Oh yes......of course I can tell.

Let start with your laptop, answer these few questions:

1) Did you update the laptop bios?

2) Win10 which version? 1803 or 1809?

Very well, download appropriate 'new' microcode update for your laptop

http://www.catalog.update.microsoft.com/se....aspx?q=4346084
2018-08 Update for Windows 10 Version 1803 for x64-based Systems (KB4346084)

and install it. Reboot.
Then run RWeverything and check if the PATCH ID changed from 84 to 96. (Technically, the latest microcode from intel is version 9A.)

If it is 96, then run TM speedtest, you should be able to reach 800Mbps via wired.

Oh crap....
https://support.microsoft.com/en-my/help/43...crocode-updates
Probably your laptop CPU isn't listed in microsoft database.

EDIT: it had came into my attention you mentioned the laptop is i7-8750H....., 4346084 should be able to install properly....unless your win10 version isn't 1803?

EDIT2: Huh, found the reason why 4346084 can't be installed in your case:
https://borncity.com/win/2018/09/24/windows...7467-kb4346084/
Quoting from the blog:






Wanna go old registry method to disable it?
KB4346084 is pretty much 'beta' by microsoft.

The other alternative is registry method.

Need to disable spectre protection. Reboot is required.

Normally, I would suggest deleting mcupdate_GenuineIntel.dll from system32, but since you mentioned you had updated the bios, this is not an option.

Impossible........when you run speedtest 800Mbps or LAN data transfer stuff, there will be one core/thread maxed utilization with haswell microcode 24 on win10.

edit: unless if spectre protection had been disabled in first place by you.

Disable WPS? Remember the WPS Reaver stuff?
How about changing the SSID? Remember the rainbow table for common ssid?
Use longer password? Remember GPU password brute force cracking is quite fast?
Disable TR-069? TM can't even secure its own network and you trust them to manage your router via TR 069?
Maybe change router admin login pass for obvious reason?

KB4100347 contains Spectre mitigation microcode.
KB4346084 contains spectre and Foreshadow mitigation microcode.

KB4100347 is the one pushed down to win10 users by microsoft.
KB4346084 is the latest, must be manually installed by user. But there is one quirk bug that prevent this installation as I quote from a blog post just now.

Nope, that windows10.0-kb4100347-v3 only contains Spectre mitigation microcode and missing Spectre Variant 3a (CVE-2018-3640: "Rogue System Register Read (RSRE)"), Spectre Variant 4 (CVE-2018-3639: "Speculative Store Bypass (SSB)"), L1TF (CVE-2018-3620, CVE-2018-3646: "L1 Terminal Fault").

You can check the microsoft microcode version and compare it with intel microcode version.

Ignore your desktop first.
Can you get full 800Mbps on TM speedtest via your patched laptop on wired now?




Something is fishy here.
Cause your cpu utlization.....as if Meltdown protection also disabled.

What is your powershell output? I don't really trust inspectre result.
https://support.microsoft.com/en-us/help/40...ings-powershell

Oh, that picture?
Let just say microsoft catalog and changelog kinda 'unreliable'.
Microsoft did updated KB4100347 to v3 due to overclocking+instability issue with broadwell-e.

According to https://portal.msrc.microsoft.com/en-us/sec...isory/adv180018 , "The required microcode is the same microcode that addresses CVE-2018-3639 and CVE-2018-3640"

The Summary of Intel microcode updates https://support.microsoft.com/en-my/help/40...crocode-updates
Microsoft should really fix the page formatting.
First table = Spectre Variant 2 (CVE 2017-5715 [“Branch Target Injection”])
Second table = Spectre Variant 3a (CVE-2018-3640: "Rogue System Register Read (RSRE)"), Spectre Variant 4 (CVE-2018-3639: "Speculative Store Bypass (SSB)"), and L1TF (CVE-2018-3620, CVE-2018-3646: "L1 Terminal Fault").

Hmmm , since microcode issue had been solved and you still get that same 500 Mbps to 600Mbps, you might wanna contact TM via livechat or 100 and request TM to 'refresh' your account. There were few users who got mis-capped at 450Mbps to 550Mbps (at PPPoE stage) and they got it solved after TM 'refresh' or 'reset' their unifi account status.
Hope the 'refresh' or 'reset' or whatever it is called by TM can solve your issue.

As for your haswell desktop, you can just rename mcupdate_GenuineIntel.dll at system32 and reboot. Be warned, the microcode is required for proper protection, it is not a good idea to disable it....

Agree, he mentioned he is using cat6 cable, but sometime shit happens.
In addition to that cat6e cable which he uses to connect his laptop to router, he also has to test the cable that connect BTU to router.

So far, the microcode patch issue only happen with windows 7 and 10. See for yourself on the impact of speed after latest microcode was applied.

I made some post on ivy bridge 3570k performance when the first spectre microcode was released.
https://forum.lowyat.net/topic/4547450

Then another posts on someone thread where the guy has haswell CPU.
https://forum.lowyat.net/index.php?showtopic=4649008
Had to inform the guy that latest microcode from intel somehow has less performance impact as I also have problem with the older haswell microcode for my i3-4330 and I5-4200U.

Linux and MacOS seem to have lesser performance penalty due to usage of retpoline.
However, after reading this https://bbs.archlinux.org/viewtopic.php?id=241738 , it seem as if the performance penalty also exists, although still less severe compared to windows .....someone might wanna reply at this archlinux forum......blacktubi, you wanna reply at that thread that the poster issue was caused by older microcode? Latest haswell ULT microcode is 24, version 23 is haswell ULT problematic patch.

Good, remember to update us after your account 'refresh'.
Make sure you use your laptop with updated microcode for testing via wired once your unifi account is 'refreshed'!



Moving on to your haswell CPU desktop.....
Disabling the microcode is not a good idea due to security concern.
Modding bios with latest microcode via UBU Tools is out of your league, maybe?

Perhaps a permanent pendrive stuck at your usb port?
https://www.techpowerup.com/forums/threads/...-loader.248858/

For one, Microsoft doesn't push microcode update for Win7, thus you shouldn't worry about it........unless if your hand is itchy and you wanna mod the bios, then you better make sure you select the correct microcode version.

Some mainboard vendors are very consumers friendly[I]......where vendors actually release bios with Spectre protection.......but they don't release bios with Spectre-NG protection (which somehow reduced the performance penalty).
So, if you are one of 'lucky' user, the only choice is to either fully disable spectre mitigation via registry or use the Intel Microcode Boot Loader.


I modded the bios and so I know the problem also occurred for win7.

But just to be sure, you better check the microcode version via RWEverything --->Access--->CPU MSR
Then compare both CPU ID and PATCH ID (this is the microcode version) with information from Intel pdf sa00115-microcode-update-guidance. If the patch ID is same as 'Pre-Mitigation Production MCU', err......my condolences.

It is very strange that biloxee doesn't encounter this issue for his win10.

Oh?
Now this is strange indeed.
Can you check if your laptop has temperature issue?

https://cpuid.com/softwares/hwmonitor.html
Run TM Speedtest and report back 'Max' value.

Cause there was a user who first only got 200-250Mbps, then after I dealt with the microcode issue, speedtest increased to 500-580Mbps.
Further testing revealed his CPU is overheating at 100'C = resulting in CPU throttling. Intel CPU will start throttling after reaching 100'C.
He blasted a table fan directly to the mainboard area and somehow able to keep CPU temp below 100'C, voila 800Mbps on speedtest.

What is the peak sustained CPU frequency during DL on speedtest?

edit:
Cause laptop power management is different than desktop.
BIOS could limit your CPU frequency.
If you on battery, certain manufacturer actually set lower 'turbo boost' bins compared when power plug is connected.

edit2:
Do you ever get constant turbo frequency of 4.1Ghz during TM speedtest download?

Hmm? Have you set C1200 5ghz channel width to 80Mhz only?

You sure? I am somehow skeptical because the speedtest kinda weird. What is the wifi link speed? (don't confuse this)
Next would be enabling 5ghz beamforming....which only available on EU firmware....

Other than that, nothing much you can do for wireless performance.

As for your downloading......are you seriously torrenting on IDM?

Best condition = you can get 480Mbps via 5Ghz wifi

Wifi link speed also don't know = https://www.tenforums.com/tutorials/75371-s...ndows-10-a.html

Your C1200 is using Malaysia firmware = give up on beamforming. Beamforming only available with EU region firmware. Your adapter supports beamforming by default. Your c1200 router.....sigh...

Nothing wrong with your T9UH, just orient the antenna correctly.

-.- You don't even know how you download the movie? DDL or BT? Even DDL server also can resume if server supports it.

Nothing wrong with router and adapter. Everything is normal.
Guess 280mbps down, 170mbps up are your best case with current combination.

The torrent or DDL on the other hand, you gotta solve it yourself.

Are you serious?
If you change the power profile to high performance, can it get at least 4.1ghz on any one of cores? (Hwmonitor)
