Have just installed 2710VN as my ADSL Router, network switch and Wireless AP. I have a iMac and PC on Wireless connections and a PC, Netgera ReayNAS, PS3 and Wii connected via the switch. Running itunes across the wireless causes stutters and pauses with the music files located on either PC or NAS box. Tried with older Buffalo ADSL Wireless G Router and all is fine.
Tested copy speeds and got rought 3MB/s copying files from the wireless machines to the wired interface (either PC or NAS) but when I try copying same files back from PC or NAS to wireless PC or MAC I get dire results (15MB file takes on average 100+ sec so <150KB's)
Anyone got any ideas as it is definate only an issue transferring one way!! i.e. going from the draytek 2710Vn ethernet interface and out through it's wireless

Have run out of ideas. maybe a faulty box?

Found the answer, WEP key encryption does NOT play well with draft-N WiFi. I disabled the WEP security and now the same 15MB file copies in 2 sec rather than over 100 - One happy man
Itunes streams now great and iphone syncs fast.
Hope this helps others
