Been looking across the internet to try & find solutions to my speeds being slowed down to half or less from what I was getting before. I moved into this apartment where the equipment wasn’t mine & I was getting 130mbps down on my PS4 & skip ahead to now I’ve replaced the equipment with a CM1200 modem & XR300 router & at this moment I’m getting speeds around 70 on my iPad & around 40 (Wired) on my PS4Pro. I was messing with the settings the other day & it seems like a glitch happened where the R-Apps weren’t working but doing speed tests I was getting 130 on all my devices. One of my roommates restarted the router this morning not knowing there was an internet outage & now I’m back down to my speeds being cut. I’m pretty sure it’s something in the settings but I can’t figure out what exactly. Please help. I prioritize my PS4 over everything else.

If you connect a pc/laptop directly to the modem's port 1, what speeds do you get? (reboot the modem after disconnecting router, then hook up pc)What firmware is on the xr300? Optimal settings guide is found herehttp://support.netduma.com/support/solutions/folders/16000090646

Would suggest using the guide above. How exactly have you given priority to the PS4?

After doing speed tests on my PS4 via being connected to the modem I ran 5 tests and I got 119.7Mbps, 348.8Mbps, 353 Mbps, 151.4Mbps, and 357.5Mbps. I had my PS4 prioritized from the QoS giving my game consoles the most bandwidth usage. I haven't changed anything yet for the optimal settings yet to allow the speeds come through properly and the firmware is on whatever the newest firmware to date, I don't have a PC or laptop so I don't think I'd be able to install an older firmware if all else fails.

And what speeds do you pay for?

Honestly I'm not sure, my landlord pays for the internet but seeing as how I can get around 350 I'd like to aim for that but I'm generally happy if I can maintain speeds 100-150 im messing with the settings to get high speeds and I'm not seeing a "disable IPv6" option. I went to settings then advanced settings then IPv6 but I don't see any option to disable it. Also does the CM1200 have a bridge mode? I did a quick Google search & saw someone say that a modem that isn't a modem+router combo doesn't have that, it's always in modem mode, is that correct?
