Aspire V3-772G-9460 Product Information

I'm looking hard at buying the Aspire V3-772G-9460, but I'm trying to clear up some conflicting information before I do so.

 

First, the product page lists the Wifi compatibility as 802.11ac, but 2 of 2 reviews on Newegg state that the laptop is, in fact, 802.11agn. Is anyone able to say for certain which is the case?

 

Second, the product page shows the laptop as completely black (same as the other 772G models), but nearly every other site that sells this model shows it with a silver keyboard. Again, is anyone able to clear this up for me?

 

Thank you for your time.

    Welcome aboard, Bob. The first two sets of numbers (V3-772G) are the model number. There are variations within the model, though, and the last set of numbers (9460) describes a specific variation.

    Thank you for the response, but unfortunately this does not help much. I'm sure I'm comparing the correct variants. For reference, here is the Acer product page: http://us.acer.com/ac/en/US/content/model-datasheet/NX.M8SAA.004. And here's the Newegg page: http://www.newegg.com/Product/Product.aspx?Item=N82E16834314160.

     

    EDIT: Also the store page lists 802.11a/b/g/n, instead of 802.11ac like the product page.

    Bob, you're right. In all the reviews I've checked, I've never seen this before.

    Okay, time to improve our knowledge: Bob is right, but I had no idea what he is talking about, so I researched it. This is an over-simplified explanation of what Bob said:

     

    802.11 refers to two things: the number of receivers that can be on a Wi-fi network, and the technological level of the hardware involved. Because technological advances are not always consistent, some earlier versions are incorporated into later versions, and some versions are no longer in use. Unlike some other wireless set-ups, the different bands on 802.11 do not overlap.

     

    The "a" version is not the first 802.11, but it is the most widely accepted. The "c" refers to various additions and improvements. The 802.11ac is predicted to dominate world Wi-fi systems by the end of 2014. Acer states that this is the Wi-fi type for the laptop Bob is discussing.

     

    Some indignant reviewers have stated, however, that the laptop has 802.11agn. The "g" and "n" are newer, better systems than "c". They have better speed and security than "c" and the "agn" system MIGHT include all the improvements that were made with "c".

     

    In other words, Acer improved the quality of the Wi-fi system on this laptop without stating this in the advertisement.

     

    Now, if any brilliant person can correct me or improve this post using simple terms, please feel welcome to do so.

    This is mostly correct, except for a crucial detail. 802.11ac is wholly distinct from both 802.11a and 802.11c (aside from being based on the same technology, obviously). An 802.11a/g/n compatible radio is compatible with 802.11a, 802.11g, and 802.11n. Of these, the latter is the closest to 802.11ac. Still, the peak throughput of 802.11n is 150 Mbit/stream while the peak throughput of 802.11ac is 866.7 Mbit/stream. This that and a few other technical improvements, 802.11ac has roughly 10x the total throughput of 802.11n. It is also guaranteed to be dual band, whereas previous standards are not.

     

    802.11ac is decidedly superior to 802.11a/g/n, and if not included would lower my perceived value of this laptop. Further, if it is incorrectly marketed and does not actually include 802.11ac, I would likely return the laptop on principle. Thus, I'm trying to do my research up front and avoid that hassle.

    Thank you, Bob. Am I correct in understanding that any version of 802.11 will run on any other version, but perhaps not as well? Or is it that any version of 802.11a will run on any other version of 802.11a? I would be surprised to learn that 802.11 ac would not run on 802.11agn.

    Each new standard is fully backwards compatible. 802.11ac, being the newest will work on 802.11a/g/n networks/equipment. Of course, you would lose all the benefits of ac, as you're only as fast as the weakest link.

    I would never buy an Acer Aspire.  My 3 times booted up Aspire I V refuses to boot up while the fan just cycles on and off. There are other posts online about this problem.  Acer has not addressed the problem nor do their "chat" people know anything about it.  Only answer is to mail the computer to Acer to be repaired.  Computer is needed by an online school student.  Acer needs to do a better job of quality control before I would recommend one of their computers.

    Thank you, Bob. Part of the problem is that sites with information on WiFi are not dated. I can find a variety of sites differing on what is the latest or most common type.

     

    I do understand that ac absorbs all the benefits of n, but I cannot find out if that applies to g.
