Sounds like levels must be off they will try to correct it, if all else fails make them run a new line from the drop outside your house

TestMy.net's servers are on a network that has direct peering with some of the biggest names in the Internet backbone. With multi-homed connectivity and bandwidth from over 25 independent Tier 1 carriers including Comcast, Cox, Time Warner, Charter, Qwest, Google, Level 3, Internap, NTT America, Equinix & Telefónica to name a few. The network has a total capacity of over 2000 Gbps and our servers have multiple gigabit uplinks into that network. TestMy is always overstocked with bandwidth and can meet the needs of even the most demanding connections. Our servers are also configured and tested to maintain full quality of service for thousands of miles.

Most modems I've ever had run hot signal level won't affect it

Honestly I would setup a small pc on the network with VNC or remote desktop enabled and just log in and run tests when you receive complaints

Tbh the problem is most likely out of your control the only things you could check would be make sure the modem and router aren't having any issues check your modem logs see if there are many errors swap out the ethernet cable between modem and router and if you have a spare router try it out see if you still have the issue. It sounds like an outside issue though something probably along the connection route that is timing out

Awesome!

I would check your adapter settings make sure it's set to full duplex not half duplex also check your ethernet cable by swapping out for a spare if you have one

unfortunately the geolocation isn't perfect, i'm sure CA3LE will be along with a much more detailed response soon

I would honestly try them all out no one can tell you what will be best because WiFi can be tricky. Placement of the devices can also have an effect on which frequencies are best for your house

If you close the tab or browser window the test should stop our test can't run in the background without the Web page being loaded

Honestly it sounds like a bad modem or phone line or even a bad filter I would first swap out the modem since that should be done at no cost then if that doesn't work try replacing the phone line and or any filters your using also make sure your plugged in to the modem/router via Ethernet when testing to help eliminate any other possibilities make sure you do one thing at a time when trouble shooting to help diagnose the problem

Also 5Ghz band will have a harder time with walls etc than 2.4Ghz keep that in mind I would play with your wireless settings and bands till you start getting a more consistent string of tests that is of course after you get your network running the way you want it

Depending on the wireless capabilities of that router it could be the limiting factor usually when a WiFi router is connected to devices the link speed for all devices will operate at the slowest device speed so say you have a device connected on wireless G and one on wireless N they are all going to operate at the slowest negotiated speed which would be wireless G. wireless G is max theoretical speed is 54Mbps even if your connected at 54Mbps you won't get that due to packet loss and interference you'll probably only achieve about 80% 43.2Mbps in addition the test here will also be stress testing your HDD if you have a slower HDD such as a laptop HDD you may have issues getting a higher speed as well try using the multi threaded tests and make sure no other devices are connected to the WiFi when testing such as cell phones etc they have a really hard time maintaining high link speeds which will affect the link speed for your laptop especially if they are connected on wireless G

There are ways to test and see if your lan or computer are causing the problems but you will need two computers to test it basically you could setup a local file transfer using lighttpd or something along those lines or use a ftp server on one machine and transfer a file to another tests like that may rule out your lan if your lan is not causing the issue then it's out of your control aside from calling and complaining... Quite a while back I was having issues with Cox it took me 3 months of calling multiple times a week to finally have them send out a maintenance tech who swapped out a local amplifier that appeared to be working right was showing no issues once he swapped it my problems disappeared make as much noise as you can is my only advice just try to be polite to the technicians they are just doing their job

That's very odd usually they provide higher level of service to businesses in terms of speed and reliability I'm assuming you've tried the common things such as a new modem, no router, changing your cat5 cables out? Have you had the techs install new fittings try adding an attenuator?
