While the slow client is transmitting data, due to CSMA-CA, no other client can transmit. A slow client will take significantly longer to transmit its packet of data than a fast client. Similarly while the AP is talking to a slow client all other wireless devices on that channel will have to wait for their turn. The slower the device the longer that the ...

You'll want to upload and install tcpdump for tomato. You'll need to wget the file and host it somehow and then wget it onto your device. Put in /usr/local/bin or some /bin in your $PATH for easy keeping. See link for file: link Once you get it installed run something like this (modify for proper interface) tcpdump -i eth0 -n port 80 See tcpdump cheat ...

Yes. Generally speaking, a G-only network is about three times faster than a mixed B/G network. Please see the following: What do I need to transform my network from Ethernet to WiFi? From the Cisco White Paper Capacity Coverage & Deployment Considerations for IEEE 802.11g "When 802.11b clients are associated to an 802.11g access point, the ...

I'd recommend dumping the Linksys firmware and load up DD-WRT. It's a far superior firmware for the WRT54GL with enterprise-like features. Turns that $60 router into a $600 one (software-wise). If it's still having issues, it may be the hardware.

Acquire a wireless card that supports "Monitoring" or "rfmon" mode and use it in conjunction with Wireshark to view the 802.11 headers in your network traffic. This is wildly chipset, operating system and driver dependent but Wireshark has some nice documentation to point you in the right direction. What you are after is the actual 802.11 management headers ...

Based purely on observation I refute that theory. I frequently have machines connecting to the same point at different speeds and none are affected when another connects at a slower speed (other than by virtue of them all sharing the same feed bandwidth.

You didn't mention which authentication protocol you are using. "WPA2 Enterprise" is an umbrella term. Are you using EAP-TLS? Or PEAP-MSCHAPv2? Do you have client certificates in place or just the CA certificate + username/password? Depending on the actual protocol, the authentication error happens at a different protocol stack level. If you are using ...

You would need to re-flash the firmware with something like DD-WRT which can get you full access to the underlying Linux OS. From there you can configure the iptables, etc. to do whatever you wish on the different interfaces. You will need a firm understanding of Linux routing, this is not for the casual end-user. The main page for the DD-WRT project is ...

Designating one of your "Lan" ports to be connected to the neighborhood wifi network shouldn't be too difficult if you use a firmware that gives you access to the underlying IP stack, such as DD-WRT. However... I'd then like to set up routing so than some traffic is routed to ADSL, and the rest to the Mikrotik. This is the tricky part—What you want to ...

Instructions for setting up load balancing under dd-wrt are at: http://www.dd-wrt.com/wiki/index.php/Dual-WAN_for_simple_round-robin_load_equalization However load balancing is usually profoundly dissapointing.

If you don't need to apply any firewall rules for the second network, then you don't even need iptables, just a static route like.. ip route add 172.16.0.0/24 via 192.168.0.3 where 192.168.0.3 is the address assigned to the lan interface on the Mikrotik device. according to http://en.wikibooks.org/wiki/Tomato_(firmware)/Menu_Reference#Advanced there is ...

We have many WRT54GLs running and we have had our share of lemons; sometimes occurring right out of the box and sometimes after a period of use. The problems seem to be consistent though: no internet access for wired clients and no DHCP for wireless. Also, no remote access. Usually the power LED on front of the router is rapidly flashing. Sometimes a ...

Thanks for your reply. Finally figured out that this behavior is as spec'd by the firmware. As part of a boot-up failsafe mode, the firmware always assumes 192.168.1.1 for about 5 seconds before assuming the programmed IP address. During this brief window, you can tftp a new firmware in case you accidentally bricked the router. It would take a very low ...

You can't do #2 because the wrt54gl doesn't have a DSL modem built in. You can't plug a phone line into an Ethernet jack and have it work. However, you might be able to put the beetel DSL modem into bridge mode, letting the wrt54gl handle PPPoE, NAT, and DHCP service. That's probably the way I'd go. Do you have the ability to reconfigure the beetel modem?

If you're talking about 4MBytes/s, i'd say that this is near the max that a wrt54gl can handle. Here is the result of a IxChariot test, with streams in both direction. Note the avg speed of 36Mbps, which 4.5MB/s.

If you are sure about that cost is not an issue then get a real Cisco access point (like cisco aironet) avoid linksys if you can. http://www.cisco.com/en/US/products/hw/wireless/index.html Linksys is ok for home and small offices. It is not recommended for anything bigger however. You can even get a WLC (wireless lan controller). It's a bigger investment, ...

Not sure about Raspberry but I know I run DD-WRT on my WRT54Gs at home at it works like a champ. I've got OpenVPN running on it and the performance is damn good considering my crappy Time Warner line at home it connects over. Either way they have done a good job at keeping the footprint down in size and still providing a nice experience. It is also fairly ...

It sounds like you want the WRTs to act as AP/bridges not routers, and that you already have DHCP running on the 192.168.0 network. If you want your wireless clients on the same network as the wired connections you need to setup the DD-WRT as an AP not a DHCP enabled router. Basically just disable DHCP on the WRTs and connect them via LAN ports instead of ...
