CGN3ACSMR League of legends lag after firmware update

Hello, unfortunately I'm having issues again with  Rogers again. I was one of the many who had the firmware update applied to my modem a few weeks back, which did, however, fix the firewall issues with league of legends. But now I am getting very annoying lag during games I play. Wireless or wired directly to modem, I get ping spikes that fluctate up to 350 every 30-60 secs making the game no fun. I can't say when this issue started because it's been happening ever since the firmware update, and probably even before that. I say probably, because before the update, i would use a vpn to connect to the league of legends, and i assumed it was the vpn that caused the lag, apparently not. So I contacted Rogers yesterday, they said my cable signal is low, a technician came in today and fixed that for me. But the problem still continues. Once again, wired or wireless, happens either way...'ve downloaded this Inssiderhome app, and im not too sure what it does. My signal is -70 dbm, link score changes between 80-100, 0 overlapping, 0 co-channel, max rate is 526, ac and the channel is 36. Below is my downstream and upstream overviews.

Re: CGN3ACSMR League of legends lag after firmware update

Are those downstream levels after the tech has completed his work?  I hope not!!  You have a couple of problems on the go.  Your cable signal levels on the downstream side are all still very low.  They should be at 0 dBmV, where yours are averaging around -10 dBmV.  The signal to noise ratios are fine.  Usually they are in a 36 to 40 dB range.  The upstream side isn't too bad.  They are normally in the 36 to 40 dBmV range.  So, it looks like you have a cable issue, my guess is aging of the external cable or connectors.  Call tech support and have the CSR run another signal check on the modem again.  The result of the discussion should be another tech visit to your home to check out the cables and their connectors.

 

In terms of the wifi, if you have -70dBmW as a received power level, thats not good.  Ideally you should be up in the low -40s range with everyone else in the low -80s and ranging below that into the -90s.  Have a look at channels 149 and higher.  If there are empty channels there, switch to any of those channels as they have higher allowable power levels and set the modem to run 20/40 Mhz wide channels if that is selectable.  Are you running a laptop at some distance from the modem?  Just wondering as these modems are not noted for steller wifi performance.  If you can reposition the modem somewhere else it might help.  It just depends on the layout of your home, where the modem is located, your typical operating range to the modem and what happens to be in the way, ie. wood of concrete walls.  You might want to start considering a third party router with external antenna to see better wifi performance. 

 

First things first, call tech support and let the CSR know that your downstream levels are still very low and start this process over again.

Re: CGN3ACSMR League of legends lag after firmware update

Alright so..I contacted CSR again, they sent a technician today, who couldn't figure out the problem from the inside of the home.He said he was going to try to do something from the outside, and if it didn't fix the problem i'd have to swap modems, as this one may faulty. So once he did whatever it was that he did, the signal strength didn't get any better..so I went and swapped modems. Got the same modem again, the newest version....CGN3ACSMR. So the signal strength with the new modem is still the same, in the -10s.however league game are not lagging anymore. Got a solid ping of 72 for the first 30 minutes of testing. I'll repost after more testing but so far it works fine, and i guess the modem was the problem. Don't know about the signal strengths.

Re: CGN3ACSMR League of legends lag after firmware update

When you were conversing with the CSR the second time around, was he or she able to pick up on the low signal levels at the modem?  Did the tech indicate that he was going to elevate this to a maintenance issue if he could not find the problem?  And....are you in a house, condo, apartment, etc....  Just wondering.

Re: CGN3ACSMR League of legends lag after firmware update

Unfortunately I wasn't home, I talked to him over phone, and all he said was the cables from the inside all seem fine. He said he would try one last thing on the outside and if that didn't fix it, I'd have to exchange modems. He called me from a private number, so I wasn't able to call him back when i got home, but whatever he tried from the outside didn't fix anything. I'm in a house.

Re: CGN3ACSMR League of legends lag after firmware update

Here is something you could try just to check out the signal levels for the cable when it enters your home.  I'm assuming that you might have a splitter on the cable that comes in from the street if you have more than one Rogers service.  Take your modem and connect it to that incoming cable by removing the splitter.  Fire up the modem and check the same downstream and upstream tables to see what those levels are like, right where the cable enters the home.  If there is no change, then the problem is definitely outside the home.  The question is, what are the tech's going to do about it.  The only thing saving you from really terrible service at the moment is the fact that your signal to noise ratios are good.  If not for that you would see slow data rates and probably interruptions in service.  So, personal opinion, a call to tech support is in order to determine what is going to be done to resolve the problem.  You can't stay at those levels as they will only get worse.   If you are seeing issues with your internet service or any other service, call tech support.  Put them on Speed Dial.  Make sure that they are logging the issues as they come up, whether its every hour, every day, etc.

Hello @gaggan07,

 

Thank you for updating the Community with the progress in resolving the signal issues, swapping the modem out will not help in signal improvement. We can definitely further investigate and help resolve the issue. I would have a specialist contact you through CommunityHelps.

 

Regards,

RogersMoin

Called Rogers again, and this time they said they will send a "senior technician" on thursday. Maybe he will have an idea of what to do.

Re: CGN3ACSMR League of legends lag after firmware update

If you're around when the tech is trying to resolve the issue, and the tech has come to the end point of the troubleshooting, if its successful, hurrah, if not, the question that you should be asking right then and there is, "Whats the next step".  Personal opinion the answer should either be a return visit the next day, or, its elevated to a maintenance crew, and if that's the case, who do you contact in order to find out what the intentions are.  Don't let the tech leave without informing you of the next step and also a point of contact.  If for any reason that can't be done, ie. you're not around during the tech visit and you can see that there is no resolution when you return, please pm RogersMoin the details.
