Hi list,
I have a wireless router with 2 wireless cards: 2.4Ghz and 5.0Ghz frequency.
The performance for 2.4Ghz is much worse than 5.0Ghz.
Does the frequency affect performance so much?
Thanks,
Lin Ming

There are a lot of factors:
- Amounts of other networks on the same channel
- Noise
- Signal strength
etc.
It's quite possible that there are less networks on 5GHz channels
where you are so there's less noise, stronger signal, and therefore
better performance. Most routers are still only 2.4GHz.
Thanks,

In addition to this you may wish to check your channel width. You may
be using 40MHz channels on 5GHz and 20MHz channels on 2.4GHz.
