Hey everyone,

I’m hitting a wall trying to figure out why Shadow PC is stuttering and freezing on my gaming tablet when my local internet line seems completely fine on other devices.

I ran the official Shadow speed test (speedtest.defra01.shadow.tech) on both my work laptop and my gaming tablet (Lenovo Y700) using the same 5 GHz Wi-Fi network right next to my router, and the results are night and day:

Non-Tablet Device (Work Laptop):

• Download: ~400–500 Mb/s
• Ping: Flat ~28 ms
• Jitter: Extremely clean at ~4 ms

Speed test ran on work laptop at speedtest.defra01.shadow.tech

Gaming Tablet (Lenovo Y700):

• Download: ~300 Mb/s
• Ping: Spikes up to 80+ ms
• Upload Line: Almost flatlined at 0 Mb/s
• Jitter: Spikes wildly between 100 ms and 270+ ms

Because of this, Shadow PC has micro-freezes/input delay on the tablet, even though the laptop gets a smooth stream on the exact same network.

Everything I’ve tried so far to fix it:

1. Offloaded Home Network Devices: Turned 2.4 GHz back on, disconnected background devices, and verified that heavy devices (like my Fire Stick) were turned off so the tablet had clean airtime on 5 GHz.
2. Turned Bluetooth OFF: Completely disabled Bluetooth on the tablet to prevent antenna-sharing interference on the Wi-Fi card.
3. Android Location Services: Turned off background Wi-Fi scanning and Bluetooth scanning under Location settings.
4. MAC Privacy Settings: Changed the Wi-Fi network privacy setting from "Use randomized MAC" to "Use device MAC".
5. Legion Zone / Software Features: Disabled all network acceleration/fusion features in the tablet’s software.
6. Router Tweak Attempts: Checked the BT Smart Hub 2 router settings, but because of BT's 'forced band-steering/firmware' , I can't split the 2.4 GHz and 5 GHz network names separately without throwing errors on client devices.

Despite all of this, the laptop maintains 4 ms jitter, while the tablet continues to hit 270+ ms jitter and an upload drop on the speed test graph.

Since the test results on the laptop seem flawless compared to the tablet on the exact same Wi-Fi, the network itself seems fine. I'm not particularly good at networking stuff, so I really want to avoid spending money on a dedicated Wi-Fi 6 Access Point if the router isn't actually the root cause, especially if buying extra hardware won't even fix what might be a device-specific Android or Lenovo issue.

Note: Using an ethernet cable on the tablet is NOT an option for me

Thanks in advance for any advice!
