Update = After verifying ownership and completing troubleshooting, a DELL agent setup service to replace the WiFi antenna.
I experienced that my Wifi Connectivity is very poor and unacceptable. Wifi indicator shows very low signal strength and  internet speed is very low. I informed this to Sri Lanka's Dell agent (Singer Sri Lanka PLC) and they told me that they changed the motherboard as well as wifi adapter, but experience results were same as earlier. Then again i handed over my laptop to agent on 31/12/2021 and up to now they didn't give any response to me. All my work held up and now am really disappointing due to bad performance of the laptop and behavior of the agent. (I test the speed of the internet with another laptop (My Office laptop but other brand) and it was awesome. However my Dell laptop gave me unacceptable results and online meetings were dropped but same was not experience with my office laptop at the same location with same router. can anybody from Dell or in the community support me to get rid of this issue? Thanks Gune
