Basically I have wifi in a suburban area, unfortunately I used to get speeds of 45mps on wifi but now due to my neighbours all using wifi daily to download and probably stream netflix my speeds are around 19 mbps and can drop randomly to like 1mbps for a few secounds. Not ideal for online gaming. Sometimes my connection will drop long enough to kick me out of a game losing all my progress. I put my network on channel 13 (least congested, wifi app rated every other channel 1 star 13 was 4 star out of 10) and my pc was back up to 45 mbps speeds. The only problem is my old laptop i need to use occasionally from 2005 does not connect/find our router. Is there away to make old devices connect to channel 13 manually. Can I do this and why is it not connecting. I got a warning whdn I changed it saying some devices might not connect.
