Re: Surge Protector
So my question is should the modem always be plugged into a wall outlet for best performance or is it ok to use a surge protector even if you have no noticeable issues? How about for the 2 in 1's? When the technician asks to bypass everything they dont care whether I use the top or bottom outlet on the same duplex receptacle and whether or not the other outlet is in use by say another modem, router, or surge protector with many devices on it as long as just the modem is direct into some sort of wall plate outlet? Just want to make sure its getting max power and all because I read that using surge protectors or any kind of power splitting similar to cable splitting isnt recommended even if you aren't experiencing any issues and that most likely the modem/router has a built in surge protector of sorts and you'd get max power from both modem, router, or 2 in 1 if everything is direct which could see improvements. No guides really cover this they just say bypass and plug into the wall but never mention anything further I just wanted to make sure that its not like they want the modem into one outlet and the other outlet top or bottom to be free and if i say had a router then to plug it into a different wall plate also by itself on either the top or bottom with the other not being used. Is there a list of internet related devices that should be direct to wall for best performance and benefit and do not need surge protection as it is either built in or hinders the device by splitting or sharing an outlet to many devices? Some examples would be modem, router, gateway, laptop, etc..16Views0likes0CommentsSurge Protector
I have a question support always requests that all surge protection or multi power outlet/power strip/bars are bypassed and the modem/router/gateway 2 in 1 directly plugged into the wall outlet/plate. My question is normally a wall outlet/plate has already 2 plugs that it can be inserted into top or bottom my question is there isnt a difference between using top or bottom and whichever you use can the other be used as well by maybe say a power strip? Just looking at what grants the best most stable power to the modem/router/gateway 2 in 1 device. Mostly asking cause all the diagrams just show the 2 in 1 being plugged into the bottom outlet of the wall plate wall outlet and the top being empty. Always wanted to get a straight answer on when bypassing like how much is necessary and how much will definitely rule out electrical stability. Thank You2.5KViews0likes3CommentsFrequency

Reason I am asking is because I notice lately the downstream channels are all in the 300mhz to 400mhz ranges instead of the usual 900mhz range. No issues with service just wondered why the change and what it meant? No splitters amplifiers or attenuators just a straight single one outlet line from underground street sidewalk to side of home as direct as you can get. They never say anything about frequency just power snr QAM. Also signal levels look ok? I noticed upon reboot of unit it connects in the 900mhz range on the downstream with the power levels closer to 0 but the snr at 35 the Upstream drops within a few minutes on the first channel to 0 and a partial service message is given on the Upstream and it makes a power adjustment to that 300mhz frequency on the downstream from 900mhz. Hopefully it's not an issue. Please let me know thanks. I have seen em in my area a lot lately the techs. Service is fine though.6.6KViews1like1Comment- 0Views0likes0Comments

Re: Signal level question
Strange because here it shows that it is approved for cox at that version: https://kb.netgear.com/000036375/What-s-the-latest-firmware-version-of-my-NETGEAR-cable-modem-or-modem-router No need to worry though because there was a maintenance at midnight almost 2 hours ago and the version went to V1.01.05 from V1.01.04 so it looks like the field techs got it automatically without any necessary intervention. I guess it was a good time to do a swap. I know the latest version addressed the security vulnerability and what not. Looks like we are all good otherwise just assuming the right model CM MAC and serial are on the acct. However it is provisioned it is working fine and I'm sure the rep got the correct digits. The self activation VLAN never works always have to call it in. Thank You So far I am happy with the swap and am noticing the difference between going from an 8x4 D3 to a 16x4 D3. Granted I'm in a maintenance window right now that has restarted the net 3 times including the firmware update but the IVR said there would be work being performed for 90 mins up to 6 hours from 12a-6a and to expect this otherwise it was perfect all day and evening. I know they are discontinuing a lot of the old legacy modems soon. My guess is preparations for this and service improvement. The signal levels don't look too bad normally its bonded from channel 17-32 at the highest frequency and mostly 0 dbmv for all downstreams ups around 40 on all chnls.

@ChrisL Thanks for the reply so the CM500 would be like the above poster said as in great for my service? Also can you check and see if my current mac model sn is correct along with firmware version? I have the CM500 now I switched it out and I believe on netgear's site it says for the CM500 the latest cox approved firmware is V1.01.05 but my modem at 192.168.100.1 says it is running V1.01.04 Any way you can push it to my modem the latest and greatest and check on the mac model and sn? Thank You10Views0likes0Comments- 12Views0likes0Comments
