Router swtiching

*arris surfboard N300 | 300 SBG6580

@Laflame2737, no.  A Surfboard would be a DOCSIS "modem," not a DSL modem.   Your speed issue is most likely your distance from the Central Office.  If you need higher speed, you'll need to see if AT&T can upgrade you to VDSL2 or fiber service; see if they have some wireless option that will suit, or go somewhere else.

I have uverse fiber optic but it’s only running at 16 down 0.94 down. The modem is a arris nvg510 it’s a couple years old could it be the modem or the service plan I have?

As my thoughts stated, the NVG 510 is an ADSL2+ router, not a VDSL2 router.  I didn't notice on my first read that it was an upload speed of ~ 1 Mbps you were having issues with.  That's the best AT&T will do on ADSL2+.  Your download speed is pretty good for the 18/1 ADSL2+ service as well.

How do how do I find out if my service is IP - RT
