Copyā¦Iād rather see a +6 Rx than an almost 53 Txā¦just for fun, do a speed test now & see whatchaā get.
293 Mbps
came up a bit about 30 Mbps
Should I try a 6db attenuator?
I wouldnātā¦Iād leave it aloneā¦6 db isnāt gonna hurt you at allā¦but 45 db on the upstream is way better than almost 53! Nopeā¦Iād let it beā¦itās just fine. Iām scratching my head on your speed coming downā¦not sure if itās on your end or the cable plantā¦maybe something at the tapā¦hopefully, your tech takes the time to figure it out & not worry about getting to their next job.
thanks for the help
10:15 pm here
have to get some sleep, work tomorrow
will log on again Tuesday night

By removing the 10 DB Attenuator and restarting modem the upstream amber led is now off.
Hopefully the tech can address my low speeds Saturday.
Will post results Saturday evening.

Roger that MCatā¦kindaā impressed that your gateway has warning lights for signal parametersā¦pretty cool feature. If I had one Iād be fiddling around with my signal to see exactly where they were setā¦altho, itās probably right there in the manualā¦ha ha.

Ok here is my up date.
The original tech replaced all the connections on my coax.
Claims I was getting 1300 Mbps on his test equipment.
Iām paying for 600 Mbps and getting 300 Mbps on a network connected laptop speed test on a good day.
Tech said he is putting in a work order to replace the coax from the pole to my house because it is old.
Nobody came.
I scheduled an appointment for yesterday, no show again.
Was on the phone with Xfinity for over an hour tonight.
After all their testing they said to contact my modem/router manufacture Netgear.
Ask to have my modem/router configuration checked.
Netgear basically said to pay $138 for the one year service package because Iām past the 90 free coverage.
Unbelievable
I was paying for 300 Mbps and getting 300 Mbps. Got a free upgrade to 500 Mbps and was getting 400 Mbps. Got another free upgrade to 600 Mbps and now getting 300 Mbps.
Sounds like your tech was an hourly in-house Comcast guy & didnāt want to run a new house drop for youā¦let the contractors hang itā¦ha ha. Thatās okā¦now, if heās getting 1.3gigs coming into your house (over an old house drop) & youāre only getting 300megs out of your gatewayā¦then, assuming he & his meter are correctā¦itās sounding like your gateway is maybe the problemā¦or possibly a setting of some kind in your gatewayā¦? I assume you checked hardwired speeds thru all 4 ethernet ports & they all only max out @ 300Mbpsā¦& wifi also same. I would like to have seen your tech hook up one of their gateways & checked your speeds thru itā¦as that wouldāve definitely shown your gateway as the culpritā¦or not. You can always go to the local Comcast shop/office or have one sent to you to see if your equipment is the problem. I donāt know MCatā¦Iād rather see you figure out for sure what the snafu is before you go spending big $$$ on another gateway.

Good point, ether its the isp modem or gateway, or the old lines. If he tested the incoming connection and everything was in the right order, line noise flaps and what not then it would have to be the modemā¦ the tech should have tested the isp maintained equipmentā¦
Id fight this. Aslong as you removed all your own routers and stuff and did a hard check on a wired connection on a 10/1000 connection.

Iām not buying anything theyāre telling you. If they claim to be getting 1300mbps at the house on their equipment, have them substitute yours to confirm. Then you can trace where (if anywhere) the problem is. Iām still convinced its their setup and nothing to do with the line or your equipment. Unfortunately, these ātechsā usually arenāt the sharpest tools in the box!

MCatā¦a couple of more thingsā¦I wouldnāt be overly concerned about the replacement of your house drop cable at the momentā¦yes, itās probably old & needs replacement (generally 7 yr life span for aerial drops) but if the tech got anywhere near the speed he told you, & didnāt mention any other signal related problemsā¦I would say your house drop cable is definitely not a concern for now. To give you & everyone some contextā¦the ISP (Comcast) is responsible for everything (the quality signal & connection you contracted for) from their service tap at the utility pole to the house box where the drop cable comes in & connects to a āproperly groundedā ground block. All internal wiring is your responsibility (unless they installed it) as is any equipment that is not owned by Comcast. If they have to repair anything inside the home thatās not theirs, then itās considered a service call & will cost you their going rates. Now, with that being saidā¦could/should your tech have disconnected your gateway & hooked up one of theirsā¦then taken a signal test AFTER it to show the signal strength you contracted for (I wouldāve) but each technician is different. Thatās why (before you buy new equipment) I would suggest you rent a Comcast gateway for a monthā¦or just get one & try it out for a day to confirm the problem is your personal equipmentā¦you can always take it back the next day & say nevermind, Iāve decided to use my own equipmentā¦they may prorate your rental to just a day or two. Hope all this makes sense

He did do some checks just before my owned modem/router.
I checked all four ethernet ports on my modem / router to a windows 7 lap top,
299, 320 293 344 Mbps
wifi 43 Mbps
IPhone 12 pro Max
wifi 178 Mbps

is this a comcast router? Is it possible this is a 300mb capped router. Its what it sounds like.
Netgear C7000v2 good to 600 Mbps
Modem / Router
I own it.
Out off 90 day warranty.
Thatās why No one wants to touch it.
Xfinity says it not out modem
Netgear wants you to get $139 service plan.
Going to try and get Xfinity box to test with somehow.
Pick one up at local Comcast store or they will mail one to youā¦not sure if they charge to ship their equipment these daysā¦but always askā¦they are sneaky with hidden costs. Monthly rentals are probably around $14/moā¦hopefully, not higher but depends on region. If gateway works & you get your 600Mbps youāll have your answer & can go on from thereā¦I know going thru this is a pain in the buttocksā¦so good luck

xfinity in my area has their new super-duper gig router free with 1 year contract and unlimited data. Not a bad deal but I have all my own equipment and the trick here is that you forget after a year and the charges kick in
