I move from a rent modem to this one . it be easy to setup and I could use it right away . since I already check if the modem be compatible with the network provider -lrb- Charter -rrb- , it might have help I . of course , I do not see much spike in speed after move to DOCSIS 3.0 modem , but it might be due to Charter not provide speed of DOCSIS 3.0 . I also do not have the problem of restart the modem . hopefully it do not throw new surprise . ; - -rrb-
