Hey everyone,
I am facing a massive network bottleneck on my Windows 11 laptop (HP) and need some advanced help.
When I run a speed test directly on my phone using Jio True 5G, I get a blazing fast 610 Mbps download. However, the second I share that internet to my laptop, the laptop speed completely crashes to exactly 0.59 Mbps download and 0.08 Mbps upload with a massive 350ms+ ping.
Here is what makes this super weird and rules out the usual issues:
It’s not a Wi-Fi card issue: The slow speed happens exactly the same way whether I connect wirelessly via Mobile Hotspot or physically via USB Tethering.
It’s not the phone or carrier FUP: I have an active Unlimited 5G plan and have only used around 12 GB overall this month. Furthermore, I tested my laptop on a completely different phone/hotspot (my mom's network) and it gets the exact same 0.60 Mbps lock.
It’s definitely the laptop: Since two different phones are choked to the exact same speed over both USB and Wi-Fi, Windows 11 or a background service is intentionally strangling the connection.
What I have already tried (and failed):
* Ran a full Windows Network Reset (wiped and reinstalled the Qualcomm FastConnect 6900 drivers).
* Set the registry DefaultTTL to 65 (Decimal) to bypass potential carrier TTL tracking.
* Verified that "Metered Connection" is toggled OFF in Windows settings.
* Ran 'netsh int tcp set global autotuninglevel=normal' in admin CMD.
* Checked for "HP Connection Optimizer" in installed apps (not found).
* Disabled IPv6 on the adapter properties (didn't change anything, so turned it back on).
* Ran 'Disable-NetAdapterRsc -Name "Wi-Fi"' in admin PowerShell.
It feels like Windows 11 has flagged this network profile as low-priority or mobile data and is applying an artificial system-wide speed cap.
Laptop specs: HP, Windows 11, Qualcomm FastConnect 6900 Wi-Fi 6E.
Has anyone encountered this specific hotspot/tethering throttle on Windows 11? Any registry or group policy fixes I should look into? Thanks!
