Since we moved house (over a year ago) our 200Mbps is nowhere near as good as it was. We only moved a few streets away, but it was from a new estate (with brand new VM infrastructure) to an older house. We have a SH3 in router mode (pending arrival of a new IPFire/pfSense box), with the wifi disabled (we have a Ubiquiti AC PRO) and the firewall and flood detection disabled.
All LAN devices are running either Intel Pro 1000 gigabit NICs or else wireless AC (on 5GHz with 80MHz channel width). Operating systems include Windows 10 x64, macOS Sierra and various Linux and BSD derivatives (mostly openSUSE Tumbleweed).
According to the CMTS MAC it's Cisco kit, and we only have 8 downstream channels (256QAM) and 2 upstream channels (16QAM). At our previous address we had the full complement of downstream channels and four 64QAM upstream channels. Our speeds and page loading problems are getting worse and worse overall, but it does hit full speed off-peak which leads me to wonder about congestion rather than just old/knackered VM kit.
Incidentally, I was told by VM that Homeworks+ was not available (likely the old Cisco CMTS?) but I could have the VIVID200 Gamer. We could really use the extra upload so I'm going to see what retentions can do next week.
Generally speaking, speeds are all over the place, and I get a lot of 'site couldn't be found / site timed out' errors even on the 'big' fast loading sites. I tried with Google, openNIC and other DNS and a clean browser (no AV, no addons etc) but no change - so it's not a DNS issue. It affects page loading, YouTube (which buffers or stalls a lot) and download speeds for NNTP, P2P, FTP and HTTP vary between 500KB/sec and 10MB/sec. I used to see 20MB/sec consistently but over time this has fallen to the variable mess we have now.
Can anyone please double check our stats (and account, for VM staff) and let me know if anything looks amiss or if our area (Liverpool L11) has congestion or network kit issues? Many thanks.
