By default, our Linksys router's MTU size is set to auto at 1500 even if you choose different types of ICT. Our Linksys router's WAN interface is set to auto MTU so that our router will be the one to adjust accordingly to whatever type of medium is your Internet Service Provider using.

Important Note: MTU must be 1492 (or lower) when using PPPoE connectivity. More detailed information about the effects of MTU can be found here. Important Notes: •Due to additional complications, VPNs require a different type of MTU test. Please refer to the end of this article. Linksys MR8300 _____ 35 Environmental _____ 35 to clone MAC addresses and set MTU (maximum transmission unit). 27. Port Settings Port forwarding—for a single port, multiple ports or a range of ports—sends traffic inbound on a MTU, or maximum transmission unit, is the size of the largest packet that the network can transmit. Anything larger than the set MTU is broken up into smaller fragments, which essentially slows down the transmission. Most home networks are set to its router's default MTU settings. There are 2 partitions and Linksys firmware is copied to both partitions at the factory. When you install/update the Linksys firmware, or install/update OpenWrt, the new firmware is always written to the other partition. wifi_virtual_start(ath0) [utopia] Not setting ppp_clamp_mtu wifi, wifi_user_start(ath0) wifi_user, ath0 TxBF enabled wifi Ideally the MTU should match between your PC, router and ISP. See the Linksys Blue-Box Router HOWTO here for tips on how to use, administer and troubleshoot Linksys boxes from a Linux system. Some Linksys models have an "Auto" MTU capability that does not function correctly and you must enable the "Manual MTU" function and manually enter 1492 (or less). To isolate whether the Linksys

Setting the correct MTU size can make a difference in optimizing your network speeds. The MTU size, or Maximum Transmission Unit Size, is the largest physical packet size, measured in bytes, that a network can transmit. Any messages larger than the MTU are divided into smaller packets before being sent. The default setting of the MTU size on Peplink routers is 1440 to accommodate for the Typically on a PC, you can set the MTU of the NIC to match the established L2 network MTU. An L3 device can then correct MTU mismatch by IP Fragmentation. Since my switches are in L3 mode, it seems like I should be able to set the MTU for a particular L2 VLAN. Thanks The ip mtu command is used to provide room for the GRE and IPv4sec overhead relative to the local physical outgoing interface IPv4 MTU. The tunnel path-mtu-discovery command allows the GRE tunnel IPv4 MTU to be further reduced if there is a lower IPv4 MTU link in the path between the IPv4sec peers.
