Mixed G/N?

I found the same issue (if this is an issue).
I'd love to be able to use N for my work laptop will my old media center runs on G...
Any ideas why it's not present?

DD-WRT supports NG-mixed mode.

Great, thanks. I found this link that makes me re-consider it, though: Don't Mix Wireless B/G with N Wireless N is supposed to be interoperable with Wireless A, B, and G, but it doesn't always work that way. Some older clients might not be able to connect at all, even when the wireless router or APs are in mixed wireless mode. Then when the older clients can connect, they'll slow down the network. Some clients may take a heavy 80 percent cut in their throughput. To prevent this problem, consider forcing the new APs to use only Wireless N, and keep the old router or APs around to support the old clients. Although connections among users on the Wireless N router or APs with Wireless G users will still be bottlenecked by the old clients, the throughput cuts on a mixed mode Wireless N router or AP can be much worse. From: http://www.informit.com/articles/article.aspx?p=1349392&seqNum=3 I knew that using mixed mode drops the speed of N to 144mbps, but I didn't think it affected the B/G speeds too.

The above link does not even give an explanation why that rates would drop in case you mix G and N:-) So the above info is probably based on some test he did with some hardware without knowing hardware and implementation details. In addition to that he says use the same manufacturer, this is also half way true. He talks about problems with the standards, but if you use for example the WNR3500L, Asus RT-N16, Linksys WRT610v2 you have the same radio unit with the same driver provided by broadcom, therefore you can exchange these and have the same shit. On the other side, you can get netgear routers and cards that have radio untis from different oem, like ralink, broadcom etc. then you may run into problems because your radio units are from different hardware manufacturers.

Honestly, although this guy claims to be an network expert, he knows little but nothing.

It is not neccessarily true, that speeds drop if you mix G/N. If you have a dual radio unit, then you pretty much have 2 radios at the same time. In this case you don't have this problem.

Next thing is, once you mix G/N you probably have 2 Clients that transfer data, if they transfer at the same time, then due to the protocol speeds are cut in half. Just image you have two people in a room. If both talk it's not working so one has to listen the other can talk. So one always has to wait and therefore he cannot talk as much as if he would talk alone.

it works with N/G clients.
