Re: [Connectivity] Uploads only working on 1 laptop in the house
The behavior has not been consistent - the reasons for the modem switch was that after a week, my downloads wouldn't go higher than .5mb/s - uploads were non existent. Second modem (same model) they gave me was also bad. This set up works flawlessly with downloads, and uploads only really work on the laptop I used to set up and activate the network which is why I feel it's a DNS/IP address issue.
Modem: CM820 Router: Wireless N 100 WNR1000v2
I just hooked up one of the problem device to the router directly and the issue was resolved for that particular device which is interesting so I guess in this case plugging in directly once will fix the issue? Is this something common? I am a software engineer but I do not work with networking that much - I just moved out of my parents house for the first time where I've had internet set up for me my whole life haha.
The MTU (Maximum Transmission Unit) was set too high - It was 1500 which should be ok for comcast, but I guess it was sending packets that were too large which was crashing my network - Not sure why the difference, but setting it to 1470 did the trick!
