Here's an example...
If a neighbour is using 6 and another using 11.
If you then use channel 8, this is wose than you using 6 or 11.
Why? Because you are bang in the middle of interference from BOTH 6 and 11.
If you use 6 or 11 your router will be on the same channel as a neighbours yes.
BUT it will try not to transmit data at the same time as the neighbours, so you avoid wireless collisions and data needing to be sent over and over...
On channel 8 you are invisible to 6 and 11's routers. You get interference from both and your data collides with theirs mid-air. It's overall going to degrade their network performance AND yours.
Using channel 13. You get interference from 11. You get collisions mid air. It's worse than actually sharing the same channel...
Hence why we don't see channel 1,2,3,4,5,6,7 etc all being used.
It's done methodically to avoid interference.
1 6 or 11 will work for you.
If 1 is dropping out use 6 or 11 etc.
Channel 1 doesn't overlap with 6. So if the issues are on channel 6 they wont be on channel 1.
The admin may have used say channel 3 or 8 like in the example above. This would cause more issues and possibly drop outs. Afterall they're using 13 which is bad practice.
