WVB WiFi bandwidth normal?

    Say people;

    Never had a mini client before, least of all a wireless one.

    But just had a C-41W installed in a detached garage and everything appears fine. Excellent signal strength, LED indicator on the client is solid green and the WVB's is solid blue.

    However I notice that on a WiFi analyzer app installed on my Smartphone, the WVB's SSID beacon shows only a 40 MHz WiFi channel bandwidth on the 5 GHz band being set. Yet when I survey around my neighborhood I notice all other DIRECTV WVBs are configured for an 80 MHz channel bandwidth.

    Could this be because my WVB is connected to only one wireless mini client and therefore the required throughput does not need an 80 MHz channel bandwidth so automatically sets the configuration to a lesser 40 MHz wide one?

    Thanks, just curious ...

    There are so many possible reasons it is hard to guess. Maybe the C41W can only do 40 MHz wide channels and the C61W is needed for 80. Maybe that's the widest channel it could grab based on interference (i.e. all those other people who have grabbed 80 MHz channels) or maybe it is based on signal quality and if it is strong enough it grabs a narrower channel to avoid wasting spectrum unnecessarily (802.11ax / wifi 6 will fix that issue) Maybe it is a firmware version thing.

    I'm sure others could think of more. If it works fine I wouldn't worry about it. Be glad it is being more spectrally efficient than your neighbors :)

    Ok well ...

    Had a tech have to return on another unrelated issue and for the heck of it asked him for the newer C-61W so he installed one.

    Same result, WVB is still configured for only a 40 MHz channel bandwidth. So whatever its reasons I won't bother with it as it's working fine this way. Though consideration for neighbors by unnecessarily using the wider 80 MHz WiFi channel bandwidth doesn't really seem to be an issue with the WVB as I notice they're apparently designed to operate only on the sparsely occupied DFS restricted WiFi chs. 52-64, 100-144 (i.e., the UNII 2 and UNII 2 ext. bands).

    Also (and again just for the heck of it) I asked the tech if he had the new WVB Gen 2 with Mocha 2.0 capability. But he not only didn't have one, but wasn't even aware one existed other than the built-in one on the HS-17. View attachment WVB2_manual_2017.PDF

    Using MoCA 2.0 on a WVB isn't going to matter until Directv ships 4K wireless clients. Even if you had an HS17 with 7 wireless HD clients you won't fill even half the bandwidth MoCA 1.1 is capable of, so there's no point for Directv to ship the new WVB yet.

    Even 5 HD and 2 4K wireless clients wouldn't max out 1.1.

    Yeah true ...

    But as I said this is my first mini client install and I wasn't too aware of the latest equipment available. So was just trying to get the latest hardware even if it won't provide any performance increase at the moment since I'm going to be stuck with it over at least the two year re-commitment that I accepted for the free upgrade.

    And yes, this is why I'm so tired of many of the techs during their visits insisting that networking my TiVos over the DIRECTV MoCa network is too much and will cause interference and slowdowns to the WH networking of the DIRECTV receivers.

    A number of them also annoyingly remove my Sonora triplexers I use the connect the TiVo receivers and a TiVo Mini client to the DIRECTV MoCA network complaining they are not "DIRECTV approved" devices. And I always have to put everything back together again when they leave.

    Sheesh ... haven't any of them ever heard of "Sonora Design Associates", which has long manufacturered DIRECTV and DISH compliant coax equipment?

    (granted, chiefly for MDU installs).

    Why would a residential installer need to be familiar with products intended for the MDU market? Probably easier to disconnect your Tivos before they arrive...

    Well to be honest for a long time I've fankly been somewhat confused as to the specific line of demarcation, or if even a well-defined one exist. Between an MDU installation and a residential one.

    As I many times see what appear to be standard DIRECTV (now ATT/DIRECTV) techs installing and making service calls to subscribers in apartment buildings for years now.

    How many customers per antenna? One residence is residential, multiple dwelling units is (by definition) MDU. If there is a shared antenna it should be an MDU.

    That should not prohibit a non-MDU tech from doing the basic receiver swap/cable extension within a unit (within certain parameters). But engineering the system would be left up to higher trained technicians.

    How are you telling the difference between a "standard" Directv tech and a MDU specialist while driving by???

    I'm sure there is some overlap and some handle both residential and commercial/MDU accounts - the ones who are better trained and would at least be familiar with the Sonora brand if not that particular piece of hardware you are using.

    My assumption was that MDU techs work for various firms providing, among other technical services, satellite installation and repair contracted by the MDU owners.

    And do not work for AT&T or drive their vans ...

    I don't know about MDUs, but if a commercial customer calls Directv they will get a Directv employee/contractor same as residential customers. Though the ones they send know more, either that or the one time I was out of town and my GM called Directv we got lucky that they sent someone who didn't run in terror when he found this was not a simple SWM LNB home type setup :)

    Oh wow ...

    Boy "I'm with stupid" ...

    No wonder my WVB's WiFi channel bandwidth is only at 40 MHz. I just checked the model number and it's a 1st gen model for MoCA 1.1, WVBR0-25 (mfr. by WNC) that can only do wireless-N (802.11n), so has a maximum ch. bandwidth of 40 MHz of course.

    Whereas the 2nd gen. WVB as in the document I posted, WVB2R0-34 (by Arris Corp.) can do wireless-AC (802.11ac). So can naturally have up 80 MHz, which is the model most subscribers must have.

    Last time I checked they never released the WVB2 to the public outside of some testers. I've looked online and don't see anyone selling any.

    Hmmm ...

    Any ideas then how a supposedly wireless-N bridge can emit an 80 MHz transmission?

    Just like I'm looking at my neighbor's WVB on a WiFi analyzer app right now and their transmission is reading as 80 MHz wide and mine is 40 MHz ...

    do you know for sure what device take the channel ? perhaps not WVB-2

    Well its SSID beacon says ...

    "DIRECTV_WVB_8571725F"

    And it's spectrum is right now spanning WiFi channels 100-112 for an 80 MHz width.

    (The primary 20 MHz ch. is 100).

    They have a HS17 which has an internal WVB2, there is no external WVB2.

    Yep ...

    And believe it or not while I was actually out running errands today my brain-lock suddenly opened and I realized that I must be simply picking up the SSID beacons of the internal 802.11ac WVBs of HS17s around the neighborhood. And was going to post this as soon as I got back.

    But you beat me to it ...
