you could get a replacement Wi-Fi card for that device, either internal or external via USB, though it is sort of a questionable investment for that unit given the fact that they're not worth very much these days, they can't run any currently supported version of macOS without relying on something like opencore Legacy patcher (which you should be on anyways on that unit now)
Quick and dirty test is also to try it out with multiple completely completely unrelated networks like a café or friends house or school or anything like that. If it persists across all of them then it's a device issue, if it works fine on all of them then your home network shit
