New WRT150N intermittently slows network access

    I just replaced my old, reliable WRT54GS with a WRT150N (newest firmware). I mostly use a MacBook Pro. While the new router technically works, my network speed slows down considerably several times a day. Specifically, internet access speed sometimes halves (or worse). It also slows down network access, so that if I copy a large file from my server, it just hangs there for minutes. Interestingly, if I turn my MacBook's Airport off then on, it seemingly fixes the problem until the next time it happens. Any suggestions? Thanks...

    P.S. naturally it happened just as I was submitting this post -- just hung it for more than a minute...

    I just installed a WRT-150N and have four different machines using it. Two PCs with G wireless cards, a PowerMac with an Airport Extreme card and a MacBook Pro with the N-enabler extension installed to active the draft-N wireless support. So far I haven't seen any slow down issues. Is your router set up in auto mode or have you selected a specific channel? I know I saw some oddities when I initially set up the router that disappeared when I picked a specific channel. For example, both my old WRT-54G and the new router seem to have trouble with channel 1 so I use either 6 or 11. I am currently using 20 MHz narrow channels for N wireless but am about to start experimenting with enabling the wide channels and leaving the G wireless traffic on channel 11.

    Thanks! I switched to narrow and to channel 6 and that seems to have solved my problems.

    I would also note that Linksys released a firmware update (1.01.9) the other day. Also, I have run into issues with Mac OS X clients being unable to connect with wireless G when wide channels are in use. Linksys sent me some beta firmware (1.02.0) which resolves that issue. They also told me that the default configuration of Radio Band, Wide Channel and Standard Channel being all set to Auto can be problematic in RF noisy environments.
