Asterisk & suggested wireless router

Hi there,

We have just has asterisk installed by professionals and all is good.

Many of our calls are breaking up though, we have a wireless network and a pretty basic 11mbps 2.4ghz wireless router..I was wondering which router would give us faster & more reliable network speeds?

1.Gigabyte® 11Mbps 802.11b Wireless Router, 1 x WAN, 4 x LAN, 64/128 bit WEP Standard, Roaming and MAC filter

2.Gigabyte® 11/54Mbps 802.11b/g PCI Internal Wireless Router, 1 x WAN, 1 x LAN, 64/128 bit WEP Encryption, Smart Setup III, Firewall, VPN

3.Gigabyte® 11/54Mbps 802.11b/g Wireless Router, 1 x WAN, 4 x LAN, 64/128 bit WEP Encryption Standard, Smart Setup II, Firewall

4. Gigabyte® Turbo G 108Mbps 802.11g Wireless Router, 1 x WAN, 4 x LAN, 152 bit WEP Standard, WPA and WPA-PSK Authentication


Thanks in advance for your help :) :)

i've used some of the turbo G wireless routers before and they were pretty fast.

problem is that your network will slow down to the slowest device connected to the network, so if you have a 802.11b device connected, the entire network will only run at 11Mbps.

have you tried changing to a diffent channel?
 
nope, login to the control panel of the router and change the channel, that easy or not?
 
I'm not familiar with Asterisk so perhaps you should give us more info please. What are you using to connect to the router, ie: PCs with PCI Wi-fi 802.11b cards?
 
Why dont you guys PM each other your numbers, and then post here what the solution was? :)
 
Then there is no use in going to 802.11g. Either move closer to the router, consider Cat5 cabling or use repeaters to get better range.
 
thing is, the router cant handle when 2/3 people are talking through wireless network & asterisk box...it breaks up...we are in a open room, not big. get an excellent connection...
 
I agree, looks like bandwith is the problem. Switching to a 802.11g router will probably fix that, but then you will also need to swop out your .11b cards for .11g cards.

Since it's a big open room, just shout to each other, will be cheaper :)
 
its when we are all speaking to someone, via asterisk, over the network

I wish it was that easy. we have recently bougth the new .11b cards and so i dont think the new cards are an option. our installers have recommended an 11mbps sanau router for just over R1000.....not sure if this is an option
 
You problem is that wifi is half-duplex. (ie: send and recieve cant happen at the same time)
The least you can try is upgrade to 802.11g (54mbps)

I would still recommend that you go get yourself a roll of Cat5 and start running cable points to every phone.
 
VOIP over WiFi

Trouble is WiFi doesn't prioritize your VOIP packets. If someone is copying files over the network while you are talking you will experience problems. What voip softphones or hardphones are you using? Some suggestions:
1). Set your jitterbuffers on the phones to larger values. You will experience a little more lag, but less breakups.
2). Use a low bitrate codec like g729, g723 or gsm instead of g711. Asterisk can bridge g729 calls, but you need a license to do transcoding between codecs.
3). Just use cat5. An ethernet switch is full duplex, so someone copying files won't have such a big impact on your calls.

Just a question, why are you doing voip over wifi in a single cell? The cell radius is so limited, won't it be easier to just shout.......

I am connecting to a Asterisk Server on a SAIX Diginet via Wireless connection
and experience no call breakup
Xlite on Notebook <-> Senao 11Mb Bridge <---> AP (1 km away) <--> 256k SAIX <<---->> 128k SAIX <----> Asterisk Server >>> Telkom PSTN

Downloaded a 20 Mb file running the Asterisk Echotest effective d/l 3-4 Mb/s, and experienced no breakup, have not implemented QoS and used the iLBC codec (29kilobits/sec), GSM (35 kilobits/sec).
Then downloaded a 400 Mb and simultaneously uploaded a 70 Mb file and
their was no breakup just a delay on the speech being echo'ed
