R7800 SmallNetBuilder Review

[janthony6]

I’d like to see an updated review for this and the r9000 using Voxels firmware. I’ve updated and constantly changed routers. Pairing the 7800 and 9000 in my house has provided the most stable, furthest reaching, and fastest experience.

 

[tyreman]

does this router do https out of box or is there a setting

No it doesn't, its been a requested to Netgear as a new feature but nothing came of it. I wouldn't hold your breath.

do I need cfw for R7800 to use custom port for dns or dnscrypt ?
(most isp on my country use transparent dns proxy on port 53)

Hi all
Just purchased this little beast
Surprised for now how good it.works.
Some questions based on the review I ve read are the following:

With the box 'Enable 160mhz' ticked and an intel ac9260 wifi card(which is 160mhz capable) I should see 1733mbps connection speed in windows properties?
Also does this mean that full bandwidth of the 5ghz band will be occupied with this connection and all other stations connected will wait for their "turn" so as the router to serve them?
And lastly I think, if this laptop will use 5ghz whole 1760mhz bandwidth, this means that 2.4ghz band will work just fine independently of the load on the 5ghz band?

Thanks for your time and reading

Yeah bands are independent. The router can connect to a 4x4 (4 antenna client) at a max link rate of 1733 Mbps at 80Mhz channel width on 5Ghz (Link rate doesn’t equate actual speed which is dependent on distance, interference and overhead). It can also connect to a 2x2 (2 antenna client) at a 1733 Mbps max link rate at 160Mhz width. Also note that at 160Mhz width range is reduced relative to 80Mhz. At best expect no more than ~65-75% of max link rate at close range, when it comes to actual speeds. Lastly you will also be limited by the fact Gigabit Ethernet means no more than 900-950 Mbps.

So despite ac9260 is 2x2 with max speed at 1,73 and netgear is 4x4 1,73, netgear will be able to deliver 1,73 at 2x2 at 160 mhz ?? Ok, in an ideal world So adapter properties will show over 866,7 that my ac7260 shows now, ok ideally 1,73gbps, if it is set at 160mhz?? Netgear will switch itself at the correct 160 mhz width?

In another adjustment when not 160mhz width is used or set, it will be able to serve two 2x2 (thanking mu-mimo) at 866,7 gbps at the very same moment? For example my ac9260 laptop and my 2x2 maximus viii formula wifi adapter or samsung s8 which is 2x2 mimo.
Right?

 

[avtella]

Yeah it automatically sets to 160Mhz when it can, but I believe it prioritizes MU-MIMO over 160Mhz so it will more likely use 80Mhz width with two or more MU capable devices active. It’s more likely to use 160Mhz if using the lower numbered channels (36-48) for some reason. Only time I have seen it use 160Mhz is when I used my laptop on a second R7800 with no other 5Ghz clients. The Galaxy S8 uses a Broadcom WiFi chip which is known to drop to 433 Link rate with MU-MIMO active. MU capable Broadcom devices have issues with MU-MIMO. Most new high end laptops use Intel 8265 or Killer 1535 (Qualcomm QCA1674A) both of which support MU-MIMO well and also most android phones using the Qualcomm WiFi chips like the Nexus 5X etc. If you have a S8 you can still enable MU as I don’t think that lowered bandwidth will be much of an issue on a mobile device.

Overall don’t expect miracles with MU-MIMO though.

Just gotten a r7800 to pair with 9260ac card. enable vht160, Link rate shows 1,73mb/s. Tested by file copy a 1GB file n got 105MB/s dwn & 80+MB/s up. Laptop n router 2m apart direct in sight.

So is this 105 mb/s close to 1,73 mbps at least? Also the copy was between one wireless station that had "overtaken" the whole wireless bandwidth and a wired station?
Maybe something is wrong with my maths?!?

1733 Mbps is a Link rate (theoretical), you will never reach the link rates you see, expect around 60-80% at best but with the a 1733Mbps link rate on the R7800 I hit a max of 112-114 MB/s (Intel 9260ac client) sustained which is 912 Mbps which is pretty close to Ethernet limit which is the real bottle neck. Unless you have faster than Gigabit LAN or WAN connections you won’t get above ~950 Mbps even if the WiFi rates are faster.

Can you please share the wireless settings of the r7800 ? I've just got an ac9260 in my hands but it is limited to 866 as my ac7260...

No other connected device at 5ghz, only my ac9260 laptop and one at 2,4


EDIT:: Just enabled HT160 at the R7800 and voila 1,7gbps Thanks!!

EDIT2:: Very limited range...jumps at 1,1 or 867 over 7,5ft (3m) away

 

[avtella]

You need to use lower channels for HT160, I guess the 9260ac needs a continuous 160Mhz, I don’t think it can do 80+80 split bonding. In addition range at HT160 will be much lower. Nice for test purposes but stability is better on HT80. It would frequently drop below 1.3 Gbps to 500 or so Link rate and HT80 would stay at a solid 866 Link almost everywhere in my home.

So if I want to do so, I'll just disable HT160 and the 9260 will work just like the 7260, right? (At least for a start it seems that in my further room link stays at 760 mbps or at 867, so I guess I'm ok for now)

Just for testing, even at the same position link rate goes from 1,7 to 1.0 or even 866...is this a case of energy saving of the card or what you call stability?

Can u check if u can get the 9260 connected at DFS range of frequencies?
I tried few times setting the freq in one of those DFS channels it will bond into 160mhz b/w for <1min then jump to channel 36 but still 160mhz b/w.

 

[moron+genius]

Anyone able to get this working in DFS channels?

 

[jsmiddleton4]

I've only been able to find full length cards and my laptop only has room for the 1/2 sized ones.

Thanks for the info. Would you, by any chance, be able to see which country have these frequencies enabled?

Modern linux, it's pretty easy - just type "iw list", and that should show the current regulatory domain and what channels are supported (plus other useful info) - ChromeBooks follow linux rules - so the Intel WiFi chipsets are fairly open for DFS channels.
