Internet turned slow when summer started advice much appreciated

[GibbyG5o1]

Hello I currently have issues with my Internet and i,m hoping this is the right place to post about it(sorry if its too long of a read)

I got internet for my computer back in October of last year and it was pretty decent I could play videos games with little to no problems with a speed of 8Mbps the ISP is a local one that provides for 2 towns currently. the around late November and early December the internet was bad for some reason but the issue resolved itself and I paid no mind to that, but now ever since late May my internet has become bad very bad I only get good internet in the morning around 6:00 to 11:00 am but when it hits noon its just gets slow very slow and during late evening hours my games are at a constant 999 ping with 12% to 14% Packet Loss. I have run speed tests and I only seem to be getting around 0.98Mbps out of the 8.00Mbps I'm supposed to be getting I keep thinking when summer is over and fall comes around the issue will hopefully resolve itself. this is my first internet service I have ever gotten and i'm completely clueless about what to do

More Info:
- I use a linksys wireless G broadband router
-my isp has put an antenna so I can receive internet
-I have my modem connected to my PC via cable
-My PC takes up most of the internet around the house phones and other devices become slow
-My sister who lives literally 20 feet from my house got her own antenna and placed it right next to mine because again my PC took up all the internet
-I have called my Isp about the slow internet but that was last year during november and they just did a speed test and measured my speed from their office so I dont think they will be much help
- only like 2 other people in my street have their own antennas Idk if other neighbors have different internet
-I was wondering if upgrading to a 12Mbps plan will fix my problem but that sounds stupid when I really think about it
-idk if other isps cant run internet where I live because I live right outside the city limits
-If I change to a more "big" ISP willl I still have this problem?
-I have a satellite dish on the other side of my house facing the same way as my antenna towards a big tall Cell tower a mile away from where I live
-I have two old rusted antennas that were last used in 2008 can these interfere ?
-I'm really stupid and lack a lot of common sense but will this issue really resolve itself when fall comes around
-sorry for the long read

Could be heat related. Something is getting hot, expands and interferes with the overall connectivity.

Or could be some cumulative damage has just increased and performance may be degraded even when things cool down some.

That said, the following line in your post caught my attention:

"My PC takes up most of the internet around the house phones and other devices become slow".

If performance is good for the other devices without the presence of your PC then there also may be some configuration issue.

You mention having your PC connected to the modem via cable. Normally connectivity would be something like:

ISP antenna - --> coax cable --->cable modem -----ethernet cable ---->router ---ethernet cable----->PC(s) and/or wireless to wireless devices.

Take a look at the diagrams and setup instructions provided by your ISP to see if your network setup matches. What make and model is the cable modem?

Are you able to run and post the results of "ipconfig /all" (without quotes) from the command prompt?

The results may help identify a configuration issue.

I ran an Ip/config and this is what I got:

as for instructions on setup they have none on their website and never provided instructions or a manual,the ether cable It is "U/UTP CAT6 28AWG* 4P" (sorry if this is not the identity but its the only thing written on the cable) its a really long cable that runs from my room to the modem in the living room

The 192.168.1.1 IP address is most likely your Linksys router. The router should be configured to provide dynamic IP addresses to your network devices.

However, if both the router and modem are attempting to provide IP addresses (i.e., your computer is getting its IP from the modem instead of the router) then that all becomes problematic.

May not be heat related but not sure about the time frame (6:00 - 11:00 a.m.) aspect. Do more network devices come online at that time?

Go online and see if you can find the User Guides/Manuals for both your modem and router. Take a look at the physical connections (wires) and the configuration settings for both devices.

The modem should have DHCP turned off and the router should be the sole provider of DHCP IP addresses.

Take another look at it all and we can go from there. In the meantime someone else may post some additional thoughts and ideas. No problem with that.

The DNS server IP 192.168.100.1 may be amiss. What make and model is the modem?

Go into your network adapter settings and change the DNS Server to 8.8.8.8 or 8.8.4.4 (both Google).

Also if you do not have IPv6 then uncheck the option but only after trying the Google IP setting.
