... is there any point to this if the Billion is going to be replaced?
Probably not, but something here is way off, and something a simple as a faulty cable might be an easy fix.
Searching the internet, indicates that some retailers were quoting the EWAN to LAN path as capable of 600Mbps in their sales literature, but more commonly users are reporting the throughput limits somewhere around 400Mbps (and therefore not restricted by 100Mbps ethernet ports).
Based on available test reviews and discussions regarding the Billion BiPAC 7800DXL, the maximum throughput from the EWAN (Ethernet Wide Area Network) port to the LAN (Local Area Network) ports is approximately **400 Mbps**. This figure comes from user reports and tests shared on forums, such as the Billion UK Forum, where a user with a gigabit uncontended line reported achieving transfer rates of around 400 Mbps when using the 7800DXL as a router with the internet connection routed through the EWAN port to the LAN ports. Another contributor confirmed that their testing showed an average EWAN throughput of around 400 Mbps for the 7800DXL, suggesting this is close to the device's practical limit under typical conditions.
While the 7800DXL is equipped with Gigabit Ethernet ports (capable of 1 Gbps theoretically) and is marketed as supporting high WAN throughput for fibre connections, real-world tests indicate it doesn't fully reach gigabit speeds from EWAN to LAN. For comparison, when the same user bypassed the router and connected directly to their PC, they achieved approximately 970 Mbps, highlighting that the 7800DXL's hardware or firmware imposes a bottleneck, likely capping at around 400 Mbps in this configuration.
No higher throughput figures exceeding 400 Mbps from EWAN to LAN were consistently reported in accessible reviews or test data for the 7800DXL. This suggests that, despite its Gigabit-capable ports, the router’s processing power or internal architecture limits its maximum throughput to this level under typical test conditions. If you're seeking higher speeds, a more powerful router might be required, as noted in some discussions.
Anyway, I give up as this discussion is going nowhere !
