That can cause random disconnects, spontaneous re-booting of the modem, speed, packet loss, and latency problems.
In a self troubleshooting effort to try to obtain better connectivity / more wiggle room, check to see if there are there any excess/unneeded coax cable splitters in the line leading to the modem that can be eliminated/re-configured. Any splitters that remain should be high quality and cable rated for 5-1002 MHz, bi-directional, and no gold colored garbage types like GE, RadioShack, RCA, Philips, Leviton, Magnavox, and Rocketfish from big box stores like Home Depot, Lowes, Target, Wal-Mart etc. Splitters should be swapped with known to be good / new ones to test
If there aren't any unneeded splitters that can be eliminated and if your coax wiring setup can't be reconfigured so that there is a single two way splitter connected directly off of the drop from the street/pole with one port feeding the modem and the other port feeding the rest of the house/equipment with additional splits as needed, and you've checked all the wiring and fittings for integrity and tightness and refresh them by taking them apart then check for and clean off any corrosion / oxidation on the center wire and put them back together again, then perhaps it's best to book a tech visit to investigate and correct.
I have problem a month. They call me and I upgrade my speed from 300 to 600 . I never get 300 or 600 .I call Xfinity and they send tech . He check every and he say maybe the cable rooter is not good and he check the speed and it was 1000 .i call netgear and after some test they send me new one . When I get the new one I have same problems . Netgear call me to make sure everything is good and I say to them no . They run some test ad they found the downstream channels power level is too high above 7 and they should be-7 to 7 . They asked me to call xfinity again and ask them to check the power levels at the downstream channels . I call xfinity and they say this is setup like that and when the send the signal is automatically send high power level . She told me to send tech again and I tell her they send tech before and he say everything is good . She say then you be better to go to your old speed 300 . So they put me to the old speed but still have problem . Netgear call me back and they ask me if xfinity fix the problem . And I say no . I don't know what phone number to call to get fix this . I chat yesterday with xfinity agent and he say they will call me from xfinity advance support in 20 min max . Is be 1 day and nobody call me . All this to me is crazy... how hard is to fix those channels power leves .....?????
