CM1150V LACP LAGG Firmware Issue - Comcast V2.02.04 and V2.02.03
Anyone else notice issues with the Netgear CM1150V running on Comcast with the V2.02.x firmware? Particularlly with LACP/LAGG (IEEE 802.3ad) Ethernet Port Aggregation Enabled? I have noticed this...
I'm having the same issue here, still v2.02.04 of course. Ended up disabling LACP on both sides, we'll see how that goes.
I had contacted Netgear for a warranty replacement, since I was having the issue since the beginning, and have tested/swapped literally everything between the tap block (on the pole - Comcast tech even ran a new drop from the tap) and the computers (wiring, new runs, etc.) I came to the conclusion that it's either an issue with the modem itself, or something upstream from the tap block on Comcast's infrastructure. When I got the replacement modem, I remember pretty specifically not enabling LACP on the replacement, but still had the slowdown - it did take a few days before the first time it occurred, but now it's back to <24 hours.
For those suggesting other modem models, please remember that some of us actually do need the voice ports. I actually have two active landlines (one for me, one for my mother-in-law), so a non-voice modem isn't an option.
So I was also having issues with the V2.02.04 firmware that Comcast pushed to my modem when I first installed it. I was running through an RAX80 at the time and every 4-6 hours DL would drop to 40Mbps and UL would stay at 40 Mbps. I had the techs here and they said all is good with the signal strength and modem behavior as far as they could tell.
I was waiting for a firmware patch like everyone else. I ended up swapping the router out to the RAX120 since it has more wireless streams for my multi-tasking gamer kids and a Multigig port to connect to my SX10 switch. I am almost certain it is coincidental but ever since I put the new router into the network setup I have been just under DL 1200 Mbps without needing to power cycle the modem every 4-6 hours. When I check the modem it now says firmware V4.02.02. Has anyone else seen this version firmware pushed to their modem by Comcast?
Just for reference my RAX120 router firmware is V1.0.0.78.
HypaspazzLooks like I'm still on v2.02.04 myself. I did disable LACP (on both sides of course - the modem and my router [a Dell PowerEdge server running Netgate pfsense]), and that resolved it for me - I have not had reduced bandwidth ever since, and it's been at least a couple weeks since I last rebooted the modem.
to be sure that modems get a change to update FW from the ISP, power OFF the modem for 1 minute then back ON. Some ISPs will auto push FW to modems during this power cycle. If not, contact the ISP and ask them to update.
FURRYe38 Indeed, I know I'll need to reboot and have not done so yet; however, if Comcast has finally updated the current firmware on their side, I'll give it a shot soon!
Also, total off-topic but wondering because I keep seeing your username over here...are you a furry? :3
