I tried channels 1, 9 & 11 and it would either get very slow or drop out the wireless completely. Thank goodness for 5 Ghz. Yes the range is not as good but at least it does not keep dropping out. Most of the time I am in the same room as my router only about 2 meters away.
If your client is 2 meters from the router and you are getting signal drop outs or significant slow downs then it may not be due to neighbors' 2.4 Ghz transmissions.
The problem may reside on your end:
1) Your router
2) Your client's NIC card and/or antenna(e)
3) Electrical interference in your home or possibly a neighbor's. This can be from anything that uses electricity (or batteries or wireless signal such as computer mouse, radio-controlled toy, baby monitor). For example, an electric knife cut my signal in half while being used 3 rooms away.
4) Physical barriers to signal between your router and client. This can be any object(s) such as walls, furniture, glass, plumbing, etc.
5) Some other issue with your computer or software not directly related to WiFi signal.
Specifics on your router model and client NIC as well as you doing some testing of signal would be helpful. If you have a WiFi-enabled notebook computer then use iperf/jperf or LAN Speed Test to test multiple locations for throughput. Do not rely on internet based speed tests as there are confounding variables that can confuse the accuracy.
