Malo Posted January 7, 2017 Posted January 7, 2017 My isp is RCn cable. model of modem is arris CM820A. I've tried everything from turning off for 30 seconds waiting and turning back on. I have access to the Duma control panel and tried to set it to the mac of my old router and it's still not grabbing a wan ip. Any other options I haven't thought of would help. Thank you.
Administrators Netduma Fraser Posted January 7, 2017 Administrators Posted January 7, 2017 Hello, welcome to the forum! Theres no need to set it to a different MAC address. In most cases all you will need to do is reboot from miscellaneous settings. Do you know if you require PPPoE authentication?
Malo Posted January 7, 2017 Author Posted January 7, 2017 Hi thanks for the reply I already tried that numerous times with no success . No my router doesn't require pppoe. It's cable>modem>r1. I was using an old linksys e1200 with dd-wrt and it works fine.
Malo Posted January 8, 2017 Author Posted January 8, 2017 Called my isp to see if my modem was holding the mac of old router and to release it but no go. Looks like it's just a bad router.
Administrators Netduma Fraser Posted January 8, 2017 Administrators Posted January 8, 2017 Theres no reason you shouldn't be getting internet through the R1. To clarify you have the R1 connected via port 1 to port 1 of the Arris? If so please try connected it to port 2 of the duma, do you have internet then? When connected to the R1 can you go to command prompt on your PC and type in "ipconfig" and post a screenshot here please.
Malo Posted January 8, 2017 Author Posted January 8, 2017 Yes I had them in the right ports as my modem only has one port for internet. I also tried port two last night and still couldn't get internet. I can post a cmd when I get home from work in the next couple of hours. Only thing I noticed when I ran a cmd is that my dns was 192.168.88.1 which isn't supposed to the same as the default gateway. I tried manually changing it to 8.8.8.8, 8.8.4.4, my normal dns, and leaving it on auto. It wouldn't pull a dns it was always the same as the gateway. Also I'm on latest firmware.
Malo Posted January 8, 2017 Author Posted January 8, 2017 I noticed also my subnet mask on my old router was 255.255.252.0 while the r1 was 255.255.255.0 but I was unable to change that option.
Malo Posted January 9, 2017 Author Posted January 9, 2017 heres inconfig through wifi and this one is internet in port 2 and an ethernet in port 5 > PC. Its basically like I'm wired directly into the modem when i did it this way. so i had internet this way.
Netduma Staff Netduma Jack Posted January 9, 2017 Netduma Staff Posted January 9, 2017 Do you still have a spare router; perhaps the Linksys you mentioned earlier? If so, please post in the 1 on 1 section with dates / times you'll be available this week and Fraser will book you in.
Administrators Netduma Fraser Posted January 10, 2017 Administrators Posted January 10, 2017 Great, we'll try and get your issue resolved!
