In short
What this service changes
Three things first, the detail below.
Ethernet test first
It separates a Wi-Fi problem from a connection problem in about a minute.
Private Relay caps throughput
Routing through Apple's proxies is a common and easily missed cause.
VPNs and tracking limits
Both add hops that show up as slower downloads on an otherwise healthy connection.
Key takeaways
Key takeaways
Test wired over Ethernet first. If the wired result matches your plan, the bottleneck is Wi-Fi and not the Mac.
If wired speeds are slow too, the fault is upstream - the ISP, the modem or the cabling in the building - and no macOS setting will fix it.
iCloud Private Relay routes traffic through Apple's proxies and can cap download speed. Turning it off is a one-setting test.
A VPN, or the Limit IP Address Tracking toggle, throttles throughput the same way and should be off while you test.
Band choice decides the ceiling: 2.4 GHz reaches further but caps speed, while 5 and 6 GHz carry a full plan when router and Mac both support 802.11ax or be.
Changing DNS to 1.1.1.1 or 8.8.8.8 fixes browsing that feels slow even when a speed test reports the right number.
If that did not fix it
Wired is slow too
When an Ethernet test is also well under the plan, the bottleneck sits before the Mac: the router, the ONT or the ISP's line profile. We plug a laptop straight into the ONT's LAN port bypassing the router. If that matches the plan, the router is the limit, as ISP-issued units often are.
Run Speedtest wired to the ONT, wired to the router, and on Wi-Fi beside the router, and send the three numbers with the router model on WhatsApp. If the ONT itself is slow, that is an ISP ticket, and we tell you what to say to Etisalat or du to keep the call short.
Test in this order
Wire it up first. Everything else is a guess until you do.
Run a speed test over Ethernet with a USB-C adapter before changing a single setting. If the wired result matches what you pay for, the Mac and your connection are both fine and what you have is a Wi-Fi problem — router placement, which band you are on, or the standard your router supports. That one test removes most of the guesswork and stops you troubleshooting the wrong machine.
If wired is fine and wireless is not, the usual culprits are software rather than radio. iCloud Private Relay routes traffic through Apple's proxies and can cap throughput noticeably. VPNs and IP-tracking limits do the same. Changing DNS to a fast public resolver often helps, and renewing the DHCP lease clears a surprising number of odd cases. If wired speeds are slow too, the problem is upstream of the Mac entirely and belongs with your provider or your router.

The full answer
Plan says 1 Gbps but Speedtest shows 80? Here's how to find the bottleneck.
If your Mac M4 is downloading slower than expected, test in this order. 1) Run Speedtest while wired via Ethernet (USB-C adapter). If the wired result matches your plan, it's a Wi-Fi issue - check router placement, 2.4 vs 5 vs 6 GHz band, and 802.11ax/be support. 2) Change DNS to 1.1.1.1 or 8.8.8.8 (System Settings → Network → Wi-Fi → Details → DNS). 3) Disable iCloud Private Relay (System Settings → Apple ID → iCloud → Private Relay) - it routes via Apple's proxies and can cap speeds. 4) Turn off VPNs and any "Limit IP Address Tracking" toggle. 5) Reset SMC / NVRAM (Apple silicon: full shutdown, 30s wait, restart). 6) Renew DHCP lease in Network → Details.
If wired speeds are also slow, the problem is your ISP, modem, or in-home cabling. We troubleshoot Etisalat / du connections and provide WiFi installation across Dubai.
If other devices on the same network download at full speed and only the Mac lags, the fault is in the Mac; see MacBook WiFi repair.
From the bench: what we see with this one
The M4 MacBooks have Wi-Fi 6E, and most routers Etisalat and du hand out are Wi-Fi 5 or Wi-Fi 6, so the 6 GHz band the Mac is capable of is never used. In villas the ONT usually sits by the front door and the router is wherever the engineer could reach, often twenty metres and two concrete walls from the desk. The 5 GHz signal through that is the real cap, and no setting on the Mac changes it.
The other thing we find constantly is the adapter. A USB-C hub with a USB 2 internal hub limits its Ethernet port to under 480 Mbps, and a hub driving a 4K monitor shares its bandwidth with the network port. A plain USB-C to Ethernet adapter, or the 10 Gb port on a Thunderbolt dock, tells the truth about the line.

Find the bottleneck
Wi-Fi problem or ISP problem
One wired Ethernet test separates the two, and it decides whether anything on the Mac is worth changing.
| Wi-Fi or Mac settings | ISP, modem or cabling | |
|---|---|---|
| Wired Ethernet test | Matches the speed on your plan. | Slow over cable too. |
| Speed around the home | Drops with distance and through walls. | Equally slow in every room. |
| Other devices | Some are fine, others are slow. | Every device is slow at once. |
| What to check first | Band, router placement, Private Relay, VPN, DNS. | Modem, the line into the building, in-home cabling. |
| What actually fixes it | Settings changes, or a survey and a better access point. | Etisalat or du need to test the line first. |
