Intel Wireless-AC 9260 + Netgear R7800 (X4S)

Recommended Posts

mobilenvidia

Got an Intel Wireless-AC 9260 card last month, these support 160Mhz channel width

Just now grabbed a Netgear R7800 (X4S) 11ac router
Only got them to have a play both were cheap and WIFI is something I like to tinker with

I chose the X4S as it support 160Mhz channel width (well 80+80Mhz)
I should be able to connect at 1733Mbps, will be interesting to see performance at this connection speed

I can get just over 50MB/s at 866Mhz connection speed, to a Netgear R7000 router at 80Mhz channel width
Am hoping to approach 100MB/s

Will have to keep an eye for bottle necks, spindle drive will probably freak
Server with RAID6 array is good for 300GB/s read write
May even come close to maxing out the Gigabit switch
USB3 SSD drive directly in Router should give this a go

There are better, faster, much more expensive Routers, but not much use when can only connect at 1733Mbps

Anyway it will keep me off the streets as the nights get longer and colder
Anything wanted to be tested let me know

I've been using the same R7800 for a while and I love it! I'll be interested to read your experience with it.

You running stock FW or DD_WRT or something else ?
Might give Vox's a go

Been running Tomato by Shibby for a few years on the R7000, but Tomato doesn't support Qualcom CPU's
R7000 has been rock solid since I had it, no need to really replace it, but wanted to test 160Mhz

I'll be back with some results once the router turns up

We seem to be on the same path - my previous was a R7000. Just stock FW here though.

Let the pictures do all the talking

Download as fast as 1GB LAN connection can pump out
Upload a bit slower but still faster than 866Mbps download connection on 8265 I hadI

'll make some comments on the Router when I have a chance

That''s impressive! About twice what I'm getting!

Performance can't be faulted, very impressed with this

Router however, has some issues
Biggest for me, in AP mode USB doesn't seem to work
I save the Server backup to a USB stick in the R7000 running Tomato, easy peasy

The R7000 running Netgear FW in AP mode I can't enable FTP from internet, internal FTP works fine but no use from server getting to USB

The R7800 in AP mode I can set FTP from internet BUT USB is not working or the USB3 stick is not recognised, annoying

Took a few goes to get 1733Mbps connection up, first no wifi was broadcast at all

Quite slow in rebooting, especially Wifi takes ages to come up, 1.7Ghz dual Core CPU but 1Ghz dual core R700o is much faster in boot up

Antenna's a bit naff bit hard to keep tight

I'll try either DD-WRT or Vox FW to see how USB gets on

DD-WRT only thing that seems to work is straight 160Mhz + using 3x upper channels, I can then get a 1.7Gbps connection
But download is about 500Mbps upload 330Mbps, way down on Netgear Firmware

Got FTP working again, forum backup are safe again
Went to Kong build

Can only get 160Mhz to work on channel 128 using 3x upper channels
80+80Mhz seems flawed as it only seems to add 2 more channels
Had kinda expected this to work other way round

Impressive speed at range

Bedroom about 20m away, through 3x walls or down hallway, 50MB/s throughput to Satellite PVR, this is probably maxing out its connection to the switch
Connected up a 780Mbps to probably won't get much more then 50MB/s

Today's job to go back to std FW to get the speed
Setup Router to mode and do only AP funcitons, to see if FTP from WAN will work

It sounds like you're making progress! I'll be interested what you get with standard FW. (You're about the same distance and #walls as I have.)

I seem to have the router sorted in Stock FW and in 'Router' mode turning off DHCP forcing it to a static IP
This 2 goes, first time it lost the static IP I gave it,  r7800 worked, but could not access it to change anything

FTP allows me to set internet access, still need to confirm this

I'll turn the server back on so no bottle necks other than 1Gb network
Time to do some distance testing

Below wifi at 3m, in lounge infront of TV where we normally sit at night

And 20m away in bed room, don't really use it here but as far as I can get from router
3x walls or 1x hallway to get signal here

Tried channel 128 and 161 as the base but channel 36 gives best results
The router info page says is uses channels 36.40, 44, 48, 52, 56, 60 and 64, pretty well the entire the lower channel range gobbled up to have 160Mhz
Not very neighbour friendly if you are in the city taking up 8 channels

Very impressed with performance and range
The router SW is a bit blah.
USB3 port quite slow got to about 10MB/s, fast enough for backup download but only just
Wifi takes ages to come on after a reboot, but now set I shouldn't need to tinker again

But overall very good, now what to do with the R7000, done me very well over the years

FTP works internally and externally but only if coming from internally
grrrrr, something in r7800 is stopping it

:laola: 

Finally sorted this stubborn router on Stock Firmware

1.7Gbps sorted, full connection and speed (DD_WRT fell down with full speed connection but 866mbps performance)
Running 11ac on channel 36-64, DD-WRT only worked on channel 128
AP mode set, setting dedicated IP on router doesn't work router not reachable everything works but no GUI as router IP in cyberspace, setting IP via my main router does work
FTP from interweb now works, forum backups are safe again

USB sometimes won't connect, not sure what is afoot here, need to remove and reinsert again for it to show
I'll keep an eye on this as no more need to tweak.

I'll try USB on mine when I get a chance, just to see if it behaves the same.

Hmmmm, USB seems to go to standby mode after a time
As this morning USB not visible, no LED

Wonder how one wakes it up

From what I can find, the 7800 doesn't have a USB power saving mode. If it's a "green" drive, it might be powering down on its own.

USB stick seem to be issue but only in the r7800
Works fine on laptop
Tried another USB stick and its working fine on r7800

Formatted USB3 drive to NTFS and still no go

This is so weird

Ordered a new 128GB USB Sandisk Ultra fit will be better for ever increasing backups now approaching 7GB ea
Previous 64GB bought back in days of USB3 infancy and much clostlyness, still works in everything but r7800

Just trying USB stick in Satellite/PVR and all is well in there
Also runs Linux, much easier to setup as Telnet/SSH has useful commands unlike r7800

Tempted to forego r7800 for server backups, and use satellite receiver, with the tiny USB stick coming, I might be able to close the front door and not see it
Maybe even use the 4TB drive in there, which is also filling fast, but this spins down, may cause issues as takes a few seconds to spin up.

It sounds like that might be the way to go. I tried a 32GB stick in my r7800 and it's still showing, but it's a couple of years old. Maybe newer sticks have power saving features the r7800 doesn't know how to deal with.

I don't think its power saving feature any more
If I plug in 2x USB sticks, the 64GB (as above) comes on and within minutes dissapears, the other a 16GB happily stays on

Not sure whats going on there.
I'll stick with Satellite PVR to do the backups, the old 64GB stick still there this morning even with PVR asleep
I think Netgear are possibly could do better with some aspects of their gear
Performance and Range top notch, other aspects leave alot to be desired, ie the GUI is pretty rubbish in over scheme of things

But I bought to play with the WIFI and 100MBps performance is great.

It's interesting that smaller sticks work. I wonder if there's a size limitation (or bug).
