of going with one of these;

D-Link DCM202

Motorola SB5120

Motorola SB5100

Terayon TJ716x

 

 

I'd appreciate any thoughts...

I'm assuming you are trying to keep a budget on gear purchases from your choices you presented.

 

Either router will be adequate; however, the WRT310N is known to have issues.

 

Modems: stay away from the DCM202 & TJ716x.

As for the Motorolas; if you can find one to purchase not on an auction site, they would work. An SB5101 would be the best choice. FYI: modems via places like Ebay can be stolen or hacked.

 

If I'm wrong about a budget, consider a newer DOCSIS 3.0 capable modem. The other modems you mentioned will limit your HSI Tier choices

 

Consider modems such as the Motorola SB6120 or Zoom 5341j

Check Amazon for some good deals.

Totally agree with Johkal on his advice and also agree on the term "adequate". Those are basically bottom of the barrel budget minded choices for routers.

Re: What kind of modem do I need?

HSI.....High Speed Internet

Speed tiers vary in speed ( and price......!)....from bottom-rung ~3Mbps to Extreme 105 (assuming Comcast is your ISP......)......

Have had very good luck running Extreme 50/10 here - modem is a Motorola SB6120....
Good luck!

Re: What kind of modem do I need?

The router is basic, but would work. Keep in mind that it is a "G" router. If you have any newer PC or laptop that is "N" capable, it will bump down to use "G" and will not get its full potential transfer rate.

 

To understand G & N protocols, here is the Wiki: http://en.wikipedia.org/wiki/IEEE_802.11

 

It's a lot to take in, but happy reading! :smileycool:

I noticed that the WNR1000 does require a wireless N adapter..unless my laptop has integrated wireless N..not sure..It is is a Compaq Presario C500

Re: What kind of modem do I need?

"N" routers are also "G" & "B" capable. "N" routers will bump down to "G" if that's what your laptop is using.

Not sure what that means?

Re: What kind of modem do I need?

So, the best you can do is Wireless G. Your Router should support that as well as Wireless N. If you want the faster speed of the wireless N you should be able to swap out the Wireless adapter to get the wireless N speed.

The easiest way to find out if an "N" wireless adapter is available for your laptop, is to search upgrades on the manufacturer's website. Once you have identified you can replace it & you know which one you need, you can shop around on Ebay or vendor sites. Swapping it is usually simple. Access to the card is normally under the laptop behind a removable panel.

If you have a laptop, go into device manager and disable the Broadcom WLAN adapter.

Procure a Wireless N USB adapter that you can plug in to one of the USB Ports.

If you have a desktop with an Integrated Wireless Adapter then the process is similar to that of the Laptop with the exception that you would then have a choice of a USB adapter or a PCI plugin adapter.

It's normally cheaper to buy a card for the laptop rather than an external adapter. It's his choice, but I would rather replace it.

You don't have to upgrade at all. "G" devices will work perfectly fine with the new router.

Yes,I realize that G devices will work with it..but to achieve N speeds,than it will require the adapter(or some other method),right?

 

And I would indeed feel better using the adapter,rather than swapping.Something about taking a screwdriver to my laptop and tinkering with its guts,makes me just a little uneasy:smileyshocked:

 

What I will probably do is go with a Motorola SB6121 modem and a WNR1000 router,and than once I see what speeds I get,decide whether or not I want to upgrade to N.

 

Thanks for all the advice guys.I appreciate it.
