When my Family asks Questions about there slow internet or signal drops ect, This is what I tell them.
Direct Connect Modem to a computer, do a speed test.
If the Results look decent, browse the web, listen to videos or music on youtube, play a game ect.
if results look good, and there is no issue, then your router is the problem.
Now if just the modem to computer results are poor or very bad.
Here is some things you can check, make sure the modem is not near a window of light, and not over-heating.
Check the Rubber pads under the modem to make sure there is at least 1/4th of an inch amount of space .
Unplug modem for 5 minutes to cool off, then plug the power back in.
Test the results again, if still poor, you can login to your account online or call your ISP, and have them ( Refresh the signal ) from there end, and they will basically Reboot the modem from there end.
This process will make sure the firmware/software of that modem is up to date as well.
If still low performance, then I would say let the ISP know, and have them send out a Tech to your home, They have devices that can test the strength of your signal.
Sometimes it can be something simple has an Old Coax Cable to the outside of your home to the pole, or Old Ethernet cable ( as they say, replace cables every 6-7 years ).
The Coax Cable if installed professionally, From Pole to House, will normally have a splitter 2 inputs, 3 outputs. There should be a ground wire that is attached to it, sometimes those get Rusty/corroded over time.
( Never do it yourself ) , always let a certified tech do it just to be safe. The Ground wire they would cut the end of the wire, and just peel back the rubber a little.
If all of that has been checked, and still bad signal, then your ISP truely is just bad.
Now::: If everything is good Modem to Computer ect, but
modem to router, seems to be the issue.
Same thing make sure the router is not over heating, Unplug it 5 minutes, plug it back in if everything is good but , bad after 10 minutes.
Thats an over heating issue, you can try putting extra rubber pads underneath. to give it some height.
Its possible the Ethernet cable is bad.
its also possible the Router is bad.
Good Decent Router : NetGear Nighthawk , and make sure to get one with like Wifi 7, then you know its up to date/new .
As always, test your internet with multiple devices, just to make sure your computer is not the problem ect.
hope this info helps.
It is always going to run better when it is plugged in because it's shielded by most interference and running full-duplex. iPhones have very good wireless cards and antennas. So do most Chromebooks.
If you want your wireless to work. Connect to your routers 5Ghz Band within 50 meters. (6Ghz if you're rich and have a quad band router) or 2.4Ghz Band between 60-100 meters. Crank the signal strength to 100%. Most importantly, remember that Wi-Fi runs at half-duplex. If you run 1gb internet and you want 1gb wireless speed. You need a router that has a 5Ghz band capable of running a minimum of 2ghz. Most Brands of AC1750 advertise 1750mbps. That is false. The AC1750 standard runs 2.4Ghz at 550mbps and 5Ghz at 1200mbps divided by 2. For wired, a simple Cat5e UTP cable is fine. Use STP if you are near an elevator, microwave, ect. Your wireless card also needs to support the same speeds and bands as your router in order for you to use them. Another thing that happens, especially with cable ISPs is cables get old or damaged. If you did everything I said and still get bad speeds. That could be why.
