Advice on install please

i have booted into recovery on my i5 1035G1 hp 15 dw2xxx laptop with iGPU (uhd graphics) with 8 gb ram and intel wifi (PCIe) i believe , now firstly before the recovery screen i get a scrambled screen and when i move the windows around it lags and the borders pixelate , is this a major problem ? or can i continue install , my trackpad doesnt work too , i know i have intel wifi....but is there a way to use wifi instead of ethernet ? sorry for the silly questions....
