Snel internet op iPhone, traag op MacBook Pro

[gpweston]

I am getting 100 Mbps on my iPhone, only 10-30 Mbps on my MacBook Pro.

Consistently the iPhone is performing as expected and the Mac really slow.

• Which type of modem do you use?
• Is other network equipment being used in conjunction with the modem?
• Is the MBP connected using ethernet or Wi-Fi?
  In case of Wi-Fi: is it connected on the 2.4 or 5 GHz frequency band and what is the current link speed? Wireless Diagnostics may be used to reveal this information.
• Is VPN, antivirus or firewall software active on the MBP?
• Could you run a RealSpeed test on the MBP?
  (RealSpeed is not available for the Compal CH7465 or when the modem is in bridge mode.)

Hi.

 - The regular ziggo white modem/router

 - Tends/NOVA Wifi mesh boxes

 - Varies, but the speed issue is the same regardless

 - No VPN, antivirus or firewall

 - Route download is 124Mbps Device 27Mbps

Assuming your subscription is Internet Basic/Lite, the full subscription is available on the modem router.

• Has AP/bridge mode been configured on the Tenda Nova units? See MW6-How to set AP mode-Tenda US for additional information.
• Does connecting to the modem's built-in ethernet/Wi-Fi make a positive difference?
• Just to be sure: whatismyipaddress.com reports 'Ziggo B.V.' as ISP?

 - AP/Bridge mode is not configured.  It is "Dynamic IP"

 - IP address does report Ziggo BV

 - Connecting direct to the built-in wifi does not help.

The Tenda/Nova units should be configured in AP/bridge mode with the modem in router mode (white status LED). However, the fact that connecting to the modem directly does not improve the speeds already rules this out as a potential culprit.

In two previous topics (Significant Lag in Gaining Internet Signal (Macbook Only) + Trage wifi-verbinding op MacBookPro (macOS Sequoia 15.0)), disabling macOS's automatic proxy discovery resolved a similar problem. See Change proxy settings on Mac - Apple Support for additional information.

So bridge mode is on now.  No change. 

Checked automatic proxy discovery is off.

I'm on Ventura 13.7.4 and this seems to be the latest this Mac will take.

I have a 2015 Macbook Pro on High Sierra and a 2022 M2 MacBook Air on Sonoma and they both get the same speed internet as the router.

So it is definitely just this device.  Any ideas what I else I could check?

Does the problem persist when you connect the MBP in question to a different network, such as your iPhone's mobile hotspot?

So... I shut everything down - ziggo router, nova boxes, MacBook.  Then brought them back up slowly.  Now the internet speed on the MBP matches the router.  The only change that remained was the bridge mode.  So it looks like that was the cause but only affecting one machine.  Weird, but now fixed so thank you very much !
