Windows 10下WiFi与LAN桥接问题
Hey there, let's work through this bridge connection issue together! It's definitely frustrating when you expect combined bandwidth but only get the speed of one connection. Here are some troubleshooting steps to try:
First, double-check your bandwidth testing method: Windows network bridges use load balancing based on destination addresses, not simple bandwidth stacking. If you're using a single-threaded download to test speed, it will only use one of the two connections. Try a multi-threaded download tool (like IDM, or enabling multi-threaded downloads in your browser) to see if you get the combined speed you expect.
Verify each connection's speed individually: Before blaming the bridge, make sure both your WiFi and USB tethered LAN are still hitting their full 8 MB/s when used separately. Sometimes the USB tether might have driver glitches or your phone's tethering settings could have changed—test each one alone to rule out individual connection issues.
Reset the bridge configuration: Corrupted bridge settings are a common culprit. Delete your current bridge by right-clicking it in Network Connections and selecting "Delete", then re-select both adapters, right-click, and create a new bridge. Wait for Windows to finish configuring it (it might take a minute) before testing again.
Check adapter binding order: Windows might be prioritizing one adapter over the other, leaving the unused. Press the Alt key in Network Connections to bring up the menu, go to Advanced > Advanced Settings, then in the "Adapters and Bindings" tab, make sure both your WiFi and USB LAN are listed under the bridge, and the bridge is set as the top priority if needed.
Disable QoS bandwidth limits: Windows sometimes reserves bandwidth for system use, which could cap your combined speed. Open the Local Group Policy Editor by running
gpedit.msc, navigate to Computer Configuration > Administrative Templates > Network > QoS Packet Scheduler, find the "Limit reservable bandwidth" setting, set it to "Disabled", then restart your PC.Rule out third-party software interference: Firewalls, antivirus tools, or VPNs might be blocking the bridge's traffic. Temporarily disable any such software and test the speed again to see if that's the issue.
Hope one of these steps gets your combined bandwidth working as expected!
