r7800 vs r7900
Setup: r7800 firmware 1.02 r7900p 1.03
1400 sq ft two floors
All speeds in mbs repeated 5 times
R7800 5ft 190 r7900p 643
20 ft 200 r7900p 225
Upstairs R7800 110 r7900p 95
Downstairs r7800 150 r7900p 215
From the snb and this forum the results run contrary to the expectations. What are any lessons learnt with 7800 to try to correct this?

- Ok. Tried a used r7800 which I obtained separately. That worked at 630 mbps at 5 feet. And 415 at 20ft. Mu Mimo was enabled and ht 160 did not make a difference.
Signs of a crippled r7800. Wan port kept dropping out. Also the setup would not allow for an AP mode easily. Compared to r7900p though so far it’s been similar. The price of a used one would make this a choice for the 7800

the last 15 versions of the R7800 firmware have been 1.0.2.xx so just saying your on 1.02 doesn't help a whole lot.
Your testing doesn't tell us much either. Many different factors influence wireless speeds which is why its good to use as an indicator of a problem but to nail down exactly why you aren't maxing out your speeds, is a challenge.
the R7900 is triband, which wireless channels are you connecting on?
Is there much wireless interference in your area (a wireless scan)?
Also device makes a big difference. I've had the same device test remarkably different on the same router.
What are you testing with? Have you tried your testing with several different devices to compare the speeds as well?
the R7800 also supports 160hz wide channels which is how it enables its faster speeds. Does the device you're testing with support this? Not many devices do (its getting better) or if they do, aren't using it.
Is QoS turned on? This impacts speeds
I could keep going on with things that impact wireless speeds from time of day testing to housing materials. For instance, whenever I install a new router in my place, I probably move it 3-4x just to optimize its placement for better speeds. So its tough to tell you why specifically your R7800 isn't faster than the R7900 that you're testing against without a ton more details or playing around on your part. And even with that, we still potentially couldn't tell you.
- Good points. 7800 1.0.2.62 7900p 1.0.3.8 All on the same day. Testing for those numbers were with an iPhone XS all on the 5 ghz channel. The 7900p was on the first 5ghz channel. Then using a t480 Lenovo laptop the numbers matched at two spots 6ft and at 20ft. Did not check up and downstairs. Qqs not enabled on both. Not sure how to test differently to your question about the polling method, but the same spots were used with the iPhone to measure the transmission rate. I cannot get insight to work to attach the devices to measure signal strength so use transmission as alternate.
If the channels interference is so severe then I guess the triband 7900p helps?You can download free programs online for either pc/mac or from an app store for channel scanning.
Triband does have its benefits. I've got around 20+ 5ghz devices so its nice to seperate them out a little bit.
Again, wireless speed testing is nice for an indicator of a problem (is there?) or are you just testing to see which device works best for you?
I test a lot of routers and can get different results each time I test, with different firmwares, different time of days, different wifi channels, etc.
I'd recommend playing around with both routers testing different locations, different wifi channels, or even just getting all your devices connected and seeing which device performs the best. I've got a RAX200 that I've had the best single speed from a router but I still go back to my orbi because its consistantly faster over the whole house and provides better coverage. it might be peak speed slower but its much better at distance.
