I've had the same issues...barely touching 300 Mbps down on Gigablast after two tech visits and I have brand new NETGEAR modem/router, new coax cables, and new CAT7/8 ethernet cables. Did a speedtest right in front of a tech with a plug from his meter to my laptop and back again and both showed dramatically different speeds (their meters aren't like normal "customer" devices). We also did a Panoamic COX modem swap and the speeds on there were poor. I think the NODEs/Cox infrastructure is overwhelmed...they just don't want to tell you that. Re: Download Speed ????? If your neighbor has a faster speed package, he will get slightly higher speeds. If you're doing a test there...the best test is to take your own modem and actual coax cables and ethernet cables to test it there...however, that's annoying cause you may have to call Cox and provision a new MAC and serial number for your modem on your neighbor's account. I have Gigablast and have been barely getting a third of the speeds. I've had the same issues at the Cox box (demarcation point) where my speeds are bad...even after a Cox tech re-wired some stuff. I hooked up my own new coax to the Cox box and got the same bad speeds. Cox's tech meters don't seem to go through the same "traffic pattern" as customers do. It's similar to speedtests on NETGEARs Apps which will almost always show faster speeds than you're getting. Their meters also seem to have a dedicated "server" to them back at a Cox main office in the area. Additionally- I've learned that the Speedtests appear to be measuring how "fast" you can touch the internet, but not the responsiveness of actually accessing and using the internet. Re: Gigablast Speed way below Expected in Northern Virginia Yup. I've tried various servers (besides Cox)..I've tried ones in DC, ones in areas within a 10-20 mile radius, I know which ones are "faster". I signed up for DSLReports, used the tests there and posted there. I've done various speedtests on various sites and its all the same. The Cox meters are "powered by Ookla Speedtest". So it's Speedtest.net technology, which they've farmed out to companies like Netgear (and they use it on their routers/modems and their Netgear App). But as mentioned above, it's not a true throughput test as it's measuring connectivity to a point..such as "the internet" or that your devices speeds should be 1 Gbps but you're not getting that. For example, your car can drive over 150 MPH to get to the grocery store, but realistically you're only going to max out at maybe 55 mph on the high-way because of traffic. From my understanding, this is why the meter tests are always bias..they say you CAN and SHOULD get that speed...but are never actually factoring the traffic, etc. unless you're on an actual computer (car) going through the "normal" route. My Netgear app (with the Ookla Speedtest) for my RAX45 router SAYS its connectivity to the internet is 500+ Mbps Down. But it's touching an "entrance point"...not the way a computer or any interactivity device would. I've taken a break on the internet stuff. Been dealing with it for two weeks since I moved in. But yeah, something is definitely off. Re: Gigablast Speed way below Expected in Northern Virginia It's a good point. It's not a normal speed test. When my second tech was here...he was waiting on some test results and was on the phone with another tech and an engineer at their Fairfax office. Turns out their "server" was down...as the other tech he had on the phone had the same issue. They swapped servers and were able to get their meter'ed tests back up. That's why I think their meter Speedtest is similar to the Netgear Nighthawk app (both are actually powered by Ookla Speedtest.net). Which only measures the router speeds to the internet (actual modem)...which are usually clocking 500 Mbps+. It's testing that connectivity to their server but not going through the normal "customer" route. Re: Gigablast Speed way below Expected in Northern Virginia The tech was only able to observe these wired speeds on his measuring meter device. I confirm that I saw them too as I watched it. He also saw speeds drop when we switched over to the Macbook wired-to-modem tests. I have done the directly into the modem tests with two different devices (a relatively unused Macbook Pro and my late-2000's iMac) with brand new Cat7 and Cat8 cables. I confirmed a link speed transmission of 1 Gbps on each device. My iMac desktop was also formerly hooked up at my old residence with Xfinity and was wired to a router. I was reaching 500-900 Mbps speeds there. I don't have any bloatware/malware/firewalls/etc. that should hinder speed. The iMac/Xfinity hook-up was a little over a week ago and my speeds were fine there. Its only when I moved to my new house (3 miles away and a different county) and had to switch to Cox is when I started encountering these speed issues. My laptop is unused and is "clean" since it's a former work laptop and doesn't have any games, apps, etc. But I did update it to the latest OS (Catalina) before we did all the testing. The second tech confirmed I had no splitters hooked-up (we removed those after the first tech visit). He was on a call with a colleague and even commented that my laptop is fine and should be seeing high speeds (He could see the laptop tests through my open door to the outside where he was standing). Re: Gigablast Speed way below Expected in Northern Virginia Thanks! But I have Macs. KNow anything similar for them? Re: Gigablast Speed way below Expected in Northern Virginia Yes, and I was using a Cat8 and Cat7 cables to test Re: Gigablast Speed way below Expected in Northern Virginia So I had a tech come out, he was awesome. Very detailed and helped troubleshoot more than the last one. He fixed some of the wire crimping that the previous one did and we tried everything again. Previous crimping and connections wasn't so good and he showed me why. This is VERY strange - He was getting over 900 Mbps down when we tested the connections and my modem on his device. We were able to hook it directly because my connection box internally and modem is close to the outside back door so we were able to use my extended cables so he didn't step inside. We speculated that maybe the inside crimps jobs might be causing issues...but we barely pushed ~250-280 down on my laptop wired to the modem. Why is his device showing over 900 on the modem and my wired laptop was MUCH less? After he left, I tried another test...I avoided the coax that comes into my house and wired one outside in the COX box to their orange wire. This should've been getting 900 Mbps down...BUT NO, ~250 Mbps again. Is it possible that the COX set-up in the demarcation point (there's a metal connection between the COX orange cable and the cable that comes into my house) needs to be replaced? I really liked the tech, he was detail-oriented and even showed me what he was seeing so I was able to validate his findings. This is a real head-scratcher. Anyone with similar experiences?

So I plugged it straight into the coax that runs to the small COX box at the back of my house. Uncorrectables are gone....0. However, speeds still seem to be at the same... I also stopped by my old house (that had Xfinity/Comcast at 1 gig down/30 up and did a random wifi speedtest and got 562 down/30 up) standing next to the router. Back at my new house...standing next to mine with Cox, I get about 100 down/35 up. There's a 3 mile difference between my places but it's different counties. ~~~~~
