TP Link C7 v2.0 problems with etherenet and wifi speed


im quite new with OpenWRT i installed to my TP Link C7 v2.0 router OpenWrt 23.05.0 and i have fiber internet,my ISP gives me 1Gbit speed,but max speed in my router is over wifi is just 150 mbit over ethernet cable only 100 mbit.Can someone tell me how should i configure this router?

Your router is almost a decade old by now, 150-200 MBit/s are the expected maximum for an ath79 device, you need (much) faster hardware for 1 GBit/s.
