2.4ghz network issue

[stook1]

Very interesting. I really appreciate your coming back on this! I will have to verify just to be certain, but I am fairly certain I am running 40mhz mode on both 2.4ghz and 5ghz. In the case of 2.4ghz, I am running channel 1 / upper. For the 5ghz, I just left the channel on Auto since I can't see any other 5ghz networks. I can see some other 2.4ghz networks but I don't have many neighbors and nobody seems to be really using the lower channels (other than me).

My worst performing transfers were from a location separated by a half floor, a few walls, and around 60 feet. So based upon that I guess my performance is pretty decent. I'll test again with 20mhz.

Anyway, this is on the new router. The old one seems to be shot, after all. I can't even get 1 MB/s on the 2.4ghz band doing the same tests from the further away locations, although when next to the router I get very good performance. The connection also doesn't seem to be stable, I seem to get variations in transfer rates from moment to moment.

A lot depends on that interference factor and also how exactly it is running.

Is it set in 40MHz mode for 2.4GHz? It looks like maybe not, as those are the kind of number running my router in 20MHz mode. I get around 14.5MB/sec absolute max near my router with my laptop, when the router is in 2.4GHz 20MHz mode.

The 5GHz numbers are very similar to what I get on my AP when it is set in 5GHz 40MHz mode.

That would certainly explain the speed discrepancy. If the only option is "auto", then odds are good it is selecting 20MHz mode for 2.4GHz.

At 7ft from my AP, I get ~23.5MB/sec on 2.4GHz 40MHz and 25.5MB/sec on 5GHz 40MHz. With my router I get ~28MB/sec 2.4GHz 40MHz and I can't equivocate with 5GHz, as I don't have the option of setting the 5GHz band to N only on my router (its an AC1750 router), but when I do set it to 40MHz channel width, I get about 30MB/sec absolute max on 5GHz (but that is still 11ac, which is going to be nominally faster than 11n for the same channel widths close to the router).

Setting my router to 20MHz channel widths I max at about 14.2-14.5MB/sec on 2.4GHz. With a wall and 30ft in the way I get around 13.5MB/sec. Move a floor up, at about the same distance, but with the floor and a couple of walls in the way and I get around 11MB/sec on 2.4GHz (with 20MHz channel widths).

If I move REALLY far away, with 50-60ft, 3 walls, floor and the dinning room table in the way I get around 4MB/sec on 2.4GHz 20MHz and around 8-9MB/sec set to 40MHz mode.
