I've got a 15Mbps DSL connection but can't get anything better than about 4.5Mbps throughput. I've tried different cables but that hasn't helped, currently plugged directly into the modem.
It's possible the modem is on the way out, in which case, what's a good replacement? Something that can be bridged to PPPoE (so my good router can do NAT duties) would be nice but I don't fancy my chances.
Any other suggestions on things I could check? The current modem is a DSE unit which is a rebranded TP-Link TD-8840 which has been great in the past (Broadcom based).
