I have a problem which i would like to share with you. I have a dell laptop and a HP system. I regularly use both of them. I use a wifi connection on both of them and as i have to use internet alot so i have an internet plan which give me upto 50mbps speed. A week ago everything was going fine, but don't know suddenly my internet speed got decreased to almost 0 to 1 mbps. I contacted my internet service provider, they changed the modem after trying with all troubleshoots. Now the thing is that my laptop is running like always (speed is near about 40 mbps) but my hp system still have the same problem. the speed is hardly reaching 1 mbps. I connected my phone with wifi and speed is 40+ in that too. So now every device is running on full speed except my HP system. Please let me know what troubleshoot i can do to resolve this as i am already very frustrated.
Important to mention that my laptop and system are both placed on same place and in same room. I use wireless LAN card on my HP system to get wifi connections. I thought maybe that card is not working properly but when i connected same HP system with my phone's hotspot then speed was coming very good. I have tried various things :-
1. I removed that wifi network, restarted the system and added network again
2. I unistalled Antivirus also to check if that was causing issue
3. Changed the place of modem and cpu as well
4. Deleted browsing history/cache/cookies
5. Changed the port of Wireless LAN card
I am using windows 7 on both machines and please don't ask me to try using lan cable because that will not be possible due to modem wire setting. Please Please help me in this. I am eagerly waiting for your answers. Thanks
