2.4 GHz Wi-Fi reaches further, 5 GHz is faster up close. The signal-loss calculation between bands, the channel count in Belgium, the 6 GHz band of Wi-Fi 7 and the five kinds of device worth putting on the right band. Checked on 20 October 2026.
CGNAT makes several subscribers share one public IPv4 address: browsing works, remote access does not. A five-minute test, what public sources say about Proximus, Orange and VOO, and how to get out. Checked in Belgium on 12 October 2026.
FTTH, FTTB and FTTC are not the same fibre. Only the first one reaches your home. The difference, the speeds actually sold in Belgium (checked 10 October 2026), where coaxial cable fits, and how to tell what reaches your address.
Since 1 November 2024, Belgian law allows you to replace your operator's box with your own router. What that means in practice at Proximus, Telenet, Orange, VOO and Digi, the double-NAT trap, the real budget, and the two cases where you should leave things alone.
A strict NAT blocks the inbound connections an online game needs, on PS5, Xbox and Nintendo Switch. IP reservation, UPnP, port forwarding, double NAT: the method in order, and the one case, CGNAT, that no router setting will ever fix. Checked in Belgium on 26 September 2026.
The ONT turns the light arriving through the fibre into an Ethernet signal, and its generation decides which plans you can actually order at your address. Prices checked on 20 September 2026 on the Proximus catalogue, a GPON versus XGS-PON table, and what to do when a light goes out.
Before you call your provider, six steps in order to find out whether the slowness comes from the line, the router, the Wi-Fi or the device. With a table of times and equipment, and what a technician visit costs when the fault is inside your home. Rates recorded on 18 September 2026.
Five categories on the shelf, one question that settles it: what is the fastest port on your router? Belgian router ports recorded on 10 September 2026, a table of speeds and distances, and the cases where paying for a higher category buys you nothing.
Ping measures a round trip in milliseconds, jitter measures how steady it is, packet loss counts the data that never arrives. Three different quantities, three different thresholds, and a physical floor I calculated from Belgium: 4.5 ms to Frankfurt, 87 ms to Virginia. Figures and sources checked in August 2026.
The number your speed test displays rarely measures your subscription: it measures the weakest link between the test server and your screen, and that link is almost always inside your home. Here is why, what each link actually lets through, the method BIPT recommends for building evidence, and the four speeds written into your contract that nobody reads. Verified August 2026.
One dead room, three shelves in the shop: Wi-Fi extender, powerline adapter or mesh kit. The criteria that actually decide, a side-by-side comparison, the Belgian three-phase trap, what Proximus, Telenet, Orange and VOO rent out, and the cases where you should buy nothing at all. Prices checked on 22 August 2026.
Your plan advertises 1 Gbps but your download tops out at 110 MB/s? That is normal, and it is not a scam. The conversion rule, an Mbps-to-MB/s table built on the speed tiers actually sold in Belgium, real download times for a film, a game or a console update, and how much speed you genuinely need. Figures recorded in August 2026.
