Dlink cardbus wireless cards

[r3n4ud]

Was wondering what the differences are between the Dlink DWL-G630 and Dlink DWL-G650? I thought the main difference was that the G630 was capable of up to 54Mbps and the G650 was capable of up to 108Mbps, but when I checked out the boxes of the cards, both say they're capable of up to 54Mbps.

I check out Dlink's website and they also claim the G650 is capable of up to 108Mbps, but the box says otherwise. Anyone have any experience with these cards to solve my confusion? Seems like I'm missing something...

The 630 is standard 802.11g and will do up to 54Mbps. The 650 is Super-G and will do up to 108Mbps (with compatible hardware i.e. a Super-G Router / Access Point). If the price difference is negligible or you're wanting to build a Super-G network I'd go with the 650, otherwise the 630 should be fine.

802.11g is standard. super G is not.

Thanks for the info, that cleared things up.

One other thing. Is the only way to connect at 108 Kbps, or up to, (with DWL-G650 card) is to change the settings in the Super G Dlink router to allow for higher speeds? Or should the router know the card is Super G and connect more than 54Mbps? Not sure if I made myself clear. If not, I'll try to exaplin better.

If the card and the router / access point use the same Super-G standard, there shouldn't be any need for special settings. If you have two different types of Super-G, they'll usually fall back to regular 802.11g 54Mbps. If you're comfortable with it, you can probably find a Mini-PCI wireless card that will do what you need. The main thing for Super-G compatibility is that the chipsets are the same. For example I have a Netgear Super-G router at home which uses an Atheros Super-G chipset and I just recently installed a Gigabyte Mini-PCI Super-A/G card in my laptop which also uses the Atheros Super-G chipset, so I can connect and transfer at 108Mbps with no problem and no extra settings.

Sounds great. Thanks again for the help.

Don't mean to hijack this thread, but I have a related Q or two.

I'm in a rural area with no access to hispeed except for lugging a laptop into town. Its an older Compaq 1700 running ME with an Air Plus G DWL-G630 rev C card.

I also have a DWL-G122 USB wireless adapter; I'd thought I could set up an ad hoc network at home with it on my other (XP) computers. But I somehow made a real hash of it by opening both the Dlink software and the XP wireless wizard...

The laptop with the 630 works fine at the coffeeshop hotspot, but that computer has Trend IS on it, which gets real upset about any changes in its 'oversight' of network stuff, and they use non-standard terminology- I'm never sure about what they are saying about changes to the profiles.

SO... I gave up on that for then, and found that a flash drive did most of what I wanted pretty easily. But now, I'm getting interested in a wireless IP camera, which I understand can also connect ad hoc- so I could finally do stupid stuff like 'SquirrelCam'.

My Qs: how do I best straighten out the fouled up connections, and which is better- the XP controller or the Dlink software? (The ME must use the Dlink software tho)

If I go ahead with the camera thing, can an ad hoc network daisy chain from a camera to a laptop to a desktop? This is really a distance Q, the hard drive on the laptop is kinda small.

The D-link DWL-G650 Rev.A, J & P has Intersil Prism chipset. The Rev.B and C, uses Atheros chipset. Rev.K was TI, Rev.L was ADMTek, Rev.M was Realtek.

Atheros Super G was not very firendly with 802.11g only networks when 108 speed was enabled. I do not know in what chipset version this was fixed.

The original D-Link DWL-G630 I think it was Marvell based. Rev.B uses TI chipset acx111 (the same as Linksys WPC54G v2).
The DWL-G630 Rev. C & D uses different Atheros 54Mbs chipsets. Rev.E revision is Ralink based.

Basically even if you buy the same card model from the same vendor, if you get a different revision of the card you may end with a totally different set of features (like supported security), drivers, and compatible OS.

[ahhaa]

ofb- you sure know your stuff! :] I wondered why these were on sale at rockbottom prices...
... so, does that suggest using the Dlink software or XP's as the more adaptable approach?

say, what do you do down there in Costa Rica? Is it as nice as they say? (Wasn't Jurassic Park made there?)

thanks for the info!

Hi ahhaa. I know a bit about these cards because a while ago I was investigating witch one was best supported in Linux

I think that these cards were cheap because manufacturers want to sell more of their newer/fasters models than the old but proven G cards. But that's my though.

For most people the D-link software should be OK. For me I dropped using card software and started to use XP (after installing this patch: http://support.microsoft.com/?id=893357) because I enabled WPA2 security in my home network.

Changing subjects, I'm a DBA and system administrator of an application that runs on an HP Appha server (Still using Open VMS 7.3-02).

Here is very nice. It is quiet, nice beaches, nice mountain and volcanoes (Arenal, Poas, Irazu, Turrialva, Barba, Rincon de la vieja, etc.), Rain forest, no army, and in top of all that really good



Regarding Jurassic Park, some scenes were filmed in Costa Rica in an island called Isla del coco.

In the first movie they took a scene that is supposed to be in San José that was all wrong. San Jose is located in the mountains. And according to the movie it was in the coast.

[ahhaa]

Sounds great! Hilarious on the Coco page how the email addy flips...

yeah, the movies... recently saw again one of those jawdroppers that nobody but me ever seems to notice. In Nevada Smith (Steve McQueen), Steve is riding in a buckboard across this vast flat desert; at what, mebbe 10mph? The buckboard gets right up to the 'front yard' before he notices his parents cabin has been gutted.

this might be of interest to you?

Hi ahhaa I like the idea of the locating friends by the phone, unfortunately in this part of the world there are not many useful maps.
