To the uninformed:
700 ms ping
IS the "lag" (aka: latency)
By signs of "lag" I'm sure you mean
packet-loss which means your gaming experiences is jittery to the point where it's unplayable and you die alot.
So what you have is a high latency with no packet-loss making WoW playable over Neotel.
However, as with any wireless provider. The more congested it gets the more packet-loss you will get.
Sentech started out GREAT.... got congested
iBurst started out GREAT.... got congested
3G started out GREAT.... got congested
WiMax started out GREAT.... got congested
The limitation to wireless is the radio tower. It doesn't always have the necessary ability to expand in terms of bandwidth required to sustain many users. thats why you'll have many towers covering 1 area (as with a cellphone). If a tower is congested and gives you the best signal, you will be bumped to one with less signal that's not as congested. Even though this sounds like a good idea, once the tower closest to you isn't congested anymore you get bumped back to the strongest one and guess what.... it causes packet-loss.
I
loathe wireless with all my being. It has always let me down and will always let me down.
That being said... I'm trying Telkom Wimax as a last mile solution...
