I have a Balance 380 connected to an ISP that offers me 100mbps. However, the 380 will not give above 50mbps.
Furthermore, and I’m not sure how this relates to the issue, but the 380 is set to auto-negotiate and the ISP is set to 100 full duplex. If I change the 380 to 100 full duplex, the connection drops completely - “no cable detected”. I have tried all permutations, including setting the ISP side to auto, which also gives only 50mbps.
If I connect a Windows PC direct to the ISP and set the NIC to 100 full duplex, I can connect at 100mbps, so I know the ISP is carrying the advertised speed on their side.
Firmware is 5.4.7 build 2423
Any thoughts on what may be causing this issue?
