I've been getting high pings very intermittently along with VERY slow speeds 1-3 mbs D .2 U. Any sort of online game has now become unplayable. Modem has been logging these errors about 12 hours apart from each other for the past 10 days now. Does anybody know whats going on?
Started Unicast Maintenance Ranging - No Response received
No Ranging Response received - T3 time-out
Have you checked your signal levels?
Yes, everything else is cool. From what I can gather on google, nobody seems to know whats causing the modem to log these error
It seemed to straighten itself out for a while this morning, however I've got a new one this afternoon:
SYNC Timing Synchronization failure - Loss of Sync
and then back to the same behavior. Anybody any thoughts? I have a tech coming on Thursday.
Do a Line quality test at www.dslreports.com ---> tools --->line quality test. You might have to get a free account setup to do the test? It will flag their bad network routers. Some are there's so are others they lease. They lag at fixing these!
You may just be looking at ICMP de-prioritization..
And they don't lease 'em. Even though they have built out their own transit backbone, they still purchase/are a consumer of upstream bandwidth.
