Hi Everyone,
I have been playing around with wireless bridging and have an issue that you might be able to help with. I have a wireless bridge and when I hard wire into the bridge I get my full 10Mbps download speed. When I hook my dir-655 into the bridge and make connect to the wifi of the dir-655 my downloads go down to 3Mbps. Does anyone have any ideas? When the dir-655 tries to determine wan speed during a reboot it takes a lot longer than usually. Below is a rough diagram of the connection. Any help would be great!

why not do this
Modem-----Dir 655<----->wireless bridge<------>wireless laptop
you have a 2nd router connected to the modem in front of the wireless bridge and the dir 655?

Long story really, but basically in the end trying to create a seperate private wireless network thats different from the main wifi router. The house had an odd layout where the modem is currently sitting.
But in theory should be there be any reason why I would see such a drop due to the dir-655 or why it has trouble establishing the correct wan speed? Any settings I can look at? I am running 1.20. I was going to force it to 100Mbps instead of auto for the wan link, but not sure what else to check. I though for a minute it might be the dir-655 and the bridge having wifi issues being so close to each other but they have different ssid's and different channels and hard wire into the bridge I get full speed so the wifi doesn't seem to be an issue.
Thanks for any more insight!

Do you have DhCP disabled on the Dir 655 and have the connection type set to static ip?
-
Tell me the type of modem and connection, 1st router name and model,wireless bridge name.

The dir-655 is setup to act like a wireless router. I will expand my diagram below. Basically I am making the dir-655 it's own private network off from the main network in the house. Basically the main network in the house uses 192.168.1.1 and from the bridge I connect into the WAN port of the dir-655 and assign it anything on the 192.168.1.x subnet for it's WAN ip. The internal lan/wireless of the dir-655 is using 192.168.2.x subnet. This basically segregates it into two networks.
Modem ---- Main Router <----> Wireless Bridge ------- Dir-655 <----> Laptop
192.168.1.x Wan 192.168.1.2 / Internal 192.168.2.x

Modem is your basic comcast modem. The main router is a netgear wgr614 and the bridge is a linksys WAP54G running dd-wrt
-
I just checked one more thing, I forgot. I hard wired into the dir-655 and I got full speed. So the only issue is not getting full speed when connected via wireless. I guess any thoughts on what I can check there? If the two routers have different ssid's and channels then they shouldn't interfere with each other right? THe main router is uing channel 11 and the dir-655 has auto scan on and it using channel 2.
-
try inssider, you can find what channels are being used and assign channels less used to the routers. I would disable auto scan and pick a channel.

Just curious as to why 2 networks, 2 routers, seems to make config more complex then has to be from the info you gave me.
-
I am trying to test out some stuff for work and this network would mimic that environment
so besides the channels, any other reason the wifi connection would be slow? They are already different channels. They are using 2 and 11
thanks

Disable auto scan for wireless channels. Set "G or N only" in wireless connection.
Your comcast modem running DHCP, NEtgear and Dlink DHCP should be disabled.
Interference from other devices, keep the Dir 655 from other devices as much as possible, also you could try moving the antenna. The idea setting is \ | / but you could try moving them.
-
Your comcast modem running DHCP, NEtgear and Dlink DHCP should be disabled.
You can not enable or disable DHCP on a cable modem and Comcast does not let you have a static IP.

DO have a surfboard modem? I saying the cable modem should be running DHCP and manage devices connected to WLAN. Your netgear has a static ip as you should also within the netgear config assign a static ip for the Bridge and within the Bridge config assign a static ip for the Dir 655. The only device running DHCP shold be the modem or 1st router, any others running DHCP will cause double nat and connection problems.

Internet Connection Type
There are several connection types to choose from: Static IP, DHCP, PPPoE, PPTP and L2TP. If you are unsure of your connection method, please contact your Internet Service Provider. Note: If using the PPPoE option, you will need to ensure that any PPPoE client software on your computers is removed or disabled.
Static WAN Mode
Used when your ISP provides you a set IP address that does not change. The IP information is manually entered in your IP configuration settings. You must enter the IP address, Subnet Mask, Gateway, Primary DNS Server, and Secondary DNS Server. Your ISP provides you with all of this information.
DHCP WAN Mode
A method of connection where the ISP assigns your IP address when your router requests one from the ISP's server. Some ISP's require you to make some settings on your side before your router can connect to the Internet.
Note: If you are connecting the router to a DSL modem or cable modem, and the modem uses DHCP to assign IP addresses in one of the private subnet ranges (for example, 192.168.0.0 – 192.168.255.255), it is likely that the modem is performing NAT and that connecting the router in DHCP WAN Mode will cause double NAT. Double NAT -- having two NAT devices in tandem -- can cause problems with some networking functions, such as DMZ, port forwarding, and VPN. In this case, it is preferable to use the modem's user interface to disable NAT on the modem, then connect the router using the WAN mode appropriate to the no-NAT state of the modem. For example, some DSL modems allow you to specify that PPPoE is implemented on the router. If you select that option on the modem, you would then select and configure the PPPoE WAN mode of the router.
Host Name: Some ISP's may check your computer's Host Name. The Host Name identifies your system to the ISP's server. This way they know your computer is eligible to receive an IP address. In other words, they know that you are paying for their service.
Use Unicasting: This option is normally turned off, and should remain off as long as the WAN-side DHCP server correctly provides an IP address to the router. However, if the router cannot obtain an IP address from the DHCP server, the DHCP server may be one that works better with unicast responses. In this case, turn the unicasting option on, and observe whether the router can obtain an IP address. In this mode, the router accepts unicast responses from the DHCP server instead of broadcast responses.
PPPoE
Select this option if your ISP requires you to use a PPPoE (Point to Point Protocol over Ethernet) connection. DSL providers typically use this option. This method of connection requires you to enter a Username and Password (provided by your Internet Service Provider) to gain access to the Internet. The supported authentication protocols are PAP and CHAP.
Dynamic IP: If the ISP's servers assign the router's IP addressing upon establishing a connection, select this option.
Static IP: If your ISP has assigned a fixed IP address, select this option. The ISP provides the value for the IP Address.
Service Name: Some ISP's may require that you enter a Service Name. Only enter a Service Name if your ISP requires one.
DHCP Server Settings
DHCP stands for Dynamic Host Configuration Protocol. The DHCP section is where you configure the built-in DHCP Server to assign IP addresses to the computers and other devices on your local area network (LAN).
Enable DHCP Server
Once your D-Link router is properly configured and this option is enabled, the DHCP Server will manage the IP addresses and other network configuration information for computers and other devices connected to your Local Area Network. There is no need for you to do this yourself.
The computers (and other devices) connected to your LAN also need to have their TCP/IP configuration set to "DHCP" or "Obtain an IP address automatically".
When you set Enable DHCP Server, the following options are displayed.
DHCP IP Address Range
These two IP values (from and to) define a range of IP addresses that the DHCP Server uses when assigning addresses to computers and devices on your Local Area Network. Any addresses that are outside of this range are not managed by the DHCP Server; these could, therefore, be used for manually configured devices or devices that cannot use DHCP to obtain network address details automatically.
It is possible for a computer or device that is manually configured to have an address that does reside within this range. In this case the address should be reserved (see DHCP Reservation below), so that the DHCP Server knows that this specific address can only be used by a specific computer or device.
Your D-Link router, by default, has a static IP address of 192.168.0.1. This means that addresses 192.168.0.2 to 192.168.0.254 can be made available for allocation by the DHCP Server.
Example:
Your D-Link router uses 192.168.0.1 for the IP address. You've assigned a computer that you want to designate as a Web server with a static IP address of 192.168.0.3. You've assigned another computer that you want to designate as an FTP server with a static IP address of 192.168.0.4. Therefore the starting IP address for your DHCP IP address range needs to be 192.168.0.5 or greater.
Example:
Suppose you configure the DHCP Server to manage addresses From 192.168.0.100 To 192.168.0.199. This means that 192.168.0.3 to 192.168.0.99 and 192.168.0.200 to 192.168.0.254 are NOT managed by the DHCP Server. Computers or devices that use addresses from these ranges are to be manually configured. Suppose you have a web server computer that has a manually configured address of 192.168.0.100. Because this falls within the "managed range" be sure to create a reservation for this address and match it to the relevant computer (see Static DHCP Client below).

I am pretty sure nothing is wrong with my dhcp and ip scheme or I wouldn't get the full download speed via the hard wire into the dir655. It's something with the wireless so I will play with those settings. Might replace the dir655 with another spare wireless router I have and see if it makes a difference as well.
Thanks

Best of luck.
