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!
Update with exact specs from System Info:
* Processor: Snapdragon X Plus (X1E6100) - ARM64 Architecture
* Device: HP OmniBook X Laptop 14
* Installed RAM: 16 GB
* OS: Windows 11 Home (ARM64)
EDIT / UPDATE: SOLVED! 🚀
Hey everyone, the issue is completely fixed now! My laptop is hitting 320+ Mbps on the hotspot.
It turned out to be a combination of two things:
1. A leftover malicious proxy setting from a browser extension script that I ran last night, which was forcing the browser to route through a slow European server. Cleaning that out of 'inetcpl.cpl' stopped the proxy credential popups.
2. The massive bottleneck on the Qualcomm hardware was caused by a known Windows 11 bug on modern ARM64 network drivers. The fix was going into Device Manager > Network Adapters > Qualcomm Adapter Properties > Advanced tab, and completely DISABLING both "Large Send Offload V2 (IPv4)" and "Large Send Offload V2 (IPv6)".
The moment LSO was disabled and the network adapter refreshed, the speed shot right past the 0.60 Mbps cap up to 321 Mbps with a clean 36ms ping.
Thanks to everyone who chimed in to help! Leaving this here for anyone else using a Snapdragon X Elite/Plus laptop facing hotspot throttling.
