UPDATE, LESS THAN 50 MINUTES AFTER POSTING THIS. We got a call from our internet provider, they got the FCC complaint and will be here in 10 minutes. (long story short, this is after been blown off by a lower level employee and refused my request to have someone come and check it out.I have never thought about anyone complaining to the FCC about an issue with the internet company. Thats interesting... Did you threaten to cancel your service and ask for the retention depart?
I was surprised my ISP offered me $10 off per month to keep me just last week when I told them to pull the plug! I always found the secret is not asking for a discount but telling them I'm leaving as I have decided to go with a less expensive ISP... I can get T-Mobil Home Internet added to my cell service for $35 a month so as long as you got a cell tower around you got options as far as less money and a way to cut the cord... But, that 500/500 you now have sure would be missed going with Cell Home Internet... Sometime you just gotta "Pay The Man"...
I have no idea of your exact wifi setup or router location and home layout but based on my experience your provider may not be far off suggesting you need to be connected directly to the router via a Cat-6 cable as so many things WILL slow the wifi signal down.
The age of your WIFI unit or even the age of the phone, PC card can cut the speed in half vs wired.
I had very bad WIFI using my ISP rented $5 a month WIFI so I purchased a multi node Mesh wifi system and now I have great wifi... I now even have a Mesh wifi node in my detached garage so I now get reliable wifi at all locations inside or outside my property.
However, my mesh WIFI is now getting old so if I want to keep up with GIG or GIG+ speed its time to upgrade but for me and my wireless WIFI needs as long as I have a rock solid wifi connection ( I do ) I'm okay not getting the 1G wired speed as my now aging mesh wifi caps out at around 500 Mbps so I get about half what my wired devices get but again, its a ROCK SOLD 500 Mbps via my Wifi and ALL my computers I have hard wired and get my 1 Gbps download speed.

Ok, with the above said, tech spent well over an hour here. He was able to get us up to 500 down but the upload was all over the place, peaks and valleys and could not get us over 350 at any point, most times lower. Using of course a direct connection with his iPad AND a laptop.
Had multiple calls with his office too.
He cleaned the optical sensor outside the house (or something like that) he said it was dirty (?) dust but not enough, went to the distribution box a few houses down and all other kinds of stuff. But no good. Got over 500 down consistently but could not get over 350 (on a good run) Bottom line is he replaced the modem with the same one. now will get up to 525 down and 475 up on a good run. up is a little weak but add the two numbers together and its close to 500/500 = 1 gb
Some history of myself. Im well versed in all things WiFi, though now retired. I have worked in both commercial and residential with security systems, cameras, locks, thermostats etc. Actually I am the one they sent to business and customers to trouble shoot if another tech screwed things up. (most times it was the customers crappy equipment.
I knew something was wrong and glad they found something. Tech was great, I always treat the workers with respect, it's not their company. He is going to follow up even everyday if I wanted, I told him Thursday would be fine, told me to continue doing my tests.
There is another solution if any other more problems he mentioned another modem but it is a large modem he mentioned but prefers not to install it if he doesnt have too, as it will take up all the room in my Legrand type box.
